When in Drought, Plan It Out: Rain Harvesting

By Stephanie Kasper, University of Texas Rio GraSoil for Waternde Valley Program Manager

As a south Texas farmer, there’s not much I love more than a refreshing rainy day. However, my rain appreciation grew deeper this year after my partner John and I installed a 1,650-gallon rain harvest system at our house.

After moving into our home just outside Edinburg city limits in February 2022, we replaced most of our turf grass with a 336-square-foot vegetable garden in the front yard and an 840-square- foot one in the back, surrounded by vibrant native wildflowers.

The transformation from a lawn to food-producing gardens brought us both joy and water savings. Drought-adapted native plants require less water than traditional grass lawns, and we use drip irrigation for the vegetables, which is more efficient than overhead sprinklers. However, we wanted to reduce our reliance on the municipal water supply for outdoor plants even further, and help save the cleanest, highest-quality water for human consumption.

This desire felt ever more pressing as we settled into another hot, dry south Texas summer. Falcon Reservoir, which supplies water to the Rio Grande Valley, reached a historic low of 9% capacity in August 2022, leading to water use restrictions. Frustrated by complex water management issues and worried about our region’s long-term water supplies, I channeled that energy into action at home. I mapped my roof’s runoff potential and natural drip points, gathered supplies from Lowes, found six food-grade, 275-gallon IBC totes on Facebook Marketplace (with free delivery!), and studied YouTube videos on gutter installations.

The first rainfall after installing the gutters and tanks had me running from tank to tank, blissfully soaked, watching the water pour in. Even after nearly a year, I’m still out there for nearly every rainfall, happily watching the tanks fill and clearing any debris blocking the water flow.

A rain harvester rule of thumb is that 1 inch of rain on 1 square foot yields 0.6 gallons of potential water capture. With a roof area of 2,000 square feet and an average of 23 inches of rain in Edinburg per year, over 27,000 gallons of water flow off my roof annually. My 1,650-gallon tank storage can be filled entirely with just 1.5 inches of rain.

I arranged the tanks based on the flow rates of each roof section and with the destinations for water use in mind – two tanks in the front yard for the smaller front garden and four in the back for the larger backyard garden. The two front yard tanks are located at natural drip points, where 438 square feet of roof runoff can be channeled into them without additional gutter installations. These natural drip points are the easiest entry point for rain harvesting.

Once the rainwater is collected, the key is to use it efficiently. We use a 12V plug-in water pump to send water directly into the existing garden drip irrigation systems, eliminating the need for manual water hauling. The front yard drip irrigation uses 1.3 gallons per minute, so the 550 gallons of stored rainwater can provide about seven hours of irrigation time. The backyard system, with a water use rate of 2 gallons per minute and 1,100 gallons of water storage, provides nine hours of irrigation time.

In the past year, the stored water has helped reduce our municipal water use even further. The front yard garden required supplemental city water for only 50 out of 365 days (14%), and the back yard needed it for 153 out of 365 days (42%), with the gardens collectively producing 148 pounds of food in that time. Our city water usage came mostly during a 97-day dry stretch between late December and late March, when we received a total of only 0.5 inches of scattered rainfall. Since the backyard system was not complete until midway through last year, I expect our city water needs to decrease even further next year. The system is modular, and we can add additional tanks to increase water storage capacity based on our needs, providing flexibility for the future.

Installing a rain harvest system takes planning, funds, and maintenance, and I’m not going to suggest that it’s an easy sustainability swap that’s right for everyone. I’ve only saved a few dollars each month on my water bill at most. However, it has given me confidence in the resilience of our food-producing gardens amid heat waves and droughts and made me a more conscious water user.

Rainwater harvesting is already supported in Texas through exemptions from state sales tax on equipment and supplies. Some cities, like San Antonio and Austin, also offer educational programming and rainwater storage rebate programs to encourage rain harvesting. However, more efforts are required to promote rainwater harvesting on a larger scale, especially as Texas stares down the impacts of climate change and prepares for significant potential water shortfalls by 2040. Confronting these challenges in the Rio Grande Valley and beyond must include a reconsideration of our relationship with water, in small ways and large, to secure a sustainable future for all.

Managing Phosphorus for Clean Water

By Nina Prater, NCAT Agriculture Specialist

Almost every day, I am lucky enough to be able to take a quick walk to the creek that runs at the western edge of our property. I watch it change with the seasons. It becomes a tumultuous riot in the spring, sometimes it dries out completely in a droughty summer, in the fall the river birches drop their yellow leaves that float like tiny boats down the calm current, and in the winter ice forms on the banks and on the branches that dip into the water. This stretch of creek that feels like an old friend to me is affected by everything that happens upstream – how people manage their farms, yards, forests, and even their septic systems, as well as development – and it all can impact the clarity of the water, the health of the insects, birds, fish, amphibians and even people who spend time at the water.

This was on my mind when I was researching for an ATTRA podcast I recently recorded with my NCAT colleagues, Guy Ames and Lee Rinehart. We tackled the topic of phosphorus, an element essential for life and productive farming, but one that can have devastating negative impacts on lakes and streams if it washes off the land and into the water.

Over-application of phosphorus either in the form of a synthetic fertilizer or as manure is one of the main reasons for the huge dead zone in the Gulf of Mexico and for miles of beaches being closed every summer because of toxic algae blooms in lakes, rivers, and coastlines around the country.

I personally refuse to accept that this is “the price you pay” for food security. There are so many better ways to manage the essential macronutrient of phosphorus, and to manage waste from livestock operations so it is a resource, not a waste product, while still growing the food our communities need. We can have our clean waters and eat our cake too. (Is that how that expression goes? Something like that.)

Here are some ways to make sure you are being a good steward of your land and all the waterways downstream from you:

Regular soil testing: If your phosphorus levels are already high, don’t apply more!

Manage pH: If your soil pH is above or below the ideal range of 6-7, phosphorus becomes much less plant-available. Try to adjust your soil’s pH first before adding phosphorus.

Encourage mycorrhizal fungi: Mycorrhizal fungi partners with plant roots to help the plants access more phosphorus, in exchange for photosynthates. Try to reduce tillage to avoid damaging mycorrhizal fungi and have a diversity of plant species.

Choose the right cover crops: Some cover crops are good at scavenging and holding phosphorus in organic forms.

Follow the four R’s of fertilization: Right rate, right source, right placement, and right timing.

Keep your soil protected: Prevent phosphorus from leaving your fields in the form of soil erosion.

There are many other strategies for phosphorus management. Find our recent podcast here where we talked about the history of phosphorus fertilizer, the importance of getting it right, more tips and tricks for proper management, and much more. We all deserve to live and work on farms and ranches where you can take a dip in a cool creek after a long day’s work and not worry about fish kills and toxic algae. Proper soil and phosphorus management is essential in order to keep our waterways thriving. I’m sure everyone has their favorite spot like my creek – a swimming hole, a lake, a pond, a stream, a favorite beach vacation spot – some place you have special affection for, some place that can motivate you to find the best way to grow food or fiber, without causing harm. To find out more ways to do this, listen to our podcast, or reach out to me, Guy, Lee, or one of our many other ATTRA specialists. We are more than happy to hear about your favorite fishing hole and help you find ways to be a productive farmer with a good fertility management plan.

Healthy Soil Structure – The House of Life

By Justin Morris

Could you ever live in a house that collapsed on itself? Probably not. To begin living there, we would have to rebuild the house by adding more space between the walls, ceiling, and floor. By the same token, soil life cannot live in soils that have collapsed where there is no place for them to live. They need enough space provided by good soil structure to live and grow. And because healthy soil structure is so important to creating resiliency to droughts and floods, as well as providing nutrients for growing our food, healthy soil structure is the house of life! 

What is Soil Structure? 

Soil structure is the arrangement of individual soil particles and the space between them. Soil microorganisms fed by sugars released by plant roots group soil particles together into larger units called aggregates. Soil structure can vary from granular where there is a lot of space between aggregates (think cottage cheese or a fluffy chocolate cake; see Photo 1) to being very tight and compact where there is very little to no space between soil particles and no aggregates are visible (see Photo 2).   

Why is soil structure so important? 

Photo 1: Healthy soil has a granular or crumbly structure. Photo: USDA-NRCS

Agriculture is the conversion of solar energy into harvestable, life-giving energy. Solar energy is captured by plants, which release that energy in the form of biochemical compounds to soil life. Soil life produces glue-like compounds that enable sand, silt, and clay particles to rearrange while also bringing nutrients to plant roots. As soil particles rearrange during the aggregation process, cavities called pores are created. Pores allow soil to infiltrate and hold water that’s essential for plants and soil life. Pores also allow air to get into the soil so soil life and roots can breathe while allowing carbon dioxide to be released from the soil. Carbon dioxide rising out of the soil is captured by plants so photosynthesis can continue. Life on earth is dependent on a healthy soil with a granular or crumbly structure that promotes the capture and release of water and

promotes the exchange of gases. In short, a granular soil structure allows soil life and plants to drink and breathe.  

Think of soil structure like a house. The wood, concrete, and steel that make up the foundation, floor, walls, and ceiling are like sand, silt, and clay particles. The nails, screws, and staples are like the glue-like compounds secreted by plant roots and soil life. With nails, screws, and staples in place, the house has lots of room to live inside. But if a large earthmover moves through the house, the house collapses and the livable room inside the house is eliminated. Similarly, when tillage or another disturbance happens too frequently, the soil structure collapses on itself. Collapsed soil structure diminishes the habitat soil life needed to obtain nutrients for plants and to facilitate water infiltration and air movement.  

What are the key practices that can improve soil structure? 

Practices that can facilitate improved soil structure include the following: 

  1. Reduced tillage, strip tillage, or no-till 
  2. Three or more crops in rotation from three different plant families 
  3. Cover crop mixtures with at least eight plant species and three plant families
  4. Grazing perennial pastures that focuses on: 1) adequate leaf area post-grazing; and 2) full plant recovery pre-grazing 
  5. Grazing cover crop mixtures on cropland where possible 
  6. Mulching 
  7. Controlled traffic farming 
  8. Converting annual cropland to perennial mixtures

Healthy soil structure is the house of life. As we focus on improving the life in our soils, that same soil life can begin creating healthy soil structure with plenty of space within and between soil aggregates. This can give us healthy food plus resilience to droughts and floods. That sounds like a win-win-win!

Partner Spotlight: Dixon Water Foundation

By Mike Morris and Darron Gaus

With roots in regenerative land stewardship since 1994, The Dixon Water Foundation has been approaching one of Texas’s limited resources in a unique way. While many other groups promote better livestock management and land stewardship, Dixon is one of the few organizations nationally in its specific focus on using grazing to protect and improve water resources.  

Dixon’s mission of promoting healthy watersheds through sustainable land management is accomplished through integrating livestock, research, and education. The foundation manages four large ranches in west and north Texas totaling more than 15,000 acres “On Dixon Ranches, livestock are the tool we use to create healthier land and healthier watersheds,” says their website. 

When asked why Dixon takes such a specific approach to water conservation, Robert Potts, President and CEO, said, “Because it is what we know, and it is what we are good at.” Dixon is a leading organization in regenerative land stewardship, and they’ve been doing it for nearly 30 years, long before “regenerative” became a buzz word.

Dixon was one of the Soil for Water Project’s first funders. Their mission is similar to ours, and we owe them a great deal of gratitude. We’re fortunate to have Philip Boyd, Vice President of Science & Research, and Casey Wade, Vice President of Ranching Operations, working alongside us as we provide education and set up small-scale “safe-to-fail” trials across Texas. Dixon works with researchers at universities and nonprofit organizations like Sul Ross State University’s Borderland Research Institute and Rocky Mountain Bird Observatory to monitor their ranch management methods. These monitoring efforts include watersheds, soils, plants, and wildlife. In one study with Richard Teague, they were able to confirm that multi-paddock adaptive grazing improves water conservation and protects water quality. Philip also runs numerous education events at the west Texas ranches, along with Education Program Coordinator Melissa Bookhout at the north Texas ranches, providing practical firsthand knowledge to landowners, school children, and the public.  

Rachel Vasquez recently talked to us about her work as Vice President of Grants. She was enthusiastic about spreading the work of land stewardship and water conservation through the Dixon grants program and a new and upcoming apprenticeship program. The apprenticeship program will help new ranch managers coming out of college gain real expertise in regenerative practices that heal our land. Dixon is about conserving water resources for generations to come, so it’s appropriate that they are training young people.

Using Web Soil Survey to Learn Your Land’s Potential

By Justin Morris, NCAT Regenerative Grazing Specialist 

Have you ever wondered where the best place is to get information on the soils for your land? What if that information could tell you what kind of soil you have, how deep it is, how much water it could hold, or how much forage could be grown on each acre of your land in a year. Fortunately, there is such a source. It’s called the Web Soil Survey and you can access it from any laptop or desktop. 

Launched in 2006 by the Natural Resources Conservation Service, the Web Soil Survey allows anyone to define any area they’re interested in within the United States and retrieve all sorts of soil-related information about that area. Here’s just a small sampling of what can be found: 

  • Soil map unit symbol and name 
  • Acres of a specific soil map unit within a defined area 
  • Soil textures in the top five feet 
  • Available water supply in inches for the top five feet 
  • Land capability classification 
  • Average annual precipitation 
  • Frost-free period 
  • Rangeland production during favorable, normal, and unfavorable years 
  • Yields of irrigated and non-irrigated crops including pasture and hayland 
  • And much, much more! 

For those of you who are familiar with the hard copies of the soil survey, those are no longer available. Once you get used to using the Web Soil Survey interface, getting just the information you need without combing through a thick hard copy page by page becomes far easier to use and more accurate. And for those who still want a hard copy of something, not to worry. Everything in Web Soil Survey can be printed.  

You can get started with Web Soil Survey. Once there, click on the big green “Start WSS” button. You’ll see a map of the lower 48 states with several tool buttons just above and to the left of the map. If you happen to be interested in an area in Alaska, Hawaii, or Puerto Rico, just click on the white hand tool to pan to those areas.  

Alternatively, you can jump to any area by moving your cursor over to the menu bar at the far left and clicking on Address or State and County.  

Once you’ve found the area you’re interested in, you can zoom in by using the cursor to select the magnifying lens with the plus symbol inside it. After clicking on the magnifying lens, move the cursor over the map and you’ll notice that the cursor turned into a plus symbol instead of an arrow. Click and drag over the area you want to see in greater detail. If you need to adjust the map east, west, north, or south to get everything in full view, click on the hand button to move the map image.  

Now that you have the area you’re interested in and it’s filling up the entire interactive map view, click on one of two AOI toolbar buttons above the map. The AOI (Area of Interest) button on the left makes a rectangle, whereas the AOI button on the right makes a polygon of nearly any shape. Because field boundaries are rarely ever straight, I almost always select the polygon button. Click around the area you’re interested in and then double-click your mouse to finish the polygon.

If you’ve successfully defined an area of interest, the polygon you traced will have blue diagonal lines through it, as you see above, along with an acreage count for that area. If you weren’t successful on your first attempt to create a polygon, just try again and be sure that on your last corner you double-click your mouse to complete the polygon. If you want to adjust the polygon you just created, then click on Clear AOI on the upper left. Unfortunately, you can’t edit a single point once the polygon has been fully created. This is why you have to clear the area of interest if you want to make any modifications. You can then start over until you get it to look the way you want it to. 

Now, let’s find out what soils are on this field. Scrolling up to the very top of the webpage, click on the Soil Map tab (see below). The blue diagonal lines on the map will disappear and be replaced by lines delineating soil boundaries. For this 125-acre field, there are just two soil map units – map unit 22, which is a Labenzo silt loam, and map unit 64, which is a Withers silty clay loam. Web Soil Survey shows the number of acres for each soil map unit and their percentage of the total. By the way, this is a great feature that the hard copy soil surveys of yesteryear could never tell you.  

Clicking on the map unit name on the left of the screen reveals a new window with lots of great information about that soil (see below). Here we see the map unit description for the Labenzo silt loam, which includes information on where the soil is generally located, its composition, setting, typical profile soil texture, and properties. 

After clicking on the X in the upper right corner to eliminate the map unit description window, go to the top of the screen and click on the Soil Data Explorer tab (see below).  

 

If you wanted to know what the potential alfalfa hay production is on this field, click on Vegetative Productivity (see above) under the Suitabilities and Limitations Ratings menu. This reveals a lot of different crops, some of which are not suitable for growing in this environment. Scroll down the list of different crops and click on Yields of Irrigated Crops (Component). Click on the dropdown menu and select Alfalfa Hay. Finally, click on View Rating. 

 

Now we have a rating for alfalfa hay in tons per acre for the whole field by soil map unit. The numbers listed under the Rating column are only an estimate and should be used as a rough guide, not as numbers that are absolutely accurate.  

If you want to save this information for the future or print it, click on Printable Version at the top right of the page (see below).  

This is just one of nearly countless ways to find soil and crop productivity information for a specific piece of land. I’ve covered maybe one percent of what Web Soil Survey has to offer. If you have additional questions on how to use this tremendous tool, just contact your local USDA-NRCS office.    

 

High Hope Farm: Regenerative Agriculture in Action 

By Luz Ballesteros and Felicia Bell

Soil for Water network member High Hope Farm is located in the “black prairie” country of western Clay County, Mississippi, and is owned and operated by Johnny and Deb Wray. Soil for Water Mississippi team leader Felicia Bell recently sat down with Mr. Wray to record an interview, discussing his regenerative journey and the improvements he’s seen in his farm’s soils. 

 In 2008, the Wrays decided to commit full-time to farming and moved permanently to the farm, after being inspired by Wendell Berry’s sustainable agriculture and local food systems philosophy. On their 38-acre farm, they raise regenerative grass-fed beef and lamb with two goals — providing safe, healthy beef and lamb to local consumers and sharing their regenerative agriculture journey with younger generations, hoping someone will follow in their footsteps. They use no steroids, growth hormones, antibiotics, or other chemical products. Their “high hope” is “to have a place that offers hospitality to friends and strangers alike — a welcoming table of good, healthy natural food, and a spot where earth, animals, plants, and people live, work, and play together harmoniously.” 

When the Wrays first began, they tested their soil and found it was deficient in nitrogen, phosphorus, and potassium (NPK) minerals. Going against conventional wisdom, they decided not to depend on chemical inputs to correct these problems but instead chose to follow intensive rotational adaptive grazing to improve their mineral cycle. These decisions have paid off with dramatic improvements in their soil health. After 14 years of regenerative-adaptive management, Johnny was happy to share that current soil tests show significant improvements in organic matter at almost 6% and no NPK deficiencies.  

Additionally, research on the farm by Mississippi State University showed that roots were deeper, soil microbiology was increasing, and some native grasses were returning, so much so that Johnny developed a new problem — growing too much grass. However, after consulting with Dr. Allen Williams, Johnny decided to let the paddocks he couldn’t manage rest because in the end tall grasses have deep roots that play a significant role in water infiltration and soil health. 

This increased soil health has made High Hope Farm more resilient to unpredictable weather changes. Johnny mentioned that he realized he is a “dirt farmer” because “as you improve your soil, you improve your grasses, and you improve your livestock.” He has noticed a decrease in water runoff and soil erosion. Keeping the ground covered year-round also keeps the soil’s temperature noticeably cooler during hot Mississippi summers. These are all indications of a healthy soil sponge that captures, holds, and uses water more efficiently. Johnny says that observing these improvements as a direct result of his management is “very encouraging,” and has made his operation profitable. 

Johnny mentioned great resources that helped him in his journey, including Understanding Ag, ATTRA, Soil Health Academy, USDA-NRCS, Mississippi State University, and regenerative movement pioneers like Dr. Allen Williams. He also emphasized the importance of being part of local producer networks to learn from others. These experiences have shown him firsthand how diversity and ecosystem dynamics are a fundamental part of regenerative farming.

Paddock Design, Fencing, Water Systems, and Livestock Movement Strategies for Multi-Paddock Grazing

A Conversation with Guille Yearwood

By Lee Rinehart, Sustainable Agriculture Specialist 

“If you always leave grass behind, you never run out of grass.”

I was going to save this quote for the end of this article; when I heard it during our conversation, I knew it would nicely summarize Guille (Gil) Yearwood’s philosophy. Now, I think it’s better to start with this quote. It’s an observation he had, “one of those moments,” in his words, back in the 1980s when he began his transition from continuous grazing to a rotational system. “I’ll never forget that day years ago when I went back to a grazed paddock a week later and saw regrowth.” It was something he’d never seen before. “When you graze a pasture continuously, you have no idea how much grass you have because its continually disappearing.” After Guille switched to rotational grazing, his paddocks would look like a hayfield four weeks after grazing. This, in his words, “is totally different and totally better.”

Guille Yearwood has been ranching forever. He started during his teenage years—1975 to be exact—and has been raising cattle ever since. When he started, he had other businesses going as well as the cattle work—25 years in real estate for one—but Ellett Valley Beef Company has been his full-time job since 2008.

Ellett Valley Beef Company encompasses seven locations around Blacksburg, Virginia, mostly on leased property, on which he grazes seven groups of South Poll beef cattle—a total herd of around 350 animals. Back when he first got the rotational grazing bug, by paying attention to Virginia Tech’s rotational grazing research, Guille divided his pastures into eight or 10 paddocks and began grazing stockers through the rotation. This is when he had his “aha” moment. He saw his forage yield increase immediately, and though the gains per head were not what he was used to, he noticed a higher herd weight gain because he could easily increase his stocking rate. Guille realized this new system could be taken up a notch, and now has 80 paddocks spread across all his pastures.

Cows grazing fescue – Oct. 2021

Guille would travel up to 90 miles a day checking and moving cattle before he reduced the number of leases a few years ago from 13 locations. Now, they’re all closer to home, significantly reducing the time to check and move cattle. Now, he and a part-time hired hand can check and move cattle more efficiently. He relies on grass alone and follows adaptive management techniques with frequent moves, mostly daily, and recovery periods of seventy to ninety days to allow for full plant recovery before the next time cattle see the paddock. Guille considers his system to be truly regenerative. In fact, he started regenerative grazing long before term came about, and he’s glad it did “because it’s a good term.” It accurately describes his way of doing business. His regenerative practices include highly diverse pastures, grazing for animal impact and nutrient cycling, and long recovery periods for plant rest and accumulation of high amounts of organic matter to the soil.

Ranch Profitability  

“To be profitable, I need to graze all year, if possible,” Guille noted. His goal is to produce excellent grassfed beef and be profitable, and to accomplish that, his focus is on grazing as many cattle as he can through the winter. Some time back he began thinking about return on investment and started looking at the farm this way, realizing he needed to run this like his other businesses. He did an economic analysis and a budget and figured out that he couldn’t afford fertilizer or hay equipment. “I saw that [buying fertilizer and making hay] would not make a profit, so I got rid of them.” Instead, Guille buys hay to cover the 40-65 days during the year when he needs it. For the remainder of the year, the cattle graze fresh and stockpiled pasture. In fact, the interest he received from selling his hay equipment covered his hays costs, and he’s never looked back.

Guille’s pastures have been fertilizer-free since 2000. Prior to transitioning off of fertilizer, he had broadcast clover for several years, as he was particularly concerned about nitrogen fertility. But the second year after stopping nitrogen applications, he fertilized a fescue pasture in August, a common practice for preparing fescue for winter stockpile. However, after comparing days of grazing data between this and the prior year when no fertilizer was used, he realized he lost money with the fertilizer application. The days of grazing were the same for both years. This was the end of Guille’s use of purchased fertilizer. The diversity of his pastures, which included legumes and grasses, coupled with his adaptive management, provided the nutrient cycling and carbon sources he needed to be sustainable without it. All the while, he was ratcheting up his grazing techniques, trampling residue, and feeding hay on land that needed the nutrients. It seems that when he decided to go fertilizer-free, he had already been taking care of the soil for years, so he was ready.

Educational Philosophy

Guille’s college work includes an English degree from Virginia Tech and a master’s in English from Rice University. It is easy to tell from reading the blog entries on his website that his liberal arts education sharpened his critical thinking skills and gave him a foundation well suited for the complexities of agriculture. Since then, he has been inspired by Joel Salatin, especially his book Salad Bar Beef, which he says had a big impact on his philosophy. Other luminaries that inspired him include Andre Voisin, the “first true scientist that addressed rotational grazing,” Newman Turner, Jim Gerrish, and Allen Williams, who “has it figured out and is backed up with real science.” He learned about brix levels in forages from Williams, and though skeptical at first, he has seen a tremendous difference by moving cattle to new paddocks in the afternoon when brix levels are highest. Guille has learned so much and, with a natural drive and desire to help beginning and transitioning farmers, has much to share from his experience.

“The big challenges a new farmer needs to overcome are the tactile, physical problems. These are harder for people to pick up than we realize. For instance, a polywire reel is a foreign object to a beginner, but for me, it is an ordinary tool like a screwdriver.” Guille helps beginners by simply taking them out and involving them in moving cattle, checking cows, or moving polywire, and showing them how to shut off the power, tie polywire, or set posts. Newcomers are fascinated by the complexities of grazing tools and procedures, and he has come to understand how new this is to some people, so he trains people from this tactile perspective. Also, new farmers don’t know cattle and it’s a long learning process. His advice is to read all the books you can at night and during day go to the stockyard. Seriously, the stockyard. When a cow comes into the pen, evaluate her breed, condition, and weight, and especially listen to the people talking around you and pay attention to what they are observing.

“Some things we are just going to battle,” he said. For instance, weeds in fence lines are a major struggle for Guille. He has miles of electric fence and keeping them maintained is labor-intensive. He can spray a lot of fenceline in a short amount of time but would rather not use herbicides, and some lessors don’t want him to spray pesticides. “Weed eating would occupy me all summer, and then there’s the yellow jackets!” It’s an ongoing struggle, and he makes it clear he doesn’t have all the answers. “On this ranch you’ll see a lot of mistakes,” he said, but he has learned more in the past four years about grazing than in the 10 years preceding it. “Don’t panic… just try it” is the best advice he can give. “Don’t be afraid to set the field up and try it; if it doesn’t work, adjust and move on.”

Fine Tuning and Adaptation

Pasture with johnsongrass, fescue, clover, and stickweed (Verbesina occidentalis).

Guille doesn’t farm his land. Rather, he follows the truly regenerative practice of grazing what is available with one-day grazing periods and 70- to 90-day recovery periods. Plant communities change seasonally and yearly as different (adaptive) grazing practices are employed on the land. His pastures are diverse and include johnsongrass, which many graziers have tried to eliminate but he sees as complementary to his grazing system. Johnsongrass has usually been found in bottom land but now it’s moving on to upper lands, places he has never seen this hardy perennial grass before. It works out well in his grazing system because by the time he gets around to a paddock with johnsongrass, it’s fairly mature so it has no prussic acid problems. Also, there is enough diversity in the pastures and grazing them before the frost works well in his rotation.

Guille’s adaptive management hits a high note when it comes to finishing steers on grass. When trying to finish a group of steers (get ready, this is brilliant), he mimics continuous grazing (which, though hard on the pasture is good for optimizing individual animal gain) to allow the animals to exhibit more grazing selectivity. He keeps the rotation going at about the same grazing and recovery periods but gives the feeder steers bigger paddocks. “I’ve measured these results. On excellent pastures with medium-frame cattle, one group gained 4.2 pounds over six weeks and another group gained 4.6 pounds.” If a normal paddock size is a half-acre, he gives the finishers an acre and a half for the same period, giving them the ability to be more selective in their grazing.

Guille Yearwood currently serves as Farmer Advisor for the Virginia Soil for Water Project and is working with the Virginia Association for Biological Farming to plan a field day on his ranch in the spring of 2023, where participants can see up close the practices that he has been refining for the past 50 years. “This is the best job in the world,” Guille noted at the end of our last talk. His passion for the land and grass-based agriculture is palpable, as you’ll see if you make it to the spring field day. And, oh yes: Guille is an excellent writer, with a witty humor and deep love and knowledge of his subject, as you can see from the blogs posted on his website.

Partner Spotlight: Mary Sketch Bryant

By Lee Rinehart, Sustainable Agriculture Specialist 

No level of education can prepare a student for the deep work of community building around resource conservation issues, especially in low-income counties that have experienced environmental catastrophe. But this is how Mary Sketch Bryant cut her teeth in the demanding world of land-use policy and environmental and community restoration. With a newly minted degree in environmental studies, Mary found herself in California working with a forest restoration collaborative. She began connecting with local folks to find answers around community resilience and conservation. How could she help rebuild this community devastated after the Butte fire tore through 70,000 acres of forest, farms, and homesites?

Mary’s experience in California gave her insight into the human dimensions of resource conservation— namely, how do people make decisions in land management and how do they translate into policy? A subsequent tour of duty at the Center for Rural Strategies in Tennessee highlighted the diversity of rural issues and the challenges, especially in changing the perception of rural communities. The power of communications and community leader-driven advocacy, especially in Black belt and Native nations, became paramount, particularly when communities are economically depressed. There is so much knowledge in local leaders, and natural resource conservation flows through all the issues rural communities face. Telling their story became her passion.

Graduate work at Virginia Tech helped strengthen Mary’s focus on the dynamics of human behavior in environmental work, and she realized this necessarily involved agriculture. She wanted to get more into agricultural working lands and put her passion for coalition building to work. Building power and strength in place-based communities and getting rooted in trust building among all land stakeholders was her new call. With her new position with Virginia Tech Extension, the Virginia Soil Health Coalition had an advocate, a leader to help bring a burgeoning organization together.

The Virginia Soil Health Coalition is a collaboration of soil scientists, policy advocates, practitioners, and farmers seeking to further soil-health practices across Virginia. The Coalition’s work is, however, about much more than fostering soil-health practices. Their work is more complex than just adding cover crops and no till; it takes a systems orientation and working with collaborators on the more intangible aspects of partnership, such as strategic planning and evaluation. Where do you start? There are so many intangibles, so where do you draw the lines of where you are having an impact and how do you record the results you do not see, such as a general awareness of soil practices among the greater population? And how do you get more people on board, addressing them where their actions are, where they live, whether they are advocates, gardeners, or farmers?

Working with agencies and core nonprofits—NRCS, Extension, Chesapeake Bay Foundation, Conservation Districts, Forage and Grassland Coalition, and many more—the Coalition currently has about 35 partners. There is a seat at the table for all who have this vision of soil health, and it is a vast network. Mary’s job is to make the Coalition, through advocacy and education, accessible to all involved. “There is a lot going on in Virginia related to soil health,” she said, “but the partners are spread so thin.” With a goal of knowing and supporting what each group is doing in the Coalition, the intangibles become more evident. The synergies between each disparate organization result in more collaboration, more conversation, and more farmers implementing practices that, on their own place and according to their own needs, hold more water in the soil, keep nutrients out of the bay, and in turn increase the productivity and economic resilience of Virginia agriculture.

In the fall of 2021, Soil for Water entered the scene. The Virginia Soil Health Coalition was well set, through connections with Virginia Tech Extension, a core Soil for Water partner, to serve as a hub to facilitate a broader partnership across Virginia. Soil for Water is furthering the adoption of regenerative grazing practices that keep water in the soil and the Coalition is key to this success. Each member of the Coalition has connections already solidified, making communications and cross-pollination among groups more productive.

The focus on regeneration is crucial. According to Mary, the idea of regeneration goes beyond the soil component. It is about building more life into something. “We have such diverse partners, and we do not have a comprehensive definition for soil health. Rather, it is what a partner brings to the table that is important, for each has a different, though corresponding, definition…There is no check box of what to do in regenerative agriculture, and it is challenging but exciting. Defining regenerative agriculture is difficult, a buzzword we must move beyond toward a focus on more life in the soil and more widespread consideration of soil health,” Mary said. She invites us to “come together around ambiguousness” in this journey of regeneration. Again, the intangibles. I want to be engaged; how do I do that? Who are we reaching outside the Coalition? If Mary is right, engaging and knowing who to go to, and instilling a more common language and understanding of soil health among the broader population, is key. Building a spark and fostering energy among the myriad layers of influence in the community. This is the real work of coalition building.

So, what is the level of interest and commitment in Virginia to regenerative agriculture? “It is high, but maybe that’s my hope,” she said. “Maybe people don’t call it regenerative, but that is their perspective.” And maybe it is a little easier on a smaller scale. The biggest farms in Virginia are on a smaller scale than those in the West and Midwest, so it can be easier to implement certain practices, such as cover crops and no-till. “There are many progressive farmers in Virginia; there is energy and momentum. Who knows how good a particular farmer’s soil is, but they are thinking about it,” and that’s the point to start from.

“So much of state leadership is pushing for it [soil health, regenerative agriculture], so much cost-share is available on a state level. Even if some farmers will never apply for cost-share funding to implement a practice, it does trickle down.” Awareness is growing and to Mary, that is the point of the Coalition. “There is wide interest in Virginia, but the implementation piece needs work, especially on the economic front, because more farmers are paying attention and have numbers around this. It can be a strong incentive for others to adopt soil health practices.”

I asked Mary at the end of our conversation what advice she would give to a farmer interested in making a change to his soil-health practices. She responded that she would advise them to pursue farmer-driven resources, and farmer-to farmer-networks, and, importantly, to open the space for others to learn from the failures of their peers. “There is lots of innovation out there, but it is a slow process, and we are always pushing for the next step. People don’t get into farming to get rich, but they do need to make money and minimize risk. Most farmers want to learn and experiment but don’t want to risk their bottom line.” In Virginia, there is a focus on the bay and soil quality, and soil quantity and water capture are almost forgotten. This is an important paradigm for her producers and practitioners to realize, not to mention economics.

This focus on water capture and economics is what the Soil Health Coalition and Soil for Water are good at. Our common goals are connecting and networking, telling stories, and helping people imagine their own future.

Soil for Water and the Virginia Soil Health Coalition are sharing events and building capacity because there is so much overlap between them. We can leverage our work to reach a bigger audience. “We are working toward same goal, which is all that matters,” said Mary. “Let’s make it happen.”

Tracking Soil Moisture and Evapotranspiration: The Satellites Are Coming!

By Mike Morris, NCAT Southwest Regional Office Director 

A few months ago, I was given the enjoyable assignment of updating the 2006 ATTRA publication Soil Moisture Monitoring: Low-Cost Tools and Methods. I was curious to learn what had changed in the world of soil moisture monitoring and irrigation scheduling over the past decade or so.

Now, as always, you can do a pretty good job of checking your soil moisture with a shovel, the “feel and appearance” method (no cost), a hand push probe ($30-$70), or tensiometers ($50-$150 apiece). But if you’ve got anywhere from a few hundred to a few thousand dollars to spend, I learned that there are some interesting new options to consider.

Browsing around the Internet, I learned that data logger setups have evolved and are now available in many wireless configurations. A data logger is a device, usually powered by batteries or a solar panel, that records data at intervals ranging from every few minutes to every few hours. Data loggers can be hooked up by cables to buried soil moisture sensors, automatically recording your soil moisture and storing months or years of data that can be downloaded at your convenience or sent directly via the Internet to your phone or laptop, in real time.

Most surprising of all was what I learned about satellite imagery. In 2006, using satellite imagery to estimate evapotranspiration (ET)—the combined effect of evaporation and transpiration—did not exist in any meaningful way. The closest thing we had was publicly-available weather station networks like the Bureau of Reclamation’s AgriMet network for the Pacific Northwest and the California Irrigation Management Information System (CIMIS). These networks provide estimates of current and historical ET, although they have some real limitations, not least of which is the fact that the nearest weather station may be dozens or even hundreds of miles from your location.

Today, satellites are rapidly entering the mainstream. Among other advantages, satellite images can show soil moisture conditions over an entire field or farm. For a few years now, companies like IrriWatch have been providing satellite-based irrigation recommendations for an annual subscription cost of several dollars per acre. Then, in 2021, OpenET burst onto the scene.

Developed by NASA, the Environmental Defense Fund, the U.S. Geological Service, the USDA Agricultural Research Service, and other partners, OpenET uses NASA satellite data (including things like leaf temperature, leaf size, and solar radiation) along with meteorological, soil, and vegetation datasets, to provide readily available satellite-based ET estimates for the entire western United States. You see a map, in familiar Google Earth layout, and can zoom all the way down to field scale, reading ET estimates for millions of individual fields or at the quarter-acre resolution of satellite data. You can also draw shapes on the map and see monthly and annual ET values within those boundaries.

The maps are stunning, and you owe it to yourself to check it out. I found the site extremely user-friendly. It took me only about 15 minutes to set up a password and start zooming around the maps and looking at ET levels in almond orchards, wheat fields, and pastures around the country. Best of all, everything in the OpenET Data Explorer is free to view. A goal of the project is to keep the data free and easily available, although some users who need large-scale access will eventually need to pay.

To learn more about affordable soil moisture monitoring options, download the free, newly updated ATTRA publication Soil Moisture Monitoring: Low-Cost Tools and Methods. And if you try OpenET, post a comment at the Soil for Water Forum and tell us how you liked it.
