Striking while the iron’s hot: Arkansas 4-H club teaches blacksmithing skills to new generation

By Rebekah Hall
U of A System Division of Agriculture

RISON, Ark. — The metallic clang of hammers rang out at the Pioneer Village in Rison, where members of the Cleveland County 4-H Blacksmithing Club forged their own tent stakes from low-carbon steel.

The club’s monthly meeting took place April 19 during the Pioneer Craft Festival. The Pioneer Village, a collection of historical homes and structures dating back to the 1800s, includes a blacksmith’s shop built by local volunteers. Ed Montgomery, leader of the Cleveland County 4-H Blacksmithing Club, said the location has been perfect for their group.

LESSONS IN FORGING — At a meeting of the Cleveland County 4-H Blacksmithing Club, held at the Pioneer Village in Rison, club member Millie Montgomery explains how club volunteer Jeff Frey and his son Brayden Frey are heating a piece of low-carbon steel to be hammered into a tent stake.

“This was specifically built to be a blacksmith’s shop,” Montgomery said. “Two retirees named Bill Gray and Luther Drye built this from used sheet metal and lumber from Luther’s sawmill. They donated their time in addition to the building materials. It’s been a great thing for the kids and the Pioneer Village.”

Montgomery said his passion for blacksmithing first began as a kid, when he was a member of the Scott County 4-H Buckskinners.

“Our club wasn’t all about blacksmithing, but as part of it, we had a forge,” Montgomery said. “None of us knew what we were doing with it, but we just got out there and learned what we could. It really took for me. I don’t do it for a living, but I just love to do it. Since then, I’ve collected as many tools as I can and just continually learned about it.”

The Cleveland County Blacksmithing Club began meeting in the fall of 2023, and its members include Montgomery’s three children.

“I enjoy showing this to them,” Montgomery said. “It’s passing on something that I feel is an important skill.”

At their April meeting, 4-H members shaped small pieces of low-carbon steel into tent stakes by tapering and sharpening one end to be hammered into the ground, then using the tip of an anvil to curl and press the top of the stake into a tight hook.

Members also operated hand-cranked blowers to keep a stream of oxygen flowing into three separate forges, which were heated using blacksmithing coke. Blacksmithing coke is coal that has been heated to burn off moisture and other substances, resulting in a fuel that burns hotter and produces less smoke. To get the coke burning, members first kindled a small wood and coal fire.

Montgomery said club members have made hand-forged nails, wall hooks and dinner bells.

As part of their blacksmith training, club members have also been taught hammer signals, which are helpful for team striking, when two people take turns hitting the same piece of metal.

“That’s a traditional way of communicating in a blacksmith’s shop,” Montgomery said. “At times, it can be too loud in a blacksmith’s shop to hear verbal instructions clearly. Taps on the anvil with a hammer can tell the ‘striker’ when to start and stop.

“And they’re learning teamwork – there’s no time for a kid to argue in this,” he said. “Participants learn that when the metal comes out of the fire, work must start on it immediately.”

David West, Cleveland County extension agriculture agent for the University of Arkansas System Division of Agriculture, said the 4-H Blacksmithing Club is “helping get kids active, build self-confidence, teach them a useful and practical skill and help them build relationships.

“It has so many positive layers to it,” West said. “Learning safety with tools and how to follow instructions, and expressing your artistic ability and imagination through heating, hammering and forging. I heard one student say it can even be therapeutic to hit some steel with a hammer.”

The club was recently awarded an Innovative Grant from the Arkansas 4-H Alumni Association and Arkansas 4-H Foundation. The grant recognizes 4-H programs that benefit more than just one club.

“Through Ed’s leadership and direction, along with many volunteers who have stepped up, this club is showcasing 4-H and 4-H’ers to their entire community,” West said.

Hands-on learning

Montgomery’s daughter Millie, 15, has participated in the club since it started.

“It’s a dying art, blacksmithing is,” Millie said. “Nobody really knows how to do it. I really enjoy it, and I like to help other people do it because it’s fun.”

Montgomery’s son John, 16, said he enjoys blacksmithing as a creative outlet.

“I was inspired, like many others, by a show called ‘Forged in Fire’,” John said. “I would say that blacksmithing is a good way to get some experience working with your hands. You have fun, you can work, and you can make money.”  

Desiree Frey, whose son Brayden, 13, is a club member, said the experience has helped her son practice his creativity and improve his social skills.

“I never knew anything about blacksmithing until we got into 4-H, then when they started this, I thought, ‘Oh Brayden, that would be really cool to get into,’” Frey said. “He’s made a lot of things. He’s made a couple of dinner bells, plant holder hooks, a spoon and nails.”

Jeff Frey, Brayden’s father, is a club volunteer. He said it’s important for young people to learn about hands-on trades and explore different career paths.

“College is great, but it’s not for everybody,” Frey said. “Blacksmithing might not be something you do day in and day out, but to be able to see you can do something like this, it’s good. I work in a paint and auto body shop, and you do all that work by hand. There’s a pride in that work, and that’s what I see in a lot of the kids here. Whenever they see the final product, they look at it, and they’re like, ‘I made that.’”

Katie Jo Strother, 14, who recently joined the club, said she enjoys coming to meetings to see her friends and take advantage of the unique opportunity to learn.

“You don’t see this kind of stuff anywhere around,” Strother said. “To be in my hometown and doing something that we all love, it’s just fun.”

Montgomery said his goal for the club is for members to continue growing in their confidence and abilities.

“We’ve really seen their skills increase, from barely being able to hit the metal to really hitting accurately,” he said. “I want to see them progress in their skills and make more and more complex things. My goal is for them to be able to work with their hands and work with their intellect, that way they diversify their abilities as they enter adulthood.”

Extension to host free FAMACHA certification for goat, sheep producers in western Arkansas

By Tracy Courage
U of A System Division of Agriculture

LITTLE ROCK — Producers of small ruminants can get certified in using the FAMACHA system — a tool for managing parasite control in goats and sheep — at a free training offered May 2 by the Cooperative Extension Service.

FAMACHA — Joan Burke, an animal scientist with the U.S. Department of Agriculture’s Agricultural Research Service Dale Bumpers Small Farms Research Center, will be the guest speaker at a FAMACHA certification training on May 2.

Attendees will learn about the biology of the main parasites that affect goats, sheep and other animals and learn about integrated parasite management. They’ll become certified in using FAMACHA — short for Faffa Malan Chart, a diagnostic method for identifying the presence of Barber’s pole worm — Haemonchus contortus.

“As barber pole worm is a bloodsucker parasite, a high parasite load can decrease appetite, affect digestion and cause anemia,” said Dan Quadros, extension small ruminant specialist for the University of Arkansas System Division of Agriculture. “In severe cases, parasite infections can kill sheep and goats. FAMACHA is an easy, accessible method to check the animals and determine if they need treatment.”

The training will be held 8:30 a.m.-noon at the Sebastian County Fairgrounds, 530 E. Knoxville St., Greenwood. The training is free, but online registration is required and available at https://www.uaex.uada.edu/famacha25.

Joan Burke, a research animal scientist with the U.S. Department of Agriculture’s Agricultural Research Service Dale Bumpers Small Farms Research Center, will lead the training.

Burke has researched the control of gastrointestinal nematodes in sheep and goats. Her program addresses issues that producers may encounter with their livestock, such as organic and grass-fed production systems for ruminant livestock and alternatives to synthetic dewormers, such as specialty forages, genetic and genomic selection for parasite resistance, nutrition, and products such as copper oxide wire particles.

Burke is also one of the founding members of the American Consortium for Small Ruminant Parasite Control.

Solar leasing on agenda for NALC, NASDA Foundation’s Mid-South conference

FAYETTEVILLE, Ark. — To install, or not to install, that is the question — and attendees of the 12th Annual Mid-South Agricultural and Environmental Law Conference will have the chance to hear perspectives on solar lease agreements and solar development from two experts in their respective fields.

While renewable energy efforts such as solar panel installations have increased in recent years, there are many factors for farmers, landowners, and developers to consider before making the decision to work together on a long-term project.

At the Mid-South, Seth Hampton, member at Rose Law Firm, and Will Veve, land acquisition and development at DESRI, will discuss both sides of the transaction in the session, “Solar Leases and Development in the Mid-South: Pointers and Pitfalls.”

The conference will be held June 5-6 in Memphis, Tennessee, and is co-hosted by the National Agricultural Law Center, or NALC, and the National Association of State Departments of Agriculture Foundation, or NASDA Foundation. It also features a livestream option. Registration, agenda and more is available at https://nationalaglawcenter.org/legaleducation/mid-south-2025.

Hampton has years of experience representing farmers, landowners and their lenders in negotiating solar lease and purchase options involving developments throughout the United States.

“Rental rates certainly make solar leases attractive, but there is much for landowners to consider when approached by developers about installing panels and related facilities on their land,” Hampton said. “Provisions concerning rental rates, land included within the leased premises, minimum rental/acreage requirements, crop damages, rights of third parties (such as easement and mineral interest owners, farm tenants and lenders), property tax increases, insurance obligations, early termination rights, decommissioning/restoration obligations and security, and more should all be considered before making a decision.”

Veve will bring insight regarding the developer’s perspective to the presentation, as DESRI develops, owns and operates U.S. renewable energy projects.

“Both developers and landowners have much to consider regarding coming to an agreement for the development of a project,” Veve said. “There is tremendous shared opportunity for both the landowner and developer. Having an open, collaborative process from the beginning is the most important aspect of this relationship to ensure both sides are successful.”

NALC Senior Staff Attorney Rusty Rumley says that NALC attorneys have heard an increased amount of inquiries regarding solar leasing in recent years.

“Solar leasing has been around for quite a while, but it garnered more attention in recent years due to the Inflation Reduction Act of 2022, which incentivized the adoption of solar through various mechanisms, like tax credits,” Rumley said. “It’s a topic that landowners and developers should investigate carefully before coming to an agreement. This session at the Mid-South provides an opportunity to learn about what to consider from both the landowner and developer sides.”

Continuing legal education available

The Mid-South will be submitted for CLE accreditation in Arkansas, Kansas, Mississippi, Missouri, and Tennessee. Approval for CE will also be sought from the American Society of Farm Managers and Rural Appraisers. Those who register by May 13 are eligible for bonus CLE/CE during the online “Early Bird” on May 14.

UADA tallies crop-related flood damage at ‘conservative’ $78.9 million

By Mary Hightower
U of Arkansas System Division of Agriculture

LITTLE ROCK — The University of Arkansas System Division of Agriculture on Tuesday estimated crop-related flood damage in Arkansas to be a “conservative” $78.9 million; and agronomists and economists warn additional acres may be flooded as water moves downstream.  

The estimate said that of the 839,798 acres reported planted as of April 7, 31 percent was reported as flooded.

Rice accounted for most of the flooded acreage at 46 percent; soybeans were next at 30 percent, followed closely by corn at 23 percent and winter wheat at 1 percent of the crop.

The assessment did not include peanuts and cotton, since those crops have later planting dates.

The analysis estimated the total replanting expenses from flooded acres for corn, rice and soybeans to be $42.04 million. The estimated replanting cost per commodity is:

  • Corn — $11.44 million

  • Rice — $20.91 million

  • Soybeans — $9.68 million.

Winter wheat damaged by flooding won’t be replanted, and with fertilizer and other inputs already invested in the crop, wheat growers will still face production losses and sunk cost of production. This places the loss for wheat at around $18 million, the analysis said.

The value of federal crop insurance indemnities — the amount insurance would pay back to farmers — is estimated at $18.69 million.

The Division of Agriculture released a fact sheet on Tuesday outlining these preliminary damage calculations. Agricultural economists and agronomists from the Division of Agriculture made their calculations based on observations from county Cooperative Extension Service agents.

“We recognize that this is likely a conservative estimate as we have not accounted for yield loss resulting from late planting, damage to farm structures such as grain bins, and unreported acreage that is flooded,” said Hunter Biram, extension economist for the University of Arkansas System Division of Agriculture. “We note that these losses are one-third of the projected economic assistance to be received by Arkansas crop producers highlighting the significance of this flood event in the face of multi-year declines in net farm income and heightened market volatility.”

When calculating the total damage costs, planting expenses are estimated using operating costs from the 2025 University of Arkansas System Division of Agriculture crop enterprise budgets, said Ryan Loy, extension economist for the Division of Agriculture. “Only cost items such as seed, fertilizer, herbicides, labor and diesel are incurred when replanting a crop, while the remaining operating expenses — including crop insurance, interest and cash rent — are only incurred in the initial planting.”

Deacue Fields, head of the Division of Agriculture who is also an agricultural economist, said the damage assessment is critical to help obtain aid for affected farmers.

“We created this assessment to help our farmers and are sharing our findings with Gov. Sanders and the U.S. Department of Agriculture,” he said, “Both are in a position to help the people of Arkansas agriculture through this very difficult time.

“We truly appreciate the speed at which our agents and faculty collected and processed this information under very difficult conditions,” Fields said.

The Division of Agriculture will conduct additional surveys to further refine the damage estimate.

Agriculture is the state’s largest industry, valued at more than $24 billion.

From April 2-6, Arkansas and parts of the Mid-South endured a series of storms culminating in what the National Weather Service labeled “generational” flooding. With more than a foot of rain falling in some locations, moderate and major flooding occurred along the Cache, Black, White and Ouachita Rivers. Water levels along those rivers were not expected to decline significantly through April 18.

Along the lower White River, the National Weather Service posted flood warnings until further notice.

Last week, Craighead County rice farmer Joe Christian posted an aerial photo of his farm on X, which showed the vast scale of the flooding. In it, the white roof of a storage shed surrounded by acres of brown water, with a few trees and outlines of fields visible.  

Satellite analysis

Jason Davis, assistant professor remote sensing and pesticides application and extension specialist, was analyzing satellite imagery of the flooding to be paired and validated against ground observations made by extension agents.

“We’re one of the very few organizations that can do this,” Davis said. “With our direct connection to producers through both specialists and the county extension agents we are one of the very few organizations in the state that have the network to do this kind of validation with such a quick turnaround.”

For his analysis, Davis has downloaded imagery of 11 million acres in Arkansas’ Delta. The images are multispectral, so in addition to visible light, he has near-infrared images which can be used to “show very clearly where the water is.”

Using the visible and near-infrared images to create false color imagery, all water — “even the really turbid water that may look similar to soil in visible spectrum imagery, pops as fluorescent blue so it can be differentiated as flooded.”

Davis said he will also produce a “quantified map of where the water is pixel by pixel, so we can calculate the number of flooded acres by that. I use those two methods to calculate and validate where the water is.”

Davis said he overlays the satellite imagery with maps from the National Agricultural Statistics Service showing “where crop fields are and what commodity that field was planted in each year.”  While the NASS data is from 2024, agronomists and economists can use these numbers as a baseline to adjust estimates based on what was planted and crop rotations.

Rice

The problem plaguing all farmers right now is uncertainty as water drains southward.

“We are still so much in the middle of this insanity,” said Jarrod Hardke, extension rice agronomist for the University of Arkansas System Division of Agriculture. In the next few days,  “there is ground where the water is coming off and ground that is just now going under.”

The rising water won’t be dramatic like the original flood event, but farmers “will just start to see water getting deeper every day,” he said.

In the Payneway community, “they started sandbagging it last Wednesday, expecting it to flood this coming Wednesday,” Hardke said Monday. “They’re having to read the tea leaves about when and how this is all going to play out.”

Complicating the predictions are the different rates at which the rivers — all tributaries of the Mississippi River — drain.

“There’s the expectation that when the Mississippi River crest gets to Helena, that they’re going to need to protect the Mississippi River levees. They’ll be turning off their pumps and that means a lot of the water we’re draining out of the St. Francis and other rivers is going to start to back up.”

As for a rice redo, “we know we have a ton of levy damage and impacts. Tearing down and rebuilding damaged levees — that’s a substantial investment of time and money,” Hardke said.

“There is actually a little bit of replant seed available — seed that was deliberately held back for that purpose,” Hardke said. “But it’s going to be hit or miss depending on the type of rice they need.”

Soybeans

Jeremy Ross, extension soybean agronomist for the Division of Agriculture, said the high moisture levels left by the flooding are causing seedling diseases in stands that have emerged.

However, “we are still in the heart of the optimum planting window,” he said. “With less than 15 percent of the crop planted, there’s still time to maximize yield.”

Growers looking for seed to replant their soybeans may “not get the same variety you had, but you can still get the herbicide technology you’re looking for.

“The way I look at it is the best scenario is cotton and peanuts because nothing has been planted,” Ross said. “Second best is going to be soybeans, just because seed supply is really good.”

Ross cited the case of a grower in east central Arkansas who planted 2,700 acres of soybeans and 300 acres of corn.

“They’re going to have to replant the whole farm because of drowned soybeans and being hit pretty hard with seedling diseases,” Ross said. “But while it’s a bad situation, it could be worse. It’ll be a little more cost to recondition the beds, run the planter and then make an additional herbicide application, but they still have an opportunity to maximize their soybean yield.”

Corn

When it comes to corn, growers are also still within a good planting window, said Jason Kelley, extension wheat and feed grains agronomist for the Division of Agriculture. He said there should be seed available for replanting, but “it’s probably not going to be the grower’s first choice. They might get their second, third or fourth choices.”

Kelley said the late planting date for full crop insurance is April 25 in southern Arkansas and May 1 for northeast Arkansas, so most people are going to be able to get back in the field and replant corn before yields start dropping from late planting.”

Some growers that had corn emerging and plan to replant will have an unusual task: killing the rain-damaged first stand before planting again, since the partial initial stand will act like a weed for the replanted corn.

“A lot of people are probably just going to use tillage to get rid of the first stand as many of the raised beds are eroded down that irrigation later in the season may not be as effective,” Kelley said.

Raised bed erosion is a real issue “Producers may have planted the seed 2 inches deep,” he said. However, when the heavy rains came, “those beds ‘melted down,’ so now that seed isn’t 2 inches deep and it’s not nearly deep enough for proper root development, which can lead to plants falling over and plant loss.

"The silver lining is that if this rain happened a month from now, it would have been even more devasting since now, at least, we have an opportunity to replant corn,” he said. 

Wheat

Kelley said, “Unfortunately for the wheat crop, we’ve got almost all the expenses in it already —seed, fertilizer, herbicides — so we’re basically waiting on harvest,” he said. 

“Wheat can handle some water for a couple days like other crops, but the quicker the water recedes, the better,” Kelley said. “If the wheat is heading or in the flowering stage and the flood water is deep enough to go over the heads that would most likely result in blank heads with no grain.”

CBD Oils: Do you know what's inside?

By Maddie Johnson
University of Arkansas System Division of Agriculture
Arkansas Agricultural Experiment Station

FAYETTEVILLE, Ark. — Since the 2018 Farm Bill effectively legalized hemp-derived cannabidiol — better known as CBD — there’s been an exponential growth in products hitting the market, but a newly published study suggests consumer understanding of the products has not kept pace.

“You’ve now got new products on the market that have never been there before, and so there's a pretty long learning curve for the average consumer,” said Brandon McFadden, professor and researcher of agricultural economics and agribusiness in the Dale Bumpers College of Agricultural, Food and Life Sciences and for the Arkansas Agricultural Experiment Station, the research arm of the University of Arkansas System Division of Agriculture.

CBD oils go by many names and contain a variety of ingredients. For example, “CBD isolate” only contains CBD, but “full-spectrum CBD” contains other compounds such as terpenes and flavonoids, which can contribute to aroma, flavor and overall therapeutic effects.

Full-spectrum CBD also can contain up to up to 0.3 percent delta-9 tetrahydrocannabinol, or THC, by weight — the legal threshold set by the federal government for hemp-derived CBD products.

Products with THC levels above this threshold would be classified as marijuana and considered illegal under federal law. THC is known for its psychoactive properties, but there is debate on whether any psychotropic or intoxicating effects are felt for THC levels below 1 percent, McFadden noted.

Considering the many types of CBD products and their distinctions, McFadden led a study surveying consumers to gauge their confusion when it came to product names. Those surveyed completed two product selection tasks. In both selection tasks, consumers chose between CBD isolate, hemp oil, full-spectrum CBD and broad-spectrum CBD, which is a middle ground between the isolate and full-spectrum choices and contains no THC.

In one task, respondents were provided the common name of three CBD oil products, as well as hemp oil, and were asked to imagine they were purchasing 1000-mg CBD oil for themselves or a loved one. In the other task, they were faced with the same choice but were given more information about the products’ contents. The content information included concentration levels of CBD and THC, as well as the presence of additional compounds.

MAKING YOUR CHOICE — The figure accompanied the study "Consumer Confusion About Product Names Commonly Used to Describe Hemp-Based Oils" and shows examples of the selection tasks survey respondents faced as part of the study. Mention or depiction of product names does not imply endorsement by the University of Arkansas System Division of Agriculture. (Figure originally appeared in study)

The consumers surveyed included those who had reported previous CBD purchases and those who had not. 

The study, “Consumer Confusion About Product Names Commonly Used to Describe Hemp-Based Oils,” was published in the Journal of Consumer Affairs in February.

McFadden said he was surprised by the study’s finding that there was significant interest in CBD isolate among those surveyed who had not previously used CBD products.

“It did seem like there were consumers who were potentially interested in purchasing CBD, but because there was such a learning curve and a lack of knowledge, they wouldn’t participate in the market,” McFadden said.

The findings also showed that for consumers with a strong preference, it was not easy to identify their preferred product based on product name alone. In fact, some consumers who reported previously purchasing CBD products had difficulty distinguishing between CBD oil types.

Co-authors of the study included Kawsheha Muraleetharan, University of Arkansas graduate research assistant studying food science and technology; Benjamin Campbell, University of Georgia professor of agricultural and applied economics; Adam Rabinowitz, Auburn University professor of agricultural economics and rural sociology; Tyler Mark, University of Kentucky associate professor of production economics; and Michael Popp, Harold F. Ohlendorf Professor of agricultural economics and agribusiness with the Division of Agriculture. Popp is also a Bumpers College faculty member.

The work was supported in part by a grant from the Federal-State Marketing Improvement Program from the U.S. Department of Agriculture’s Agricultural Marketing Service, project USDA-AMS-TM-FSMIP-G-20-0004.

Labeling made modern

To combat consumer misconceptions, McFadden pointed to the use of “smart labeling,” which uses technologies such as QR codes on product labels to allow consumers to gain more information than would fit on a printed label, especially the small bottles and containers in which CBD products are often packaged.

“It’s a very powerful tool across all products to provide more consumers with more information, fostering consumer education, which is particularly important for things like new products like CBD,” McFadden said.

McFadden added that these QR codes can take consumers not just to text on product information but to other media, such as videos, to aid in educating those who may not have done prior research.

“So that’s why providing them information at the point of purchase can be very important because they’re unlikely to spend much time before going to a store selling it,” he said.

Wholesale egg prices are decreasing, but expect delay in lower prices at grocery stores

By Rebekah Hall
U of A System Division of Agriculture

LITTLE ROCK — The national average wholesale price of eggs has declined, but consumers may have a wait before seeing lower prices at the grocery store, said Jada Thompson, associate professor and poultry economist for the University of Arkansas System Division of Agriculture.

EGG PRICES —  Though wholesale egg prices have declined, consumers may experience a delay in seeing that decline reflected in grocery store prices, which averaged $5.90 per dozen eggs in February. (Division of Agriculture photo.) 

Wholesale price changes can take up to three weeks to be reflected in retail stores, so consumers are only now starting to see shelf prices gradually decline, according to the March 28 Egg Markets Overview from the U.S. Department of Agriculture. In February, the average price of a dozen eggs came to $5.90.

“In the same way that just because the barrel price of oil goes down does not mean that gas prices immediately go down, there’s a delay here,” Thompson said. “Retailers get to choose their own price, and they took a lot of losses when prices were exceptionally high. They may be saying, ‘I’ve lost money over here, so I’m going to let what I have in stock go out at the price it currently is before I lower the price, to compensate for that earlier loss.’”

Thompson said that retailers often use eggs as a “loss leader,” meaning the product is sold at a price below its market cost to stimulate the sales of more expensive goods. She said that it serves as an incentive to bring that retail price back down.

However, with highly pathogenic avian influenza — or HPAI — still in the background and typically higher demand at Easter, there could be some price fluctuation.

“Eggs are a basic product that everybody puts in their basket, so I think there will be a pretty quick response to that,” Thompson said. “The only caveats to that are more cases of HPAI and the holiday demand. You’re going to have a little bit of extra demand for the holiday season, so you’re not necessarily going to see the prices go up, but you may see fewer eggs on the shelf. That might drive a little of the competition for those wholesale market eggs, which is eventually going to bump that price a little.”

Transportation and production input costs, including feed, can also impact the price of eggs, Thompson said.

“The cartons, the cleaners, all the things that are going into the inputs, we don’t necessarily manufacture in the United States, so with any disruption in trade there will likely be changes in cost of good, and some of those are going to affect the price of eggs or the price of inputs for those eggs,” Thomspon said.

The price of feed also goes into the cost of producing eggs, and Thompson said those change with corn and soybean prices, “so that has a whole commodity bend to it.”

Though the price of eggs is coming down, Thompson said the extent of the decline would be market-based.

“Some of the markets have been recovering,” she said. “They’ve already had new birds coming online and laying eggs again.

“Some markets are still hit pretty hard,” Thompson said. “I don’t think we’re going to see $1.99 eggs anytime soon, but I think that everybody is working really hard to get back to that.”

HPAI impact and recovery

The outbreak of HPAI in 2024 had a significant impact on the number of egg layers in the country. In 2024, 38 million layers were affected by the bird flu. An additional 30 million layers were affected in January and February 2025, impacting the total number of eggs that end up on grocery store shelves.

“Prior to the disease outbreak, we were producing about 8 billion eggs on a monthly basis,” Thompson said. “For February of 2025, we produced about 6.6 billion. From a scalability perspective, that’s why when people were talking about the high egg prices, it’s because we just don’t have the eggs.”

Thompson said that though the number of layers is still low, she is seeing those numbers coming back up.

“We see really high recovery and replenishment rates in eggs in incubators,” Thompson said. “It looks like the industry is doing an awful lot to try to bump up the number of birds as quickly as possible so that those egg numbers recover as quickly as possible.”

Forecast with massive rain may mean planting do-overs for Arkansas farmers

By Mary Hightower
U of Arkansas System Division of Agriculture
April 2, 2025

LITTLE ROCK — As forecasts call for up to 10 inches of rain through Sunday, the immediate future for Arkansas farmers will probably involve clearing ditches, with a good likelihood next week will be taken up with replanting and reworking fields, extension specialists said.

Planting of the state’s commodities has begun, with Monday’s Crop Progress report from the U.S. Department of Agriculture showing 22 percent of the state’s corn crop planting and 3 percent already emerged.  Rice was 8 percent planted and 1 percent emerged. Soybeans were 5 percent planted. Winter wheat, usually harvested in summer, was 11 percent headed.

While rain is usually a welcome event, the expected deluge can wash away plant beds and any newly emerged seedlings.

“I’ve been telling guys to hold off,” said Jeremy Ross, extension soybean agronomist for the University of Arkansas System Division of Agriculture.  “We’ll probably need to repull beds that have been freshly pulled.”

The National Weather Service issued a flood watch for much of the state through April 6.

“There’s not much you can do with that much rain in a short amount of time,” said Scott Stiles, extension economics program associate for the Division of Agriculture. “You want to have all the ditches and pipes open.”

In northeastern Arkansas, “everybody around here has water furrows run — a good effort on drainage,” Stiles said.

“Backing up of the rivers, streams and bayous will be the story,” said Jarrod Hardke, rice extension agronomist for the Division of Agriculture. “Low ground that’s already planted may be wiped out regardless of the crop planted there.”

Hardke said “rice will survive the best, but levees will be the issue. They’ll get washed out and blown and have to be repulled and reseeded.

“Recently planted corn and soybean are in for a wild ride for survival,” he said. “Cool temperatures may help buy them some time but staying flooded or saturated for four-plus days is a bad recipe for emerged seedlings and fresh planted seed.”

The cotton and peanut growers, with their later planting dates, might dodge a bullet.

“We haven’t begun to plant yet,” said Zachary Treadway, extension cotton and peanut agronomist for the Division of Agriculture. “If we end up getting all the rain they’re calling for, we could see delays, either from extremely wet ground that takes a long time to dry, and/or replants taking priority.

Crop insurance considerations

Stiles said that for crop insurance purposes April 1 is the earliest planting date for rice, with April 15 being the earliest planting date for soybeans.

“Rice or soybeans that have already been planted are not eligible for replant payments from crop insurance,” he said.

And they’re off! Crop planting is underway in Arkansas

By Mary Hightower
U of Arkansas System Division of Agriculture

LITTLE ROCK — Planting season is underway for Arkansas farmers, with corn growers first to getting seed in the ground, according to the Crop Progress report from the National Agricultural Statistics Service. 

The statistics service, part of the U.S. Department of Agriculture issues weekly crop progress and condition reports during the growing season.

Monday’s report showed Arkansas corn 2 percent planted, compared to 1 percent at this time last year and the 1 percent five-year average.

The report also said that 3 percent of the state’s winter wheat was forming grain heads. That compared to 1 percent at this time last year and to the zero percent five-year average. More than half of the winter wheat crop — 58 percent — was rated in good to excellent condition.

Corn

Jason Kelley, wheat and feed grains agronomist for the University of Arkansas System Division of Agriculture, said planting corn now is not unexpected.

“It's 80 degrees and it's dry and it's mid-March,” Kelley said. “It's hard to not plant something, but producers still have concerns about a potential late season cold snap, so up to date, planting has started slow but will be picking up speed as we near late March.”

In some years, corn planting may start on a very limited basis as early as late February in the southern tier of counties in Arkansas, but not this year due to wet weather.

“With corn, our planting date studies have shown there is a fairly wide window when we can maximize yields, generally up to late April, so planting early may be beneficial some years, but getting the optimum stand is what we are really shooting for,” Kelley said
“I think overall the acreage will be up this year,” he said. “2024 was a little bit of a down year as far as acreage with  500,000 acres. In 2023, we had about 750,000 acres.

Kelley said he expected 2025 to see “a little bit of a rebound” given a somewhat more optimistic outlook for corn prices than other commodities.

Rice

While corn was the only crop to make the report for planting, Jarrod Hardke, rice extension agronomist for the Division of Agriculture said there may have been two or three rice growers who got started last week.

This week, many rice growers were doing field prep, but “planting is beginning to pick up speed and by this coming weekend it will really be getting cranked up,” Hardke said.

Weather is a concern, with very low humidity and high winds. The March 14 storms that spawned deadly tornadoes, didn’t bring a lot of rain.

“Rains were variable with some growers receiving 1-2 inches while others may have technically gotten a little rainfall overnight, but by the morning they didn't know whether they had or not because it was so dry,” he said.

Red flag warnings covered most counties of the state on Wednesday, with wind advisories covering the rest. The next opportunity for rain would be on Sunday.

“That rain will be welcome to put a little moisture back to the soil and encourage a bigger start to planting,” Hardke said.

Soybeans

Jeremy Ross, extension soybean agronomist, said soybean planting was just getting started.

A lot of ground is ready to plant, but we didn’t see the February planting that we have seen the last two years due to rain events over the past month,” he said. “If the weather holds, we could have a significant portion of the soybean crop planted in the next few weeks. 

“I’m anticipating soybean acreage to be about what we have seen the past two years,” Ross said. “Our acreage should remain around the 3 million acres mark, but we could see some changes one way of the other depending on how planting progresses over the next two months. 

“We are just now getting into the early planting window for the southern part of the state, and we still have time to get the soybean crop planted to maximize yields,” he said.

Cotton and peanuts

“Both cotton and peanuts will start probably the third week of April,” said Zachary Treadway, extension agronomist for cotton and peanuts.

“If you're planting past the last day of May you've gone too late,” he said. “In a perfect world all of our planting will  come between April 20 and May 20 — that’s if the planting season is kind to us.”

“We have some issues last year where it was cool and rained and planting got dragged out and some planting got abandoned all together,” Treadway said.

Soil temperature is the cue for cotton growers to get seed in the ground. “They need a consistent 65 degrees at about four inches of soil depth, he said.

Treadway said that considering the market, he expects to see cotton acres decline slightly in Arkansas while peanut acres may increase.

Price and acreage rollercoaster

Scott Stiles, extension economics program associate, said the markets may do some reshaping of expected acres. USDA will issue its annual Prospective Plantings report on March 31, giving an overview of farmers’ intentions for the 2025 growing season.

Like Treadway, Stiles expected cotton acres to run lower.

The National Cotton Council “had Arkansas' cotton acres down 7 percent to 604,000,” Stiles said. “That’s not a surprise and some think cotton acres may be even lower than that. Cotton prices for the 2025 crop touched 70 cents last Friday and again Monday but didn't stay there long.

“With the heavy supply situation in cotton, there's little incentive today for it to encourage acres. With so much of the U.S. cotton crop grown in Texas, we may see some weather-related price improvement later in the growing season,” Stiles said.

Corn and soybean prices peaked around February 20th, but “unfortunately, both of those have run out of gas,” Stiles said. There was quick run-up in rice last week, but that rally fell flat too.

“Corn is about 40 cents off its February highs and soybean about 60 cents off its highs,” he said.Since making a recent top March 11, new crop rice futures have pulled back about 23 cents per bushel. The commodities are nervously watching all the global trade dynamics and trying to figure it all out.

“Seasonally, we generally see prices for corn and soybeans work higher through planting and oftentimes peaking by mid-June if crop conditions are favorable,” Stiles said.

If there's any good news to report, it's probably the pullback in diesel prices. 

“Diesel futures are trading around $2.20 today and that's 45 cents off the January high,” Stiles said on Wednesday. “It’s a little relief there as field work gets underway.”

USDA announces $10 billion for farmers amidst economic hardship, uncertainty

By Sarah Cato
U of A System Division of Agriculture

LITTLE ROCK – As farmers face high input costs, low commodity prices and a postponed farm bill, the USDA is issuing up to $10 billion in direct economic assistance to agricultural producers.

PRODUCERS STRUGGLING – With low commodity prices and high input costs, Scott Stiles said the recent funding issued by the USDA is much needed assistance for Arkansas producers. (Division of Agriculture photo.)

The Emergency Commodity Assistance Program, authorized by the American Relief Act of 2025, will provide payments to growers based on planted and prevented planted crop acres for eligible commodities for the 2024 crop year. Major Arkansas row crops that qualify include corn, soybeans, cotton, rice, peanuts and wheat.

“This assistance is greatly appreciated by growers and no doubt, they need all the help they can get,” said Scott Stiles, an extension economics program associate for the University of Arkansas System Division of Agriculture. “The last few years have resulted in the most difficult economic situation that we’ve seen in the state since the mid-1980’s.

“In the background, we have now reached the third year without an updated farm bill,” Stiles said. “Arguably, you could say we’ve been operating under the same farm program provisions for the past 10 years. Persistently high input costs and a deep correction in commodity prices has producers in the state struggling. This is evidenced by the sheer number of operations that have gone out of business in the past two years.”

In order to streamline and simplify the delivery of ECAP funding, USDA’s Farm Service Agency will begin sending out pre-filled applications to producers who submitted acreage reports for 2024 eligible ECAP commodities soon after the signup period opens on March 19. Producers do not have to wait for their pre-filled ECAP application to apply, but can visit the FSA website. Stiles provides more information on eligibility, payment amounts and the application process in his most recent blog post.

“The assistance from ECAP will help, but a much improved and modernized farm policy safety net is needed for producers,” Stiles said. “Hopefully we will see some progress on that front in 2025.”

April 14 workshop aims to help Arkansans plan to keep the farm in the family

By Ryan McGeeney
U of A System Division of Agriculture 

SEARCY, Ark. — Keeping the family farm in the family can be more complicated than many realize. The University of Arkansas System Division of Agriculture is working to help farm families and other interested Arkansans plan for the inevitable with a second succession planning meeting on April 14.

MAKE A PLAN — The University of Arkansas System Division of Agriculture is working to help farm families and other interested Arkansans plan for the inevitable with a second succession planning meeting on April 14. (Division of Agriculture graphic.)

Sherri Sanders, White County agriculture extension agent for the Division of Agriculture, said reaction to the first session, held Feb. 25, helped shape the upcoming meeting agenda.

“Our first session got the conversation started,” Sanders said. “It’s emotional, it’s hard. You’re coming to terms with your death or retirement from your farm that’s been in the family for generations. Most people just don’t talk about it, and they think they’re OK because they’ve got a will — but a will isn’t a succession plan. It doesn’t lay out who gets what, or how the farm will be run.

“This second session is still for farmers and ranchers, but the information can really apply to anybody who wants to plan for their estate,” she said. “Because estate taxes, power of attorney and living wills affect everybody.”

Rusty Rumley, senior staff attorney for the National Agricultural Law Center in Fayetteville, Arkansas, will be the meeting’s featured speaker.

“People know they need to find an attorney, but they don’t know what to be prepared for at that first meeting,” Sanders said, noting that attorneys typically charge by the hour. “Rusty will help them understand how to prepare to meet with that attorney.”

The session will take place at 6 p.m. at the White County Extension Office, located at 2400 Old Searcy Landing Road in Searcy, Arkansas. The cost to attend is $25 per person, which includes dinner.

The deadline to register online is April 7.

Economists tackle estimating consumer effects following the loss of billions of birds and eggs lost to avian influenza

By Mary Hightower
U of Arkansas System Division of Agriculture

FAYETTEVILLE, Ark. — Fewer and more expensive eggs in 2024 put estimated $1.41 billion burden on consumers in 2024, according to study by a trio of researchers examining the impact of highly pathogenic avian influenza — HPAI — on the economy.

Expectations are for the price burden to continue through 2025 as producers work to repopulate laying hens lost to HPAI.

The study, “The Economic Impact of HPAI on U.S. Egg Consumers: Estimating a $1.41 Billion Loss in Consumer Surplus” was published last month by the Fryar Price Risk Management Center. It was conducted as an extension to an earlier paper, “Biological lags and market dynamics in vertically coordinated food supply chains: HPAI impacts on U.S. egg prices,” published in the journal Food Policy in 2024.

The Fryar Center is part of the University of Arkansas System Division of Agriculture and the Dale Bumpers College of Agricultural, Food and Life Sciences.

James Mitchell, assistant professor and extension economist for the Division of Agriculture, was the lead author on both papers, which were written with Jada Thompson, associate professor and Division of Agriculture economist and Trey Malone, an economist formerly at the University of Arkansas, but now at Purdue University.

According to the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service, HPAI affected 38.4 million commercial egg laying birds and 29 flocks in 2024.

“As a result, we estimate an average week-to-week increase of 9 percent in retail egg prices, independent of other sources of egg price inflation,” the authors said. Using own-price elasticities — a measure of demand responsiveness to price changes — they estimated that price increases lowered demand for eggs by 2 percent on average.

“This reduction in consumption, coupled with higher prices, led to an estimated consumer surplus loss of $1.41 billion,” the researchers said. “This estimate reflects the economic burden on consumers due to reduced availability and affordability of eggs following HPAI outbreaks.

“The magnitude of these losses underscores the importance of understanding how disease outbreaks in the egg supply chain influence consumer welfare and market dynamics,” the three authors said.

The cost of eggs

While the cost of eggs may seem to be a simple supply vs. demand equation, determining the size of the economic loss is quite a bit more complex, say the economists.

“Someone not familiar with broiler or turkey or egg production might say, ‘oh, a bird died today because of bird flu and egg prices today are impacted by that’,” Mitchell said.

HPAI has been hitting broilers, egg layers and turkey production in the U.S. and globally hard since 2022, resulting in the loss of billions of commercial birds, not to mention birds and other animals in the wild.

“Our main thesis is that you have to consider a longer timeframe,” Mitchell said. “What’s happening today is a function of what happened six months ago.”

Because of the fierceness of the current strain of HPAI, which has a mortality rate of higher than 75 percent, whole flocks are destroyed once the disease is detected. Mitchell said if a flock has to be depopulated because of avian influenza or another cause, “you’re losing egg production from that flock.

“But you don’t just replace that flock tomorrow. It takes about six months for the new birds to reach maturity and start laying eggs,” he said.

Mitchell said that when they started their initial analysis looking at 2022 data, the challenge was “how much consideration had to be given to disentangling the impacts of bird flu from other things that were happening in 2022.”

Economic aftershocks from the COVID pandemic and the Ukraine war and resulting higher grain prices “were something we had to be careful about,” he said.

Price rollercoaster

When egg prices rise, so do the number of media interview requests for Thompson.

“The questions that are asked right now are, ‘Why are prices are high?’ And ‘when are they coming back down?’” Thompson said. She noted that in 2022, HPAI led to some 43 million laying hens being taken out of egg production” in the U.S.


That was possibly the largest loss of layers in one quarter, at least until 2024-25.

“In the fourth quarter of 2024, there was a loss of 20 million birds,” Thompson said. “And in the first two months of this year, some 30 million birds. That’s an astronomical number of birds being affected by HPAI.”

Much of the nation’s commercial egg production is concentrated in a fairly small area, including Minnesota and Iowa, Mitchell said.

There have been proposals within the industry to bring broiler eggs to the market, but both Thompson and Mitchell say that’s not an easy fix because the broiler and egg production systems don’t interact.

“It’s not the first time we’ve had this conversation,” Thompson said. “There are limitations on what can be done when dealing with a different system. How do we collect these eggs? How are we going to store and clean them? This will mean additional transportation costs.

“And egg prices are really high already,” she said. According to the Bureau of Labor Statistics retail egg prices reached $4.95 per dozen in January 2025, an increase of 96 percent compared to January 2024.

The research comes with a few important caveats. First, the estimate assumes that consumer preferences and purchasing behavior remained stable, meaning that consumers responded to price increases in the same way as they have in the past.

Second, the analysis focuses on the direct impact of HPAI on egg prices and consumer surplus, meaning it does not account for any indirect effects, such as potential changes in producer behavior or government policy responses.

“Despite these considerations, this estimate provides a clear and useful benchmark for understanding how HPAI affected egg prices and consumer spending in 2024,” the authors said.

Growth rates of broilers contribute to behavior differences, shed light on welfare impacts

By Maddie Johnson
University of Arkansas System Division of Agriculture
Arkansas Agricultural Experiment Station

FAYETTEVILLE, Ark. — As poultry companies weigh cost and efficiency with higher animal welfare standards, research comparing conventional and slow-growing broiler breeds showed that the slow-growing chickens displayed behaviors more closely associated with positive welfare.

Broilers — chickens specifically bred for meat production — are typically raised for six to eight weeks, while slow-growing broilers need up to 12 weeks to reach maturity.

AN EYE FOR WELFARE — Rosie Whittle, a poultry science postdoctoral fellow with the Center for Animal Food Wellbeing and the Dale Bumpers College of Agricultural, Life, and Food Sciences, worked on a study examining conventional and slow-growing broilers by tracking their behaviors to see how they exhibit positive welfare. (Image courtesy of Rosie Whittle)

Though gaining popularity in some European markets, slow-growing broilers have not seen the same market expansion in the United States, as they take longer to reach market weight than conventional broilers.

“The economic impact to the broiler industry raises the question: 'Why would you want to use a broiler that is going to eat more food, grow slower, and cost more to produce?'” said Rosie Whittle, poultry science postdoctoral fellow with the Center for Food Animal Wellbeing and the Dale Bumpers College of Agricultural, Food and Life Sciences at the University of Arkansas.

Whittle, alongside Shawna Weimer, assistant professor of poultry science and director of the Center for Food Animal Wellbeing, set out to explore this question facing industry leaders who are weighing the choice of conventional versus slow-growing broilers.

Weimer conducts research for the Arkansas Agricultural Experiment Station, part of the University of Arkansas System Division of Agriculture. The Center for Food Animal Wellbeing is a unit of the Division of Agriculture.

Their work explored the impacts of genetic strain, stocking density, and, most importantly, the comparison of physiological versus chronological age between the two genetic strains on broiler behavior. Genetic strain, or the specific breed of chicken, defines whether broilers are conventional or slow growing. Stocking density represents the number of birds in a specific area.

Researchers reviewed video recordings of the birds at specified intervals to track behaviors, such as walking, standing, and preening, which are signs of positive animal welfare. Preening is when a bird uses its beak to clean its feathers.

Their study, “Effects of genetic strain, stocking density, and age on broiler behavior,” was published in Poultry Science, an official journal of the Poultry Science Association.

Results of the study revealed that a larger percentage of slow-growing broilers were observed standing, walking, and preening, while more conventional broilers sat in a lateral posture. The effects of stocking density were minimal, so the number of birds in an area did not have a significant impact on broiler behavior.

Detailing bird behavior

LOOKING FORWARD — Shawna Weimer, assistant professor of poultry science and director of the Center for Food Animal Wellbeing, served as corresponding author of the study and said she would like to see further research on a larger scale to examine what other factors could affect animal welfare. (University of Arkansas System Division of Agriculture photo)

Weimer pointed out that “animal welfare is quite dynamic” and emphasized that further investigations of broiler behavior should be undertaken. Whittle also stressed that their research was focused on understanding the effects of growth rate on broiler behavior, not necessarily what is best for companies or consumers.

Whittle also noted that the study focused on two types of broilers, but “all genetics companies have a different recipe for chickens.” Therefore, in tracking behavior, it is important to be aware of the possibility that “one genetic strain of broiler behaves completely different to the other,” she said.

Whittle said further research is required because “it’s always important to expand so we’re not just generalizing based on two specific genotypes.”

Co-authors of the work included Darrin Karcher and Marisa Erasmus, both associate professors of animal sciences at Purdue University. Weimer serves as corresponding author, meaning she is responsible for communication and questions about the publication.

The project was supported by Purdue University’s Department of Animal Sciences and the Center for Food Animal Wellbeing. The animal care staff at Purdue University’s Poultry Unit, Olivia Walton, Heidi Rinehart, and Nathan Griffith also contributed to the work.

LITTLE ROCK — For Arkansas Master Gardeners, it’s important to support the next generation of leaders in plant science. As part of this effort, the program funds the Janet B. Carson High School Senior Scholarship, which is now accepting applications from Arkansas students.

PLANTING THE FUTURE — Arkansas Master Gardeners are accepting applications for the Janet B. Carson High School Senior Scholarship, which is available for Arkansas students who plan to attend a state college or university and pursue a plant science-related degree. (Division of Agriculture graphic.)

The $2,000 scholarship is available to Arkansas high school seniors who plan to attend an Arkansas college or university. The student must be planning to pursue a degree in a plant science-related field, including horticulture, botany, agronomy, forestry and landscape architecture and design.

Randy Forst, extension consumer horticulture educator and Master Gardener program coordinator for the University of Arkansas System Division of Agriculture, said the scholarship is a fitting tribute to its namesake.

“Janet Carson spent 38 years sharing her knowledge and passion for gardening with thousands of people around the state as a horticulturist for the Cooperative Extension Service,” Forst said. “The Janet B. Carson Scholarship was set up in 2014 in honor of her significant contributions to the field of horticulture in Arkansas.

“As Master Gardeners, we hope that this opportunity will encourage more young people to pursue a career involving plants,” Forst said. “Investing in the future of the plant industry is fundamental to our mission.”

The deadline to apply for the scholarship is March 14. The application is available at uada.formstack.com/forms/jbc_high_school_scholarship. Scholarship applicants must submit a statement about their interest in plant science and their career goals, two letters of recommendation, and their high school transcript and ACT scores. All applications must be submitted online.

‘Beyond the Fence’ Lunch and Learn to highlight herd rebuilding, cattle markets

By Sarah Cato
U of A System Division of Agriculture

LITTLE ROCK – With the national beef cow herd at its lowest level since the 1960s, an upcoming lunch and learn session will focus on herd rebuilding strategies and current cattle markets.

FAYETTEVILLE, Ark. — The same substance that paints the sky with the Northern Lights also appears to enhance plant growth and insect defense, according to a new study.

Food science and entomology researchers from the Arkansas Agricultural Experiment Station teamed up to harness plasma and measure its effects on rice seed. The project began after Mahfuzur Rahman, assistant professor of food science, acquired a machine that produces cold plasma.

Known as the fourth state of matter, plasma is an electrically charged gas that has fluid-like behavior. Rahman points to the Northern Lights as the most familiar example of cold plasma, which means it is considered low temperature compared to the much higher temperatures of plasma in stars. Other examples of cold plasma like that generated in Rahman’s lab include fluorescent lights and neon signs.

Rupesh Kariyat, associate professor of crop entomology, became interested in investigating cold plasma’s effects from an insect perspective — an area he said had not been studied adequately.

“I thought it would be a good idea that we expose our seeds to cold plasma and then grow those seeds out into plants and ask the question of whether the plants are doing better,” Kariyat said.

“If this works, then we can come up with a method to expand at a scale where we can add cold plasma to complement existing seed treatments to boost their growth and defense against insect herbivores,” Kariyat said, noting the potential to reduce insecticide use.

One of Kariyat’s graduate students, Deepak Dilip, led the project in collaboration with Nikitha Modupalli, a postdoctoral fellow in food science and member of Rahman’s lab. Their study, "Atmospheric cold plasma alters plant traits and negatively affects the growth and development of fall armyworm in rice," was published in Nature's Scientific Reports in January.

Dilip served as the lead author, with Modupalli, Rahman and Kariyat serving as co-authors. Both Rahman and Kariyat are researchers with the Arkansas Agricultural Experiment Station, the research arm of the University of Arkansas System Division of Agriculture.

Tracking seed germination and plant growth

The study specifically investigated rice plant defense against fall armyworm. Seeds were treated with cold plasma and then irrigated with cold plasma-activated water, which is water that has been treated with cold plasma and has some antimicrobial properties. The plasma interacts with water molecules to generate highly reactive molecules containing oxygen and nitrogen, which effectively kill bacteria.

The results revealed that rice seeds treated with cold plasma could negatively impact fall armyworms’ growth and development.

Researchers also observed signs of improved plant growth such as more leaf growth. They also saw a faster germination rate in cold plasma-treated plants, though this was not statistically significant. It has been found that cold plasma can increase germination by eroding a seed’s surface.

Additionally, though germination rates were quicker, control plants eventually caught up with treated ones in terms of growth, making final germination counts similar between untreated and cold plasma-treated seeds. Researchers point out that this suggests cold plasma applications, though they can benefit initial plant growth, would not be as beneficial in later stages of the plant’s growth cycle.

As for the study’s impacts on the future, Kariyat and Rahman hope to apply cold plasma to the field of organic food production.

Rahman explained that the U.S. Department of Agriculture is evaluating cold plasma as an organic technology, potentially paving the way to alternatives for pesticides.

“In the future, if we can optimize this technology for organic production, it will create a very new avenue for organic food growth,” Rahman said.

HOPE, Ark. — Amanda Greer is being remembered for her love of family, science and a good insect meme. By Mary Hightower. 780 words. With portrait of Greer, file photo

Greer, born in Warren, passed away Feb. 19 following a battle with cancer.

Agriculture was her life. She farmed and worked as a cotton scout and crop consultant in the 1990s. In 2006, she joined the University of Arkansas System Division of Agriculture as a Chicot County extension agent, moving later to Lafayette County, first as an agent, then as staff chair. Between her time in Chicot and Lafayette counties, Greer also worked as a program technician at the former Southeast Research and Extension Center in Monticello.

In 2018, she started as lab manager for the Arkansas Nematode Diagnostic Lab, based at the Southwest Research and Extension Center in Hope.

Kim Rowe, Hempstead County extension agent, knew Greer for two decades and said she looked to Greer for her expertise in weed identification, plant diseases, and insect and nematode problems.

“She was always patient with me busting up in her lab,” Rowe said. “She would confidently solve any mystery, no matter how much time it took.

“While I will certainly miss her mentorship and assistance professionally, mostly I will miss my friend who loved quality insect memes, photos of lichens, and trying exotic foods,” Rowe said.

Daniel Rivera, director of the Southwest Research and Extension Center, said Greer was a private person, but could be gregarious once she got to know someone.

“She was warm, witty, funny, generous with her time, and thoroughly enjoyed working in the nematode lab,” Rivera said. “She always took time to educate me about nematodes, and she was that way with anyone who came to visit the lab. From kids to state senators, all were taught equally! Her eyes would light up when they would find out something new or neat. She just loved the science.

“She felt a responsibility to ag producers, the Division of Agriculture, and the lab, and took great pride in the work the lab put out,” Rivera added. “Amanda was the living embodiment of our core values.” 

Rivera said Greer would also light up when she spoke of her daughter, and “Amanda loved talking about Dakota's accomplishments.”

Greer was also a diehard Razorback fan who loved to go to the games with her husband, William, and daughter Dakota.

“From my friend Amanda, we can take one final lesson: to be strong, steadfast in your tasks, and ensure that you spend time and enjoy the ones you love as much as you can,” Rivera said.

Terry Kirkpatrick, who oversaw the nematode lab before retiring and recommended Greer for the job, having been her adviser through her master’s studies and had seen her at work as an extension agent.

Her success as an extension educator was because “she was a teacher at heart,” Kirkpatrick said. “It took her about 15 minutes to win over the farmers in Lafayette County, because she was out there with them.

“She might show up at suppertime on a Friday night at a farmer’s house and say, ‘I just walked through your rice field and you’ve got blast and you probably need to think about spraying that first of next week’,” Kirkpatrick said. “She was just Johnny-on-the-spot and she’d take them out there to look for blast or root knot nematodes, or whatever the disease of the week was.”

“Quietly and not in the headlines, she had a significant impact through all the things she did,” Kirkpatrick said.

Ken Korth, head of the entomology and plant pathology department for the Dale Bumpers College of Agricultural, Food and Life Sciences and the Division of Agriculture, said “we were so fortunate that Amanda was able to take on the leadership position at the nematode diagnostic lab. 

“Her expertise and approach made her an outstanding diagnostician. I think her strong performance truly benefited from a broad background in agriculture, having served as a county agent and working on the family farm,” Korth said. “Amanda earned her master’s degree in our department working under the direction of Dr. Terry Kirkpatrick. It was especially enjoyable to have one of our alumni back working as a colleague.” 

Jerri Dew, Lafayette County extension staff chair, said that Greer was highly respected in the row crop community.

“Many Lafayette County farmers still had close ties to her and consulted with her regularly,” Dew said. “When I came to work in Lafayette County, Amanda helped me more than any other person in extension. She is going to be sorely missed by a lot of people.”

Greer is survived by her husband of 22 years, William "Shotgun” Greer, and daughter, Dakota Greer.

A visitation and funeral service were held in Lake Village.

Cooperative Extension Service University Center launches new Labor Market Observatory tool

By Rebekah Hall
U of A System Division of Agriculture

LITTLE ROCK — The Cooperative Extension Service has released a new data tool providing access to workforce indicators across the state.

The Labor Market Observatory provides data from each of the state’s eight economic development districts. The new tool is a product of extension’s Community, Professional and Economic Development department. In the fall of 2023, the department received funding from the U.S. Economic Development Administration’s University Center Program to create the Center for Rural Resilience and Workforce Development. The center worked in partnership with Heartland Forward to develop the LMO.

“The Labor Market Observatory is a visual representation of workforce and demographic metrics for the state of Arkansas,” said Brandon L. Mathews, extension program associate for economic development for the University of Arkansas System Division of Agriculture.

ECONOMIC DEVELOPMENT — A new data tool, created in partnership by the Cooperative Extension Service and Heartland Forward, provides access to workforce indicators from each of Arkansas' eight economic development districts, which are funded by the U.S. Economic Development Administration. (Division of Agriculture graphic.) 

Mathews said the tool is designed to help development professionals, community organizations and individuals access workforce indicators from state and federal sources. These indicators include demographic information — such as the share of Hispanic, Marshallese, and rural and urban populations — as well as housing, income and employment statistics at the county, development district and state level.

Arkansas is divided into eight economic development districts that are funded in part by the U.S. Economic Development Administration. These districts offer a range of services for their communities, including grant writing, planning, and community and economic development.

“Economic development districts were the primary audience in developing the LMO tool,” Mathews said. “However, economic developers, city and county officials, chambers of commerce and the general public will be able to access the LMO. The goal of this tool is to provide workforce information to help communities make informed decisions based on key data, while also making the information easier to understand.”

Mathews said that when a development professional from one of the districts wants to calculate housing costs and income for a region and compare it to the whole state, for example, the LMO tool will retrieve the relevant data and calculate totals, rather than the individual having to compile data from several sources.

“All of that work is done for them through the LMO, automatically saving them time and resources,” he said.

Mathews said the LMO is intended to help the state’s economic and workforce practitioners make smart choices that “support workforce and human capital projects that are good for Arkansans.”

Help for Arkansans

Each economic development district is required to develop a data-driven plan that is specific to the needs and opportunities of their community. Mathews said the LMO can help these regions measure success in reaching their strategic goals.

“As LMO data and features are added over time,” Mathews said, “the hope is that the Cooperative Extension Service will become a trusted and reliable source for workforce data.”

Hunter Goodman, assistant professor and extension director of the Center for Rural Resilience and Workforce Development, said the LMO is key to the center’s mission.

“The data dashboards are an important component of our mission to equip Arkansans with sustainable, accessible, research-based practices and expertise to create vibrant, self-reliant communities where businesses, organizations and families thrive,” Goodman said.

The LMO was developed in partnership with Heartland Forward, a Bentonville-based organization dedicated to advancing economic success in the middle of the country, with three core impact areas: regional competitiveness, talent pipeline and health and wellness. Heartland Forward led the creation of the visualization dashboard.

“We’re excited to roll out the dashboards and honored to serve as a trusted resource for this project,” said Rodrigo Ramirez-Perez, a research analyst at Heartland Forward. “By making data more accessible and approachable for development professionals, community organizations and individuals alike, we believe they can strengthen their communities through strategies informed by data-driven insights.”

Mathews said more workforce data will be added to the LMO in the coming months, with plans to provide data at the city or zip code level where available. The University Center plans to host a series of trainings on how to use the LMO, which will soon be added to the University of Arkansas System Division of Agriculture calendar. Event postings will also be shared on the Division of Agriculture’s Community and Economic Development Facebook page.

Machine learning maps animal feeding operations to improve sustainability

FAYETTEVILLE, Ark. — Understanding where farm animals are raised is crucial for managing their environmental impacts and developing technological solutions, but gaps in data often make it challenging to get the full picture.

Becca Muenich, biological and agricultural engineering researcher, set out to fill the gap with a new technique for mapping animal feeding operations.

Without proper control strategies, the waste generated by these operations can pose significant ecological harm, Muenich said, such as surface water contamination with excess phosphorus and nitrogen. Animal feeding operations are defined as facilities that feed animals for at least 45 days per year in a confined area that does not grow grass or forage. For Muenich, a water quality engineer who focuses on how water moves through landscapes and how it can pollute areas by picking up and moving toxic materials, this issue piqued her interest.

“We can’t really address something if we don’t know where the problem is,” said Muenich, an associate professor with the College of Engineering at the University of Arkansas and researcher for the Arkansas Agricultural Experiment Station, the research arm of the University of Arkansas System Division of Agriculture.

“We don’t have a good nationwide — even at many state levels — understanding of where livestock are in the landscape, which really hinders our ability to do some of the studies that I was interested in,” she said.

Muenich said there has been a rise in these feeding operations in response to increasing population size and global demand for livestock products.

Considering key predictors of feeding operation presence such as surface temperature, phosphorus levels and surrounding vegetation, Muenich’s team built a machine learning model that can predict the location of feeding operation locations without using aerial images. Machine learning models are a type of computer program that can use algorithms to make predictions based on data patterns.

The model was developed using data encompassing 18 U.S. states. The data was broken up into individual parcels based on ownership. Testing against a dataset of known animal feeding operations, the model predicted their location with 87 percent accuracy.

The study, “Machine learning-based identification of animal feeding operations in the United States on a parcel-scale,” was published in Science of the Total Environment in January.

Filling in the gaps

Previous attempts at identifying animal feeding operations have often relied on aerial images, Muenich said, but livestock facilities often look different between states and by animal, so she and her team aimed to employ further strategies.

She explained the lack of understanding surrounding livestock locations often comes from differences in how states interpret the Clean Water Act, which requires farms classified as “concentrated animal feeding operations” to get permits through the National Pollutant Discharge Elimination System. These facilities are a type of animal feeding operation with more than 1,000 animal units.

Despite the national regulation, states administer this permitting differently, leading to differences in available data.

For example, Muenich built a watershed model in an area with of Michigan and Ohio that included multiple feeding operations. Data was readily available through the pollutant elimination system for Michigan due to the state’s permitting requirements. The same data, however, wasn’t available for the same operations in Ohio, which set Muenich down this path of investigation.

Advancing towards a better accounting of livestock can help with developing strategies that can improve environmental outcomes of livestock management while creating economic opportunities for farmers through the scaling up of technologies aimed at combating animal waste, Muenich said. Scaling these technologies in economically feasible ways requires knowledge of where livestock are most prevalent and spatially connected, she explained.

Co-authors of the study included Arghajeet Saha, formerly a postdoctoral researcher at the University of Arkansas and currently an assistant scientist with the Kansas Geological Survey; Barira Rashid, Ph.D. student at the University of Arkansas; Ting Liu, a research associate with the University of Arkansas biological and agricultural engineering department; and Lorrayne Miralha, an assistant professor with The Ohio State University’s department of food, agricultural and biological engineering.

The research was supported by the Science and Technologies for Phosphorus Sustainability Center under National Science Foundation award number CBET-2019435. The Data with Purpose program from Regrid, a source for nationwide land parcel data, provided data used in the research.
