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.

Partners unveil first on-farm robotics incubators
Opening in Salinas and Merced in 2025, Reservoir Farms will drive ag innovations in automation robotics
The Reservoir, a nonprofit building tech incubators across California, and partners Western Growers Association, University of California Agriculture and Natural Resources, Merced College, Hartnell College and venture capital firm HawkTower have announced the creation of the first-ever on-farm robotics incubators, Reservoir Farms.
Unveiled during a press conference at the FIRA USA 2024 robotics conference in Woodland, Reservoir Farms are set to open in the Central and Salinas Valleys in early 2025. This pioneering initiative significantly shifts how agricultural technology innovates through real-world testing environments, world-class resources and critical industry partnerships.
California agriculture faces critical challenges, including labor availability and cost, import competition, increased regulation, water scarcity, and climate-related challenges, including extreme weather. These challenges have spurred significant advancements in agricultural precision, automation, mechanization, and robotics in recent years.
Despite advancements, early-stage agtech projects lack critical ecosystem support, like connecting directly with growers, testing and validating their solutions, and accessing dedicated shop space and farmland. These gaps hinder capital efficiency and the development of critical solutions that meet the agricultural sector's needs.
Initial projects at the incubators will focus on early-stage agricultural innovations in automation and robotics, including rovers and drones, that accelerate the development of breakthrough solutions to the opportunities and imperatives faced by California farms producing high-value specialty crops, such as labor shortages, profitability, and adopting climate-smart technologies.
Western Growers Association, a key advocate for advancing agricultural innovation, will provide financial and operational support as an anchor partner.
Anchor educational partners like UC ANR, Hartnell College, and Merced College will play a crucial role in innovation and workforce development, preparing the next generation of agricultural researchers, professionals, and innovators to drive the future of farming in California.
HawkTower, a venture capital firm investing in early-stage startups developing breakthrough innovations for California's environmental and industrial imperatives, is also an anchor partner.
“The launch of Reservoir Farms is a critical step forward in ensuring the future resilience of California's agriculture and across the Central Coast and Central Valley,” said Danny Bernstein, CEO of the Reservoir and managing partner of HawkTower. “By placing incubators directly on the farm, we enable innovators to test, iterate, and scale solutions in real-world conditions as a more immediate path to advance farming communities.”
A new model to incubate agtech innovation
The idea for Reservoir Farms emerged from extensive industry research and consultations with over 50 organizations in the specialty crop sector. Key insights uncovered critical gaps in startups' access to real-world testing environments, shop space, and direct relationships with growers – factors severely hindered capital efficiency and posed a formidable barrier to innovation.
“Our goal is to eliminate the friction points that have historically slowed down the development of new agtech solutions,” said Walt Duflock, senior vice president of innovation at Western Growers Association. “Reservoir Farms offers a new model, where startups can work side-by-side with growers to test their technologies, iterate in a low-stakes environment, and build scalable solutions to improve agriculture's operations.”
Initiative to support thriving agtech ecosystem and job creation
The Reservoir Farms initiative also reflects a broad-based collaboration between key educational institutions, industry players, and local communities to ensure the next generation of agricultural professionals is equipped with the skills needed to support the region's growing agtech sector.
Supporting partners include Central Coast Small Business Development Center (SBDC), Communities Organized for Relational Power in Action (COPA), Digital NEST, Farmhand Ventures, Merced County Farm Bureau, Milano Technical Group, Monterey Bay DART (Drone Automation & Robotics Technology), Monterey Bay Economic Partnership, Monterey County Farm Bureau, Tesserakt Ventures, and The VINE.
“As robotics and automation become more integral to California agriculture, it's essential to have facilities like Reservoir Farms embedded within the farming community,” said Gabriel Youtsey, chief innovation officer at UC ANR. “By bridging the gap between lab-based research and real-world application and accelerating tech transfer, Reservoir Farms can help build the workforce and technology needed to address the critical challenges on the farm, from labor shortages to climate change.”
Focus on specialized services and real-world testing in California's agricultural heartland
Reservoir Farms will open its first two locations in Salinas Valley and Merced in the first quarter of 2025. Participants can lease testing fields and shop space without the burden of multi-year leases, giving them the flexibility needed to scale. The incubators will offer fully equipped R&D workshops, secure storage for expensive equipment, and customized, pre-planted specialty crop fields for testing.
These facilities will be complemented by Reservoir Farms' co-working spaces, meeting rooms, and a robust demo day schedule designed to connect startups with growers, investors, and other key stakeholders.
In addition, the Western Growers Association's validation process will provide startups with a quantitative “scorecard” that offers crucial metrics on scalability, efficacy, and financial viability. This validation, combined with UC ANR's field testing, will help startups refine their products and receive a critical stamp of approval that builds trust with growers and ensures a smoother path to commercialization.

UC ANR project to help underserved farmers in SoCal with land ownership
San Diego County has more than 5,000 small farms but less than 2% are operated or owned by Black, indigenous, or people of color – including those of Asian, Hispanic or Native Hawaiian/Pacific Islander descent, according to the 2022 Ag Census.
The reasons vary, but historically, multiple marginalized communities of color have not received the same opportunities or support for land ownership or management as their white counterparts.
Chandra Richards, University of California Cooperative Extension land equity academic coordinator for the Southern California region, is identifying barriers to equity when it comes to addressing land access, tenure, management and opportunities to increase the diversity of land managers and land ownership in the region.
Richards is the principal investigator for the Climate Action and Land Equity (CALE) project administered through UC Agriculture and Natural Resources and funded by the Department of Conservation. CALE aims to engage historically underrepresented communities in coalition building, capacity assessment and climate action planning. CALE elevates knowledge about the challenges and opportunities to land access and management for a diversity of land managers.
Among the challenges is land tenure, an established agreement between a landowner and tenant, outlining the purpose and use of the land over a period of time. However, when landowners decide to sell their land, these agreements are at risk of being null and void, forcing the tenants to renegotiate or discontinue their operation.
Land tenure leases for under five years are considered short-term, which are common in Southern California. For small, new and under-resourced farmers, landowner turnover doesn't just threaten their business plan but their livelihood.
For small farmer Byron Nkhoma, who leases land in Ramona to grow leafy greens and vegetables, the possibility of losing land is a constant worry. Since 2015, Nkhoma and his wife, Joyce, have been renting four of 20 acres to establish Hukama Produce. Over nine years, they have had two landowners. Before the land was sold to his current landowner, Nkhoma said he considered buying land, but the process proved more challenging than he thought.
“What it takes for someone like Byron to find a place to farm and establish a food system is an extremely involved process,” said Richards. “It's not just learning how to obtain land, it's also about managing that land so it can be used for years and generations to come.”
Originally from Zimbabwe, Nkhoma is adamant about taking care of the land he leases and has applied knowledge from his home to ensure resilience. Hukama Produce prides itself in improving environmental health through sustainable farming practices such as compost and mulch application, drip irrigation and low till. An important pillar of the CALE project includes building capacity and providing technical assistance toward land conservation and climate resiliency.
In addition to land tenure, money and time are stressors for small farmers. When they are not working on the farm, Nkhoma and his wife are researching and applying for grants to improve their soils and protect their crops from pests. However, many grants for which Hukama Produce is eligible often have pressing deadlines that demand their immediate attention – cutting into valuable time that could be spent tending to the land or selling at farmer's markets.
Two of Hukama's goals include building and sustaining trust in the market and growing their operation. By partnering with Richards, Hukama Produce has direct access to technical assistance focused on grant writing and conservation to increase ecosystem health and build tenure.
Agricultural land tenure is the arrangement, rights, and responsibilities centered around use, management, and ownership of agricultural land and resources. Building land tenure means that farmers have a stable place to grow their crops and build environmental sustainability without risk of having to move their operations.
While the CALE project boosts support for historically underserved community members hoping to own or manage land, it prioritizes land use for food production as a reinvestment into the greater community.
Eager to bring realities like Nhkoma's to light, Richards partnered with Keith Nathaniel, UCCE director for Los Angeles County, who co-coordinated the Western Extension Leadership Development conference held in San Diego the week of Sept. 23-27. WELD unites Cooperative Extension faculty, agents, advisors, educators and specialists from the western region of the United States for a two-year leadership development program.
While in San Diego, WELD participants joined Richards for a tour of Hukama Produce and learned directly from Nkhoma about opportunities and threats as a small farmer. The tour ended with participants in a circle, sharing how their professional roles can offer support to Hukama Produce and other small farms.
“We grow food so that we can feed the community,” said Nkhoma. “When we feed others, we build relationships. That's what ‘hukama' means – to grow relationships.”

Investments in farm-to-school program stabilize farms, expand climate-friendly farming practices
Small and midsize farms, women and BIPOC farmers especially benefit
A new report reveals that California farmers participating in the state's Farm to School Incubator Grant Program are increasing sales of fresh, local and organic produce, meat and dairy products to schools, according to researchers evaluating program impacts. The report found that 57% of the program's farmers made sales to schools between April and September 2023, representing an average of 33% of their total farm revenues. All food producers funded by the Farm to School Grant Program state that they use or plan to use climate-smart agricultural practices in their operations during the grant period.
While existing research shows that kids who engage with farm-to-school programs eat more fruits and vegetables, are more willing to try healthy foods, and even perform better in class, the California farm-to-school evaluation project examines a gap that most farm-to-school research hasn't addressed: how local purchases from schools affect the agricultural sector and the environment.
The report found that the investments are flowing primarily to the farmers the state seeks to support through this program: Of the 50 producer grantees evaluated in this report, 42% are owned by people who identify as Black, Indigenous and People of Color, and 62% are owned by women. Nearly all (94%) are small to midsize operations.
Three producer grantees revealed that the Farm to School Incubator Grant Program funding likely prevented them from going out of business. “This grant … has and will enable us to do things on the farm that would probably take us a decade to do but we'll be able to do that in one or two seasons. So [it] really moves us forward a lot,” noted one farmer.
Beth Katz, a lead researcher and executive director of Food Insight Group, said, “Farmers are expanding their relationships with local school districts, increasing their sales to schools, investing in infrastructure and staff, and forming new relationships with food hubs that can help them with the often complex purchasing requirements unique to school food. While we're still at a very early stage of understanding the impacts of these investments, we're beginning to see patterns emerge.”
A Humboldt County farmer noted that food hubs, which are also supported by the grant program, are critical to their success in accessing the school food market: “[The food hub] is really a huge game changer to be able to make that one drop in town, even though it's an hour away, rather than going to [several school sites] and just making all these little drops. That's been one of the ways that it's very . . .appealing to us as a farm to participate.”
The report also examines the potential for environmental impacts through direct investments in farmers who use climate-friendly farming practices.
“I'm inspired by the potential for the farm-to-school program to support farmers using environmentally beneficial practices like reducing pesticides, planting cover crops and growing organic — and to help farmers expand or adopt these practices. It's essential these farmers have a market for what they grow to see durable environmental benefits,” said Tim Bowles, who is leading the environmental impacts assessment for the evaluation team and is an assistant professor in the Department of Environmental Science, Policy & Management at UC Berkeley and lead faculty director of the Berkeley Food Institute.
“We're also seeing farms actually expand their acreage in order to sell to schools, suggesting this is a desirable market. We're investigating the environmental impacts from these investments, especially for climate,” Bowles said.
As with many new programs aimed at building out long-delayed infrastructure, school food systems improvement demands a deep-rooted approach.
“The challenges around changing a complex school food system are substantial,” Gail Feenstra, a pioneer in farm-to-school research and co-lead on the project from UC ANR stated. “Decades of research shows the value to children from fresh, locally sourced food. However, what is becoming more clear from this research is that long-term investments in the full farm to school system are crucial. Without regional-level infrastructure, staffing, aggregation and distribution in place to support getting that locally grown food from farms to the schools and kids, we'll have challenges moving the needle.
"Fortunately, the state's strategic and innovative investments in the entire farm to school supply chain – meaning funding for school districts, farmers and also their regional partners, combined with support from CDFA's regional staff – are beginning to address those long-standing challenges.”
