Beyond Amber Waves: Oklahoma State Introduces High-Antioxidant Purple Wheat to Cater to Consumers

Fri, 08 May 2026 18:53:58 GMT

The “amber waves of grain” are a patriotic staple of the American summer, painting a familiar slice of Americana across the horizon. While rolling fields of hard red winter wheat have long defined the landscape of the Plains, researchers at Oklahoma State University (OSU) are beginning to change that picture with a wheat variety that is anything but ordinary.

Known as OSU P92, this variety stands out for its deep purple hue and its potential to revolutionize the nutritional profile of staple foods.

A Class of Its Own

For decades, Oklahoma’s wheat industry has been built on hard red winter wheat and the occasional hard white variety. However, according to Brett Carver, Professor of Plant and Soil Sciences at OSU, their latest development represents a departure from the status quo.

“This is not just any other new wheat variety,” Carver explains. “It’s very different. We normally talk about hard red winter wheat... but this is not either one of those. This is a class we don’t even have.”

While the crop may grow and behave like the hard red winter wheat farmers are used to, it is actually a new innovation known as “purple wheat.” The grain boasts a deep purple hue on its outer layer, but the real breakthrough lies beneath the surface.

The Science Behind the Color

The unique appearance of OSU P92 is driven by anthocyanins, which is the same class of phenolics that provide the vibrant colors in blueberries, blackberries, black beans, and peppers. By bringing these compounds into a grain staple, OSU is bridging the gap between traditional row crops and high-antioxidant superfoods.

“Those colors come from a compound called anthocyanins,” says Carver. “So this purple wheat has those anthocyanins that would be present in common fruits and vegetables. That benefit we get from eating the fruits and vegetables also come now through the wheat.”

Breeding for the Real World

Creating a nutritionally superior grain is one thing, but making it viable for a commercial farm is another. The development process was far from simple. Researchers had to breed a variety that could handle Oklahoma’s volatile climate, resist local diseases, and still deliver the strong yields that keep farmers profitable.

To achieve this, Carver’s team had to look beyond traditional plant breeding. “Doing all these extra things meant we had to branch out a little bit because we just don’t have the expertise to measure phytochemicals,” Carver says.

The team leaned heavily on the expertise of OSU’s Nutritional Science Department. Notably, Carver credits a student researcher for driving the project forward, stating that her findings directly influenced the decision on how to advance the variety.

Stability from Field to Table

One of the biggest hurdles in developing purple wheat was ensuring the color, and the nutrients they bred into the wheat, lasted. Anthocyanins are notoriously unstable, but the team eventually selected a line that maintained its integrity.

“To maximize the color at harvest, we want to make sure we have that deep color that persists,” Carver notes. “With these compounds, they aren’t the most stable. But with this one, it’s one of our more stable colors.”

What’s in the Name?

While the variety is groundbreaking, its name remains humble: OSU P92. The “P” stands for purple, and “92" was its experimental selection number. Carver says the goal wasn’t to have a flashy name, but to let the performance and the final products—like breads and tortillas—take center stage.

If OSU P92 delivers on its promise of high performance and enhanced nutrition, it could do more than just change the color of the fields; it could redefine what farmers grow to meet the demands of health-conscious consumers.

Soil Test Results Offer ‘News You Can Use’ Beyond pH

Tue, 17 Mar 2026 16:44:43 GMT

When farmers talk about their soil test results, the conversation often starts and ends with soil pH.

While that one number is important to determining whether lime is needed, that insight is just a fraction of what’s available in the lab report, says Lizzie French, soil biology manager with Waypoint Analytical, a national soil testing lab that partners with Nutrien Ag Solutions.

At a time when fertility is one of the most expensive lines on a crop budget, she believes farmers are overlooking an opportunity to pull more data from soil test results into their everyday decisions.

“We know folks who get their testing done on a regular basis, and the only piece of it they use is the pH,” French says. “That’s important, but don’t overlook the rest of the results.”

From Paperwork To Management Tool

French says the first shift farmers often need to make is mental – to stop seeing the soil test as paperwork and start treating it as a management tool.

She encourages farmers to sit down with their agronomist, retailer or consultant and walk through the entire soil test report. Some of the specific areas to address in the discussion:

Where are phosphorus (P) and potassium (K) consistently low or high?
How do those nutrient levels line up with yield history?
Are problem spots in a field reflected in the soil test data?

“That conversation is where you start turning the report into a map,” French says — a map that can guide where to invest fertilizer dollars as well as where management practices might need to change.

Establish The Baseline

French doesn’t downplay pH; she calls it the essential baseline. In the Midwest, deep soils and high organic matter can sometimes mask underlying issues.

“Before you try to do anything else on that field, you’ve got to fix pH,” she notes. But once that is accomplished, she urges farmers to dig into information on:

Macronutrients: Determine if you are in a “build, maintain, or drawdown” mode.
Micronutrients: Identify elements that may help explain why high-fertility fields are underperforming.
CEC and Organic Matter: These offer clues on how well a soil holds nutrients and water, and how aggressively the land can be pushed.

Understanding the Chemistry

The “how” behind the numbers matters, too. Waypoint typically uses the Mehlich-3 extraction method for Midwest samples, French says, because it is well-validated and provides a quick turnaround.

However, other tests are also relevant depending on the region. Dan Kaiser, Extension nutrient management specialist at the University of Minnesota, highlights Bray P-1 and Olsen:

Bray-P1: Best for predicting yield response to P in slightly alkaline to highly acidic soils (pH of 7.4 or less), Kaiser says.
Olsen: The “gold standard” for soils with a pH of 7.4 or greater, though it can be used down to a pH of 6.0.

“Many labs using the Bray-P1 or Olsen tests will run the Olsen test at a certain pH automatically,” Kaiser says. He recommends using labs close to your farm and familiar with your soil type to ensure you get the best management advice.

The Biological Frontier

Beyond traditional chemistry, French is seeing more farmer interest in soil biology—getting a holistic view of what is living in the soil and how it affects nutrient cycling.

Waypoint’s soil biology tests help answer questions that traditional chemistry might miss, such as:

Are poorly drained zones losing nitrogen through denitrification?
Is there enough biological activity to release nutrients tied up in organic matter?
Are beneficial mycorrhizal fungi active?

“They’re farming microbes, whether they are aware of it or not,” French says of growers. “They’ve always been there, and they’ll continue to be a part of that growing system.”

Understanding that microbial workforce in soils, she says, can make every dollar spent on fertilizer work harder.

For farmers looking to get more from soil tests, one of the keys is connecting that biology back to management practices and product use such as:

Reduced tillage – “If you till, you’re going to break up those fungal networks,” she says. Less disturbance helps keep the “house” intact.
Residue management and cover – Keeping soil covered and adding organic inputs, whether through manure, cover crops or residues, feeds both microbes and fungi.
Targeted products – In some cases, she says, certain humic acid products appear to help “facilitate the conversation” between roots and fungi, though results depend on the product and the system.

Biology tests can show whether these practices and products are making a difference over time — moving the discussion from theory to measurable change.

Putting The Data Into Action

French is quick to point out that farmers don’t need to become microbiologists to get more practical information from soil testing. But they do need to ask more of their reports — and of the people who work with them.

“A lot of it’s logistical,” she says of the questions she routinely hears from farmers. “‘Can you work within what I’m already doing? Can you make recommendations? Can you work with this program I’m using for data?’”

Underneath those logistics is a bigger opportunity: using the full soil test report to shape decisions about where to spend, where to save and how to build long-term soil health.

For farmers already spending the money to sample their fields, French’s message is straightforward: don’t let that investment end with addressing only pH. The rest of the numbers are there, she adds, waiting to be turned into “news you can use” on every acre.

New Dietary Guidelines Move Food Pyramid Closer to the Farm

Wed, 07 Jan 2026 20:43:23 GMT

The White House delivered a simple but clear message to Americans today: Eat real food.

“We are finally putting real food back at the center of the American diet. Real food that nourishes the body, restores health, fuels energy and builds strength,” says Secretary of Agriculture Brooke Rollins. “This pivot also leans into the abundant, affordable and healthy food supply already available from America’s incredible farmers and ranchers. By making milk, raising cattle and growing wholesome fruits, vegetables and grains, they hold the key to solving our national health crisis.”

In the “most significant reset of federal nutrition policy in decades,” the White House released the Dietary Guidelines for Americans, 2025–2030 . The updated pyramid inverts the 1992 USDA version by prioritizing:

Protein (1.2 to 1.6 grams of protein per kilogram of body weight per day, an increase from 0.8 grams)
Dairy and healthy fats as the foundation
Vegetables (3 servings per day)
Fruits (2 servings per day)

Unlike the old pyramid’s grain-heavy base and processed carbs, new recommendations limit whole grains to 2 to 4 servings per day and added sugars and highly processed oils should be avoided entirely.

Eat More Protein

Rollins says the previous dietary guidelines demonized protein in favor of carbohydrates.

“These guidelines reflect gold standard science by prioritizing high-quality, nutrient-dense protein foods in every meal,” Rollins says. “This includes a variety of animal sources, including eggs, poultry, seafood, and red meat, in addition to plant-sourced protein foods such as beans, peas, lentils, legumes, nuts, seeds and soy.”

To put the new protein recommendations into perspective, Sigrid Johannes, executive director of government affairs for the National Cattlemen’s Beef Association, says for folks who should be consuming 1.6 grams of protein per kilogram of body weight that’s a 100% increase in recommended daily protein intake.

Dairy’s Seat at the Table

Dairy emerged in a strong position under the new dietary guidelines, with federal nutrition guidance supporting dairy at all fat levels for the first time.

“One of the key messages they’re telling consumers is eat dairy and eat dairy at all fat levels — that’s whole milk, cheese and butter,” says Matt Herrick of the International Dairy Foods Association. He calls it “a significant watershed moment,” reflecting how many families currently eat and shop today.

Echoing Herrick’s perspective, National Milk Producers Federation President and CEO Gregg Doud adds by better recognizing both fat and protein, the guidelines give a fuller picture of dairy’s nutritional value.

“Not all fats are created equal, and because the guidelines acknowledge this, dairy’s benefits are better reflected in this iteration of the guidelines,” Doud says.

When it comes to protein, consumer demand is reshaping the category, with cottage cheese at its highest level since the 1980s because of the high-protein trend, Herrick notes.

“Consumers are looking at labels more than ever and trying to find cleaner, less processed foods. Dairy fits that bill. Most products have just a handful of ingredients, and they’re all high in protein. People are turning to protein for growth, energy and overall health, and we’re going to continue to see consumers look to dairy to fulfill their protein and healthy fats needs,” Herrick says.

The processing sector has grown alongside the rising demand for dairy, reflecting both increased production and changing consumer preferences. Roughly $8 billion has been invested in new processing facilities from 2022 to 2025, with another $11 billion expected through 2028.

“We’re going to continue to see investments in processing facilities — new plants, updated lines and more capacity — to meet growing consumer demand for dairy protein and healthy fats,” Herrick notes.

Eat More Meat and Poultry

When it comes to meat and poultry, Julie Anna Potts, Meat Institute President and CEO, says Secretary Rollins and Secretary Kennedy’s leadership have simplified the dietary guidelines making it clear meat is a protein powerhouse.

“Robust scientific evidence demonstrates that meat is a rich source of high-quality protein, essential vitamins and highly bioavailable minerals that support human health throughout the lifespan,” Potts says.

Kansas beef producer Marisa Kleysteuber describes the new “commonsense” dietary guidelines as “exciting and refreshing.”

“As beef producers we are blessed to work with a ruminant animal that can utilize Mother Nature’s production of cellulose from rain and sunshine and then convert it to one of the most nutrient rich proteins there is,” she says. “Whether the consumer is desiring an organic, grass fed or corn fed beef product, there are cattlemen and women all over the U.S. who put their heart into raising these cattle to produce a nutritious and delicious product that we have always believed in and now our leaders are standing behind the ranchers and farmers of America.”

Quintessentially American foods such as burgers, steaks, pork chops and Easter hams can remain a staple of American households, and the guidelines go so far as to recommend parents introduce nutrient-dense foods, including meat, early and continue focusing on “nutrient-dense foods such as protein foods” throughout childhood.

“America’s pork producers appreciate the 2025 dietary guidelines putting pork front and center on the plate. They took note of producer concerns and rightly gave pork and other high-protein, nutrient-dense and delicious meats their due when it comes to Americans’ health and dietary habits,” says Rob Brenneman , National Pork Producers Council president-elect and pork producer from Washington, Iowa.

Maddie Hokanson , a Minnesota pork producer and mother of two, says the new dietary guidelines’ strong emphasis on protein is a positive for the pork industry. She believes the new guidelines, paired with pork’s quality nutrition and versatility, bring together the perfect opportunity to increase pork consumption and demand in the U.S.

“As pig farmers, we are proud to produce a meat product that is packed with high-quality protein, while also being nutrient-dense with many essential vitamins and minerals,” Hokanson says. “As a parent to young children, I see both the physical and cognitive benefits of prioritizing protein in the diet at all ages, and I’m excited to see what the short- and long-term effects of this recommendation will be.”

Three Servings of Veggies and Two Servings of Fruit

Dairy and meat weren’t the only items at the top of the new dietary pyramid. Fresh fruits and vegetables were also given top billing.

“Diets rich in vegetables and fruits reduce disease risk more effectively than many drugs,” says Robert F Kennedy Jr., Secretary of Health.

The new dietary guidelines recommend three servings of vegetables and two servings of fruit per day. Like past editions of the dietary guidelines , the new guidelines recommend Americans eat “a variety of colorful, nutrient-dense vegetables and fruits” and advises whole produce items be eaten “in their original form.” Though not explicitly stated, the updated guidelines also call out “frozen, dried, or canned vegetables or fruits with no or very limited added sugars” as good options.

“Today’s dietary guidelines reinforce the critical role fruits and vegetables play in overall health,” says Mollie Van Lieu, International Fresh Produce Association vice president of nutrition and health, in the group’s response. “Scientific evidence consistently shows that fruits and vegetables should make up the majority of what people eat. The Administration’s focus on whole foods is an opportunity to increase fruit and vegetable intake, as they are the most nutrient-dense foods available.”

Rollins Teases Plan to Expand Real Food Retail Accessibility

There was more than the new dietary guidelines announced at the press event. Rollins mentioned upcoming changes at retail she says would increase the accessibility of whole, healthy foods to those in food deserts.

“Soon, USDA will finalize our stocking standards,” she says, explaining retailers that take SNAP benefits are bound by the stocking standards. “Very soon we will be finalizing that rule that will mandate all 250,000 retailers in America to double the type of staple foods they provide for America’s SNAP households. This means healthier options will be in reach for all American families, regardless of circumstance, at levels never seen before in our country.”

Grains and Oilseed Industry Focuses on Positives

In terms of grains, in its guidance USDA recommends Americans “focus on whole grains, while sharply reducing refined carbohydrates.” The National Association of Wheat Growers (NAWG) shared mixed reactions to the changes.

“We appreciate the continued recognition of whole grains as an essential part of Americans’ diets,” said a spokesperson with NAWG in a statement to Farm Journal. “However, we are concerned that some portions of the new guidelines around grains and wheat are unintentionally confusing. Wheat, wheat flour, and foods made from wheat have been nutrient-rich, life-sustaining staples for tens of thousands of years and deserve clear, continued support as a central part of our nation’s diet.”

The American Soybean Association (ASA) focuses on the positives saying it highlights the importance of increased protein consumption, including plant-based proteins, such as soy-based foods. They also emphasize prioritizing healthy fats, including oils rich in essential fatty acids like soybean oil.

ASA says an addendum continues to call into question the process of soybean oil extraction, which it says is scientifically proven to be safe for human health.

“Soybean oil and soy protein play a critical role in the health and nutrition of Americans,” says Scott Metzger, ASA president and Ohio farmer, in a press release. “We remain deeply concerned by the rhetoric and selectively cited studies regarding the health and safety of soybean oil in DGA supporting material.”

Metzger says soybean growers will continue to work with the administration and educate MAHA commission leadership on the health benefits of soy-based foods and soybean oil.

The National Oilseed Processors Association (NOPA) echoed those concern: “Vegetable oils, or “seed oils” as they’re sometimes referred to, are a significant provider of essential fatty acids and remain a safe and cost-effective source of dietary fats in the American diet, as they are globally,” said a NOPA press release. “However, some appendices rely on a narrow evidence base with limited citations, which is concerning given the administration’s rhetoric questioning the safety of certain vegetable oils despite an established scientific consensus.”

NOPA also argues oilseeds support the production of affordable meat, dairy and eggs as meal produced from oilseeds are a key component of livestock diets.

Thanksgiving Turkey Dinner Costs Dip By 5%

Wed, 19 Nov 2025 17:11:12 GMT

As families across America prepare for their Thanksgiving celebrations next week, the 40th annual American Farm Bureau Federation (AFBF) survey brings some welcome news for the wallet.

The classic Thanksgiving dinner for 10 people is projected to cost an average of $55.18, marking a 5% decrease from last year. However, this price point remains notably higher than five years ago.

A Long-Standing Tradition
Since 1986, the AFBF has tracked and reported the cost of a traditional Thanksgiving meal. Each year, volunteer shoppers from across the U.S. and Puerto Rico canvas local grocery stores—or their online counterparts—to record prices for a standard list of holiday staples.

The list of items surveyed for prices includes turkey, cubed stuffing, sweet potatoes, dinner rolls, frozen peas, fresh cranberries, celery, carrots, pumpkin pie mix and pie crusts, whipping cream, and whole milk.

This year’s grocery bill highlights several price shifts. Four key items saw a drop in price: the centerpiece turkey, cubed stuffing, fresh cranberries, and dinner rolls.

Conversely, five items—sweet potatoes, frozen green peas, vegetable tray, whole milk, and whipping cream—experienced price increases. Pumpkin pie mix and pie shells remained virtually unchanged from last year’s figures.

Regional Differences Contribute To Costs
For those celebrating in the West, the classic Thanksgiving dinner for 10 people costs $61.75, making it the most expensive region and approximately 12% higher than the national average. Families in the Northeast also face prices above the national average, with their classic meal coming in at $60.82. The South boasts the most affordable holiday meal at $50.01, closely followed by the Midwest at $54.38.

Americans living in the West will pay, on average, nearly $10 more per meal than those living in the South.

(AFBF)

If you expand dinner options to include ham, Russet potatoes, and green beans, including these additional items elevates the total meal cost for 10 to $77.09, or $7.71 per person.

Regionally, the South again offers the lowest total at $71.20, followed by the Midwest at $76.33. Both the Northeast and the West saw a jump in cost, reaching $82.97 and $84.97, respectively. The West once more stands out, with costs higher there than in other regions.

Turkey Takes a Back Seat in the Bill
Historically, the turkey has been the undisputed heavyweight on the Thanksgiving receipt, often accounting for an average of 43% of the total dinner cost. However, in 2025, a 16-pound turkey represents only 39% of the cost for a 10-person dinner—its lowest share since 2000.

Turkey prices have dropped for consumers this year because, in many instances, retailers are using them as a loss leader to attract shoppers.

(AFBF)

A 16-pound turkey will set shoppers back an average of $21.50, reports the AFBF, a significant 16% decrease from 2024. While fresh turkey prices continue to climb as the poultry sector battles highly pathogenic avian influenza (HPAI), the prices for frozen turkeys—the preferred choice for most Thanksgiving feasts—are steadily declining.

Adding to this trend, turkey demand outside of the holiday season continues to wane, with the average American consuming only 13 pounds of turkey per year, nearly 3 pounds less than six years ago.

Side Dishes Gain Weight on the Grocery Receipt
Despite the overall dip in Thanksgiving meal costs this year, side dishes now command a larger share of the total grocery bill. Price increases for fresh produce and essential baking ingredients underscore elevated costs throughout the entire supply chain.

Items like fresh vegetables and sweet potatoes registered some of the most substantial cost increases. A veggie tray is up by more than 61%, and sweet potatoes saw a 37% jump.

Several items saw price reductions this year, helping to mitigate the overall meal cost, according to the AFBF survey. Dinner rolls are down 14.6%, stuffing is down 9%, and cranberries are down 2.8%.

Vitamin E: What's the Requirement?

Mon, 23 Nov 2020 00:38:35 GMT

Inconclusive research leads to expensive guessing.

Vitamin E can be one of the most expensive supplements in our rations, and in my opinion, we don’t know the cow’s requirement.

Vitamin E is an antioxidant and is supplemented to reduce oxidative stress in tissues caused when reactive oxygen species (ROS) accumulate. These ROS have been shown to be associated with an increased incidence of retained placenta and metabolic diseases. The National Research Council (NRC) recommends supplementing 1000 IU of vitamin E prepartum and 500 IU postpartum. Researchers at Ohio State have suggested that levels as high as 4,000 IU prepartum may be beneficial.

So, what does this cost the dairy producer? Vitamin E production is controlled by very few players in the world – primarily the Chinese. The market goes up and down as these producers manipulate the market. The approximate cost for 1000 IU of vitamin E, by the time it gets to the farm has varied over the past 6 years from as low as 3¢/cow/day to over 10¢/cow/day. So, 4000 IU could cost as much as 40¢/cow.

There have been no definitive titration studies done with vitamin E under different physiological or environmental conditions to really pinpoint a requirement. We went from 300 IU to 500 to 1000 and then jumped to 4,000 IU as recommended supplemental levels. What if you’re feeding fresh forage, which can be loaded with vitamin E, or only ensiled forages with very little vitamin E?

I recently read a University of Florida study, where the effect of heat stress and vitamin E levels were examined. The hypothesis was that heat stress increased oxidative stress in the animals and vitamin E may help alleviate this. Cows were supplemented with levels from 500 to 3000 IU vitamin E pre and postpartum under cooled or heat stressed conditions.

The results were pretty much inconclusive, although feeding more vitamin E did increase the level of E in the blood. Feeding the high level of vitamin E to mature cows under heat stress increased milk, but first-calf heifers actually produced less milk with higher vitamin E supplementation, whether heat stressed or not. Based on blood NEFA levels, the first-calf heifers were under less metabolic stress than cows. The researchers theorized that supplementing too much vitamin E to the less stressed heifers may have caused greater radical formation which reduced performance. Wow, too much vitamin E?

There’s no question that vitamin E is a required nutrient. Dairy producers spend a lot of money on vitamin E, based on what I consider less than adequate research.
We’ve really dialed in on protein and carbohydrate requirements in recent years. I think we should do the same with vitamin E. Since the U.S. doesn’t produce any, maybe we could make it a national security issue.
