Launching a New Chapter in Alfalfa Water Research

Yme Bosma 55-acre alfalfa field near Rising Star, Texas

In the heart of Central Texas, just outside May, we’ve begun an exciting research collaboration with Yme Bosma Dairy—a family-run dairy that relies on homegrown forage to feed their high-producing herd. This project centers on a 55-acre alfalfa field managed under a center pivot irrigation system, and our goal is straightforward but critical: improve the way we grow and water alfalfa in drought-prone environments like ours.

Why Focus on Alfalfa and Water?

Alfalfa is a high-value, nutrient-rich forage crop widely used in dairy systems, especially organic dairies. But it’s also water-intensive, and in regions like Central Texas or even Texas in general, where every drop counts, managing water wisely isn’t optional—it’s essential.

We’re not just asking “How much water is used?”—we’re digging deeper:

  • Can we grow more forage with less water?
  • Can we use in-field sensors and aerial data to guide irrigation decisions?
  • Can we improve the crop coefficient (Kc) used in scheduling tools, making them more accurate for this region?

Field Setup: A Unique Design for Real-World Impact

Pierce Center Pivot with app-based control

The project field is irrigated by a Pierce center pivot, managed by Dyson Irrigation using app-based controls. What makes this setup unique is how we’ve divided the field. Rather than square or rectangular plots, we’ve created 10-degree radial swaths that fan out from the center of the pivot pad—like slices of a pie. Each wedge can be irrigated differently by adjusting the pivot’s speed, allowing us to simulate a range of water conditions all within one field.

These swaths have been geolocated precisely, so we know exactly where each biosample or soil moisture sensor reading comes from. Though the field layout map is a great visual aid, our true experimental plots are mapped in GIS with accurate GPS coordinates for each treatment zone.

This project includes a lot of folks but is coordinated by the Digital Agriculture Group out of the Texas A&M AgriLife Research and Extension Center in Corpus Christi – Digital Agriculture. The group is led by Dr. Mahendra Bhandari and his team of researchers and students, all very hard workers!

Tools and Technology: Ground to Sky

What makes this project especially powerful is the technology behind it. We’ve installed three-foot-long soil moisture sensors (Goanna Ag) in each plot to monitor how deeply water penetrates and how long it stays available to the plant. These in-situ sensors give us real-time feedback at the root zone—a critical layer for alfalfa, especially in hot summer months.

In addition to ground sensors, we’re collecting UAS (drone) imagery every 15–20 days, paired with high-resolution satellite imagery. These tools will help us develop:

A GPS receiver to geolocate the different areas for monitoring.

  • Evapotranspiration maps showing water use across the field
  • Biomass prediction models based on imagery
  • Real-time irrigation scheduling tools using soil moisture and crop stage

All of this data funnels into decision-support models like SEBAL (Surface Energy Balance Algorithm for Land) and artificial neural networks, which help us simulate and optimize irrigation in silage alfalfa production.

What We Hope to Deliver

This is just the beginning. Over the next growing seasons, we aim to provide:

  • A better understanding of alfalfa water use and crop coefficients in Central Texas
  • New irrigation scheduling recommendations tailored for silage production
  • Biomass yield maps and stress indicators derived from aerial data
  • Practical insights for dairies and forage growers seeking to optimize yield while conserving water

This project is part of a broader effort to make alfalfa a more drought-resilient crop, and we’re excited to share what we learn with farmers, agronomists, and researchers across Texas and beyond.

This research is supported by the National Institute of Food and Agriculture, U.S. Department of Agriculture award number 2023-70005-41080 (Drought Resilient Alfalfa Production (D-RAP) Using Digital Agriculture and Machine Learning) with a joint collaboration between Kansas State University and Texas A&M AgriLife Research and Extension.

Stay tuned—we’ll be posting updates after each harvest, including images, early data trends, and insights from the field.

Texas Organic Agriculture Surges Forward with National Recognition

TOPP Impact Report Underscores Texas Leadership in Organic Milk, Cotton, and Peanuts

As national organic food sales soar past $71 billion, Texas is emerging as a dominant force in organic agriculture, bolstered by strategic investment from the USDA’s Transition to Organic Partnership Program (TOPP). According to TOPP’s newly released 2024 Impact Report, over 3,800 new operations have been certified nationwide, and Texas producers are taking the lead in organic innovation, acreage growth, and market share.

Texas is now home to more than 448 certified organic farms and over 611 organic handlers, producing across 580,000 acres in at least 88 counties. The Lone Star State ranks No. 1 nationally in organic milk, cotton, and peanut production — a testament to the state’s diversified and growing organic economy.

In 2019, Texas organic agriculture generated $424 million in sales and nearly $939 million in total economic output. By 2025, projections indicate the sector will contribute more than $1.4 billion in statewide economic output and support nearly 12,500 jobs, with a compound annual growth rate of 7% that mirrors national trends.

“Texas isn’t just keeping up—we’re leading,” said Bob Whitney, Organic Program Specialist with Texas A&M AgriLife Extension. “From dairy and peanuts in the west to vegetables and rice in the south and east, organic producers across Texas are creating real jobs, feeding local communities, and demonstrating what’s possible when farmers get the support they need.”

TOPP, launched in 2022 as part of the USDA Organic Transition Initiative, has helped hundreds of producers nationwide navigate the complex path to organic certification through mentorship, technical assistance, and community networks. Texas producers have benefited through local TOPP training events, bilingual outreach, and one-on-one mentoring that is helping new farmers transition more successfully and more sustainably.

As part of the six-region national framework, TOPP’s Southwest region includes a coalition of regional organizations and universities—including Texas A&M AgriLife Extension—that provide tailored support to Texas producers. Nationally, more than 260,000 acres have been added to certified organic production through the program’s efforts.

Texas’s success stands out even as some regions of the U.S. experience flat or declining organic acreage. Experts credit the state’s focused approach—blending grassroots mentoring, university-led research, and Extension outreach—for enabling sustainable growth.

TOPP’s report also highlights growing consumer demand: 88% of Americans recognize the USDA Organic label, and nearly 60% believe it justifies higher prices, creating strong economic incentives for Texas farmers to meet that demand domestically.

“TOPP is about more than transitioning farms—it’s about building community, restoring soil, and securing food systems,” said Whitney. “And here in Texas, it’s working.”

Organic Beef Demand is on the rise!

Organic Beef is Booming: Why Texas Ranchers Should Take Notice

Organic beef is no longer a niche product—it’s a fast-growing category with powerful momentum. According to the Organic Trade Association’s 2024–2025 Organic Market Report, organic beef sales surged 36.7% last year. That’s the highest growth rate of any food category—and the most significant gain in the organic beef market in 20 years.

This demand is fueled by consumers looking for:

  • Clean, hormone- and antibiotic-free protein
  • Animal welfare
  • Environmental stewardship

However, much of this market is currently being supplied by imports—primarily from Australia and Uruguay. That’s where Texas ranchers come in.

Texas Has the Cattle—Now It Has more Processors

Texas leads the nation in cattle production, yet very few certified organic beef operations have emerged in the state. The reason? Lack of access to certified organic meat processing facilities.

That’s now changing.

Two Texas processors are leading the way:

  • All Hale Meats near Wolfforth, close to Lubbock
  • Huse’s Country Meats in Malone, TX (east of Hillsboro)

Huse’s, a long-standing family-owned processor known for quality smoked meats, has recently become certified organic, thanks in part to rancher Larry Widman of Leafy Creek Farm. Larry helped initiate and complete the certification process so he could market his own beef—and he continues to assist other ranchers with organic slaughter scheduling.

Modeling Success: Open Range Beef in Nebraska

Texas ranchers can look to Open Range Beef in Nebraska as a blueprint. Run by Tim Goodnight, this company processes and markets organic beef across multiple channels—from retail and foodservice to private label and club stores. Their success proves that domestic supply chains can work—when producers and processors are aligned.

Contact Tim Goodnight 🌐 openrangebeef.com

Why Texas Is Ideal for Organic Beef

Texas has a unique opportunity:

  • Abundant native rangeland well-suited to low-input, organic grazing
  • Proximity to two certified organic processors
  • A central location to serve local, regional, and statewide markets

With the infrastructure in place, ranchers can now tap into the fastest-growing sector in organic food.

One potential outlet is Pederson’s Natural Farms in Hamilton, TX, known for high-quality natural meats. As supply increases, retailers like Pederson’s—and others—can become key distribution points for Texas-grown organic beef.

Could Tariffs and Trade Changes Open the Door Further?

While Australia and Uruguay currently supply a large share of organic beef imports, this supply chain is vulnerable to:

  • Global trade shifts
  • Export restrictions
  • Increased transportation costs
  • Potential U.S. tariffs on imported meat

As U.S. policymakers and trade organizations review food security and prioritize resilient domestic supply chains, we may see fewer imports and greater opportunities for U.S.-based production. That’s good news for ranchers with the capacity to go organic—and for consumers looking for American-grown, organic, and ethically raised meat.

Next Steps for Ranchers

If you’re in Texas and run a cow-calf, grass-fed, or finished beef operation, now is the time to:

  1. Explore organic certification of your pastures and practices.
  2. Connect with a certified processor like Huse’s or All Hale Meats.
  3. Develop local markets—co-ops, farm stores, health food outlets, and online direct-to-consumer sales.

This isn’t just about beef—it’s about building a more local, more ethical, and more profitable Texas-based food system.

What the Haney Test Revealed: Biological Benefits of Cover Crops in Action

Over the past few weeks, I’ve written about what cover crops like Sunn Hemp, Tepary Bean, and Cowpea leave behind in the soil and how their nutrient contributions stack up in standard soil tests. But it wasn’t until we looked at the Haney Soil Test results from March 2025 that we could truly see the biological influence each of these summer cover crops had on the soil. In this post, I’m sharing new insights drawn from those results and why I believe every grower should consider this test when evaluating cover crop performance.

Why the Haney Test?

Unlike standard chemical soil tests that only measure nutrient availability, the Haney Test adds a biological lens. It measures microbial respiration (CO₂-C), available organic nitrogen (Haney N), and gives an overall Soil Health Score. These indicators help us understand how biologically active the soil is and how much of the nutrients are likely to cycle into plant-available forms.

For organic and sustainable systems, this is vital. We’re not just feeding the crop—we’re feeding the soil.

All Plots Started Equal

Just to set the stage: all test plots had a rye cover crop terminated in early spring 2024 and were kept bare and weed-free through summer. The only difference among plots came when Sunn Hemp, Tepary Bean, or Cowpea was planted in August 2024. The check plot remained bare.

The Biological Winners and Stragglers

Here’s what the Haney Test results (click here to see reports) show:

  • Sunn Hemp had the highest CO₂-C (43.21 ppm), strong Haney N (74.74 lbs/ac), and the highest Soil Health Score (9.41). It fed the microbes and left behind a soil system ready to cycle nutrients. If you’re planting a high-demand crop like corn or grain sorghum, Sunn Hemp sets the table biologically.
  • Cowpea followed closely with a CO₂-C of 32.08 ppm, Haney N of 71.50 lbs/ac, and a Soil Health Score of 7.80. Reliable, balanced, and consistent—it’s a solid choice for improving soil function while conserving moisture and nutrients.
  • Tepary Bean, despite good forage quality and tissue N content (3.02%), showed low microbial activity (CO₂-C of 13.75 ppm) and the lowest Soil Health Score (6.43). It may decompose slower or produce compounds less favored by microbes. That’s not necessarily bad—it might serve longer-term fertility, but it’s not the best option for short-term nutrient release.
  • Check Plot (bare fallow) showed high mineral N (83.73 lbs/ac) and decent CO₂-C (37.14 ppm), but that’s misleading. There was no cover crop to feed soil life or cycle nutrients—just unutilized residuals from last year. Long term, this approach does not build soil health.

What This Means for Growers

The biological boost from a cover crop can be measured and managed. Without the Haney Test, we’d only be guessing how much nitrogen or biological activity remains from cover cropping. We tell growers: don’t plant blind—use this test to make more informed fertility and management decisions.

Sunn Hemp again proved why it’s a leading summer cover crop for southern systems. Cowpea is a great second choice when water is limited or biological stimulation is still desired. Tepary Bean may have a role in longer rotations but isn’t the best for quick turnover systems.

Final Thought

We use cover crops for more than just erosion control. They’re engines of soil biology, nutrient cycling, and resilience. The Haney Test gives us a dashboard to read those engines.

If you’re not already using it, this is your sign: test for biology, not just chemistry.

Organic Sorghum Resources (update)

Sorghum’s natural characteristics and compatibility with organic farming principles indeed make it an excellent crop for organic cultivation. While some traits like drought tolerance and non-GMO status are shared with conventional sorghum, these characteristics synergize particularly well with the goals and methods of organic agriculture, offering distinct advantages.

Sorghum’s Advantages

  • Drought Tolerance: Sorghum’s inherent drought tolerance makes it an ideal crop for organic systems, which prioritize water conservation and efficient use.
  • Low Fertilizer Needs: Sorghum’s ability to thrive in less fertile soils matches well with organic farming, which relies on natural fertility management rather than synthetic fertilizers.
  • Natural Resistance to Pests and Diseases: Sorghum’s inherent resistance to many pests and diseases minimizes the need for synthetic pesticides, making it easier for organic farmers to manage their crops.
  • Versatility in Use: Sorghum can be utilized in a variety of ways (grain, syrup, fodder) which allows organic producers to cater to diverse markets (food, feed, sweeteners) under organic labels.
  • Contribution to Soil Health: Sorghum’s deep rooting system can improve soil structure and increase water infiltration, beneficial effects that are particularly valued in organic systems focused on long-term soil health.
  • Crop Rotation and Diversity: Sorghum fits well into crop rotations, a cornerstone of organic farming, helping break pest and disease cycles and improving soil health without relying on chemical inputs.
  • Consumer Preference for Non-GMO: Even though there is no GMO sorghum on the market, the strong consumer preference for non-GMO products benefits organic sorghum producers, as their products are guaranteed to meet this demand.
  • Growing Demand for Organic Grains: The increasing consumer demand for organic products extends to grains, including sorghum, for both human consumption and organic animal feed.
  • Carbon Sequestration: Sorghum’s growth habit and biomass production can contribute to carbon sequestration, aligning with the environmental sustainability goals of organic farming.

While many of sorghum’s traits benefit both conventional and organic systems, its natural resilience, low input requirements, and versatility make it particularly well-suited for organic agriculture. These characteristics help organic sorghum producers minimize reliance on external inputs, align with organic principles, and tap into a growing market demand for organic products.

Buying seed?

The number of seeds per pound in sorghum varieties can vary significantly depending on the specific variety and the size of the seeds. Generally, this range can be broad, reflecting differences in genetics, breeding objectives, and end use (grain, forage, or specialty types). Here’s a general overview:

  • Small-Seeded Varieties: Can have as many as 16,000 to 18,000 seeds per pound.
  • Large-Seeded Varieties: May have fewer seeds per pound, typically ranging from 12,000 to 15,000 seeds per pound.
  • Forage sorghums and sorghum-sudangrass hybrid types tend to have larger seeds compared to grain sorghum varieties. The seeds per pound can range from 10,000 to 14,000 for forage types, with sorghum-sudangrass hybrids often on the lower end of this scale due to their larger seed size.

Sorghum Varieties

The varieties listed below are some planted by current organic growers. We are in the process of getting a better list together and will post them here!

These varieties are listed along with their respective websites for more detailed information. Company listings are down below and your source for qualified salespeople. Check with your certifier before buying any sorghum seed especially if the variety is not sold as organically produced. Since we do not have many organic, locally adapted sorghum varieties producers typically buy conventionally produced varieties without seed treatments.

FieldWatch is Here in Texas!

FIELDWATCH® WELCOMES TEXAS AS ITS 27TH STATE MEMBER

by Curt Hadley, Field Watch

FieldWatch, Inc., a non-profit company that promotes communication and stewardship among crop producers, beekeepers and pesticide applicators, announces that Texas has joined as the 27th member state.

Texas joins FieldWatch along with 26 other states, one Canadian province and the District of Columbia. The membership will enable Texas’ beekeepers (hobbyist and commercial) and crop producers (organic and conventional) to use a secure, easy-to-use online registry to identify and map the locations of apiaries and crop fields that pesticide applicators should avoid. The free and voluntary registries, DriftWatch™ and BeeCheck™, will be available to all Texas beekeepers and crop producers. FieldCheck® is the online and mobile portal that pesticide applicators can use to improve decision-making and avoid damage from spray drift to crops and beehives.

“The goal is to get beekeepers and crop producers registered through FieldWatch, so applicators can access accurate information before spraying,” said Bob Walters, President and CEO of FieldWatch. “This model has been proven to build stewardship and communication in agriculture.”

Texas’ membership decision was especially driven by the needs of crop producers and beekeepers who wanted to register the locations of their apiaries and crops. 

Want to Get Started? It is very easy…..

Above you read the press release but now we need to get you registered and your fields mapped. I am the Texas FieldWatch Data Steward, and my job is to help you with this process and to approve your fields or beehives.

First, type in fieldwatch.com into your web browser. This will take you to a screen that looks like this.

You will want to click on the square called driftwatch (for producers). Once you click on that button you will be taken to the page below.

If you are a beekeeper and want to register your hives with beecheck then you will click below the “Map My Apiaries” and be taken to this page below.

If you are just registering your cropland then you will click below the “Map My Specialty Crops” and be taken to this page below.

No matter which direction you go, crops or bees, you will need to tell us which state – Texas. Then use your email address as a username or any other name you can remember, add in your email address and then a password and hit Sign Up. Once you hit the button then this screen will appear. I went the crop route in my example, but both are similar.

Once you register all your information and click Create Account you will get this notification.

This email below came to my Gmail account telling me to click here to complete the account creation. Also notice that my Texas A&M AgriLife email address is listed down below as the data steward for the FieldWatch program. At this point I am the person getting FieldWatch up and going in Texas and working with Curt Hadley at FieldWatch we will solve any issues you have with FieldWatch!

Once you click to complete you will be taken to this screen

Clicking on the “Go to the DriftWatch Map” takes you here. Click on Texas on the map to move to………

And finally to here. Take a minute or two to get familiar with the screen. This is pretty much what you see on Google Earth or Google Maps. Use your mouse to move around the map and you can scroll in or out for Zoom.

But this is what you are interested in clicking. “Submit New Site.”

When you click then this appears.

After you answer the questions on 3 different screens you will finally get to this screen below.

I zoomed in on the field that we have certified organic at the Stephenville Research and Extension Center on Hwy 281 in Stephenville and hit the blue button for Begin Tracing. I clicked on one corner then the next till I got back to the first corner and it completed the field. 3.88 acres! The C is for cotton.

I am done with registering my certified organic field and waiting on the Data Steward with Field Watch to approve my field. Because I am the Data Steward I logged out of my “fake account” and logged back in with my official Texas A&M AgriLife email and got this screen for the field I just mapped.

As Data Steward I approved the site and now here are the approved FieldWatch sites so far for all the world to see. This map shows that we have 2 bee sites approved and now one organic cotton site approved. Simple and easy! If you have any questions or concerns, just email me: bob.whitney@ag.tamu.edu
