Preparing soil for winter can protect soil health
Farmers placed clumps of soil into metal mesh baskets, submerged the baskets into jars of water, then watched to see if their soil held together. The slake test, conducted at the Soil Health Field Day in Woodland, measured soil health. Healthier soil, which contains more organic matter and bioactivity and can better support plant growth, stays intact.
“Participants said that it was particularly useful to see the slake test on a variety of soils to better understand the nuance of how soil health management practices such as cover cropping and reduction of tillage intensity could affect soil aggregation,” said Sonja Brodt, UC Sustainable Agriculture Research and Education Program coordinator for agriculture and environment, who attended the field day alongside Vivian Wauters, SAREP project scientist.
Technical assistance providers, farmers and other soil health professionals gathered at the Center for Land-Based Learning on Nov. 19 to learn about preparing soil for winter with a specific focus on how soil health impacts soil structure, as well as the ability for water to move through soil as opposed to puddling or running off a field.
“Soil with stable aggregates can withstand this submersion and stay intact, whereas a soil with poor aggregation will fall apart in the water,” Wauters explained.
This in-field test can produce dramatically different results, where poorly aggregated soil colors the water, while the stable, aggregated soil will leave the water column relatively clear.
Farmers were invited to bring their own soil samples to perform slake tests at the field day. Kabir Zahangir, USDA Natural Resources Conservation Service regional soil health specialist, compared soils from different management practices and discussed how to assess aggregate stability and soil water infiltration.
Attendees also heard from experienced growers Scott Park of Park Farming Organics and Andrew Brait of Full Belly Farm, who described how they assess soil health on their farms.
By collaborating with others, Brodt said farmers and researchers are achieving benefits through learning together in real time. “We will also be able to benefit from aggregating soils data from across regions to begin to develop a statewide soil health database, which is a critical step in order for researchers to be able to determine relationships between farming practices and soil health outcomes under California conditions in the future,” she said.
Slake tests can be performed on soil from one's own backyard, garden or farm to better understand the health of the soil. Additionally, the NRCS principles of soil health – minimized disturbance, maximized biodiversity, maximized soil cover and maximized living roots – can be applied across all scales, though the specific practices will vary based on the type of yard or farm as well as the local climate and soil type.
Brodt and Wauters, who coordinate the California Farm Demonstration Network, emphasize that it's important to have local examples of innovative conservation practices across the state so people can see what is working to protect and enhance the soil health in their specific region. They encourage farmers and technical assistance providers to visit https://www.calfarmdemo.org/ to find local farms that are showcasing innovative practices. Farmers interested in being a farm demonstration site are also encouraged to contact Brodt (sbbrodt@ucanr.edu) and Wauters (vwauters@ucanr.edu).
They hope to continue to support the learning and sharing of knowledge around climate-smart farming practices to help California's farmers adopt climate beneficial practices.
“CDFA has funding programs, such as their Healthy Soils grants, that farmers in our network can apply for to help cover the costs of implementing soil health practices,” Brodt said.
Current work on the California Farm Demonstration Network is funded through a University of California Office of the President Climate Action Grant.

Warner becomes UCCE livestock and natural resources area advisor
Excited to serve the community in which she grew up, Warner will help ranchers solve their most pressing issues. Currently, small ranchers with up to 15 cows, for reference, need support establishing their operation. Commercial ranchers, however, are interested in technology and developing research that will help improve health and nutrition of their cattle.
“If a rancher's animals aren't healthy, they can't make money,” she said. “If they can't make money, they can't support their family or their business.”
Despite profitability being “priority zero” for consumers, Warner said that staying in business and/or expanding business operations is a primary goal for many ranchers. As an advisor, she's excited to not only support ranchers' endeavors to increase profits, but challenge consumers' perspectives on the matter, too.
Although a new advisor, Warner has worked for UC Cooperative Extension since 2022. First hired as a staff research associate at the Sierra Foothill Research and Extension Center in Yuba County, Warner said her research work has focused on nutrition and health of beef cattle, oak regeneration and rangeland management.
Warner earned a master's degree in animal science from Oklahoma State University and a bachelor's in animal science from California State University, Chico. While her academic training will certainly be useful, Warner said that the mentorship she's received from colleagues has been instrumental during her transition.
She succeeds Dan Macon, UCCE livestock and natural resources advisor, who transferred to UCCE in Calaveras County.
Warner is based at the UCCE Placer-Nevada counties office in Auburn and can be reached at alnwarner@ucanr.edu.

Ask a rancher: Surveys draw on hard-won wisdom for surviving drought
Roche team lands $1 million to help ranchers stay strong
California ranchers benefit when they plan ahead for extreme weather variability, according to rancher surveys and interviews conducted by a team headed by Leslie Roche, a professor of Cooperative Extension in the UC Davis Department of Plant Sciences.
But while wise planning and climate-smart adaptations helped ranchers survive the state's record-breaking 2012-2016 drought, those strategies by themselves were not enough, ranchers reported. Nearly 50 ranchers shared their experiences, and their collective wisdom is summarized in a paper written by Grace Woodmansee. She completed her master's degree with Roche and is now a UC Cooperative Extension livestock and natural resources advisor for UC Agriculture and Natural Resources in Siskiyou County.
Building on that work, Roche and members of the statewide team have landed a $990,000 federal grant to help ranchers stay strong. The team includes colleagues from the University of California Agriculture and Natural Resources and partner organizations. The project draws on members' diverse expertise and regional knowledge rooted in UC Cooperative Extension, while at the same time linking up with trusted networks at the local level.
Both Woodmansee's paper and the new grant are based on more than a decade of surveys and interviews with ranchers and other agriculturalists. That work all points to the economic and social barriers that hinder producers from adopting the climate-smart practices that could help them stay profitable amid the changes to come.
“It's really important to listen to agricultural producers – the people who live and work on the land – and draw on their experiences to develop practical solutions,” Roche said. “Extension can play a key role in sharing this valuable knowledge statewide, so others can learn from it and, hopefully, apply it to navigate their own challenges.”
Partners on the project include individual livestock producers, statewide livestock organizations, local conservation organizations and local agencies. Programs like this could become an example for ranch managers across the American West.
Cattle is California's No. 3 agricultural commodity, with cattle and other livestock worth about $3 billion in 2021, the state Department of Food and Agriculture reported. In addition to facing climate change, the sector is beset by rising costs, high interest rates, wildfire impacts and land use pressures. These additional challenges make it crucial for people managing the state's 14,000 livestock operations – counting beef, sheep and goats – to take steps now to survive future droughts.
Rangeland drought strategy: Mix up the livestock
In the past 12 years, ranchers have increasingly adopted sustainable agriculture practices to cope with drought and other threats, Woodmansee and colleagues found.
A key finding from the surveys is the enormous benefit amid drought of grazing more than one kind of animal on rangelands, Woodmansee wrote. Although most ranchers interviewed grazed only one species during the drought, typically cattle, the few who mixed up their livestock reported doing better economically. Because they have different grazing habits, stock such as sheep and goats can take advantage of different kinds of forage and broaden a rancher's economic base.
In addition, ranchers who used genetic information to think ahead about culling their herds, when that step became necessary, were left with a stronger remainder, Woodmansee wrote.
Ranchers also found it was important to have plans both for preventing problems and reacting to them, Woodmansee added. But surveys done ahead of the 2012-2016 drought, and interviews done four years in, also revealed that only a little more than half of ranchers had planned ahead.
“There is a substantial opportunity to increase preparedness by aiding ranchers in developing drought management plans,” Woodmansee wrote. But she advised, “drought plans are not ‘one size fits all,' and policy must be designed to support drought adaptation and mitigation strategies at the ranch level.”
Grant part of nationwide effort
Roche and team's $990,000 grant comes from the United States Department of Agriculture through the National Resources Conservation Service. It's part of a $22-million, nationwide effort to help American ranchers overcome these and other barriers they face to adapting. Based on all they've learned through the surveys and interviews, the team is now launching a comprehensive education, outreach and training program. Their own wide range of expertise and networks reach deep into ranching communities, and they'll leverage those, too. 
UC Cooperative Extension will have an important role in that work, as a trusted source of information. Training also will embrace conservation planners and technical service providers who work with ranchers.
“Activities will include workshops, field tours and demonstrations on conservation practices to address local natural resource concerns,” the team wrote in their proposal. Their work also “will target opportunities to support underserved communities, including new and beginning ranchers.”
They'll also add resources specifically about the state's grazing lands to the California Climate Hub, a website developed by USDA to provide the latest information to help producers statewide adapt to new climate realities.
People trained in all these areas must be brought up in the ranks: The project calls for networking, mentoring and hands-on learning to spark career choices among young people, and grow skills among beginning ranchers and early career natural resource professionals.
Scientists co-leading the project are Tracy Schohr and Dan Macon of UC Cooperative Extension; Roselle Bush and Gabriele Maier, both UC Davis assistant professors of Cooperative Extension; and Steven Ostoja, California Climate Hub director. The project will provide opportunities for a broad range of UC ANR colleagues as well, Roche said.
