The California Department of Food and Agriculture is soliciting for applications for two programs: Healthy Soils Program (HSP) and Alternative Manure Management Program (AMMP). These programs, funded through the state's Cap and Trade Program, aim to support agricultural production through incentivizing practices resulting in a net benefit for the environment through innovation, efficient management, and science.

The University of California Cooperative Extension in Sonoma County received funding to assist farmers and ranchers in applying for these funds.

The AMMP program provides financial assistance for the implementation of non-digester manure management practices in California, which will result in reduced greenhouse gas emissions. These practices include solid separation, conversion from flush to scrape manure collection, increased pasture access, and construction of a compost bedded pack barn.

The program offers a maximum project award of $750,000 without the requirement of a cost share. Applications are currently being accepted and the deadline to apply is March 27^th, 2020 at 5:00 pm PT. If you are interested in this program and would like more information, visit the CDFA AMMP page.

For assistance in project development and submitting an application, contact:

Randi Black, Dairy Advisor, UCCE Sonoma County, rablack@ucanr.edu, 707-565-2648

The HSP has two components:

• HSP Incentives Program
• HSP Demonstration Projects

The HSP Incentives Program provides financial assistance for implementation of conservation management that improve soil health, sequester carbon, and reduce greenhouse gas emissions. Incentives projects are eligible for a maximum award of $100,000 with no cost share required.

The HSP Demonstration Projects showcase California farmers and rancher's implementation of HSP practices. Demonstration projects can be either data collection focused with outreach and education components ($250,000 maximum award) or just focus on outreach ($100,000 maximum award).

Applications are not yet being accepted, but are expected to open in February with the deadline for submission in April. If you are interested in this program and would like more information, visit the CDFA Healthy Soils Program webpage.

Is Compost Bedding Pack right for your dairy? 

Compost bedded pack (CBP) barns are an increasingly popular open barn design for housing dairy cattle, particularly with funding opportunities available through the California Department of Food and Agriculture's Alternative Manure Management Program. These barns allow natural resting positions and offer shelter with a reduced infrastructure cost compared to traditional freestall barns. However, proper barn design and excellent daily management are essential for successful composting and to avoid negative animal health outcomes. A successful CBP begins with three key principles: bedding, stocking density, and air flow.

Bedding

In a CBP barn, bedding is more than an absorbent lying surface for your cows. Bedding acts as the carbon source, or essentially food, for the microorganisms within the composting bed. Before deciding to construct a CBP barn, consider where and at what cost you can acquire a continuous supply of bedding material. A mixture of kiln-dried sawdust and shavings remains the “gold standard” for CBP bedding. Other bedding alternatives exist, though may require more frequent additions and result in less efficient composting. Moisture content (and not time) determines when additional bedding needs to be added. The CBP should be between 45 and 55% moisture. To quickly test moisture, grab a handful of compost material and squeeze it. If water drips out of the ball, the CBP is too wet and you should add more bedding. If the material cannot form a ball, the CBP is too dry and you can wait before adding more bedding.

Stocking Density

Animal numbers can fluctuate on a dairy. A CBP is not always forgiving to those fluctuations. Stocking rates in a CBP are driven by the urine and fecal outputs of the cows. Producers should aim to provide 125 to 150 square feet per Holstein cow. Smaller framed cows, such as a Jersey, require less space. Overcrowding the barn results in too much moisture, dirty cows, and potential for udder health consequences. High stocking rates can also pack down the CBP, restricting air flow to the microbes and reducing composting efficiency. When planning the foot print of the barn, design for the peak number of animals and not the average to ensure adequate space year round.

Air Flow

The aerobic composting process requires oxygen. Adequate air flow is not only important for cow health and comfort but also to feed air into to CBP. Designing the barn with high side walls and fans provides natural and mechanical ventilation. Proper ventilation ensures microbes are supplied adequate oxygen essential for proper composting. Limiting the air available to microbes can reduce or stop composting. Twice daily stirring of the pack (without fail!) is also essential for composting success. A field cultivator accomplishes deep aeration (10-12”). A rototiller provides more shallow aeration (6-8”) with more breakdown of larger compost chunks and a more uniform surface.

Key Points

• Is there a source of year round bedding material which is affordable and consistent?
• Add additional bedding based on CBP moisture content
• Provide 125 to 150 sq. ft. per cow (Holstein; less for Jersey)
• Design the barn for peak animal numbers
• Stir the pack twice daily, without fail!
• Ventilate barn with natural and mechanical ventilation to ensure aerobic environment for composting

Vice President Glenda Humiston introduced alumni regent-designate Debby Stegura to UC Cooperative Extension staff and their community partners and clientele in Sonoma County on Nov. 15.

After visiting Beretta Dairy, Bayer Farm Park and Gardens, Sheppard Elementary and Stuhlmuller Vineyards, Regent Stegura tweeted:  

“Blown away by @ucanr tour of @UCCESonoma work—Beretta Dairy, @UCMasterGarden, @Stuhlmullerwine, @California4H. Saw #kincaidfire reach, how to prepare better for future fires. @ucanr work benefits all of CA. Thank you!”

The retired business litigator and UC Davis alumna was joined on the tour by Anne Shaw, secretary and chief of staff to the regents, and Michael Bedard, UC state government relations legislative director.

Stephanie Larson, UCCE director for Sonoma County, led the tour, which first visited Beretta Dairy.

“It's so nice to have a dairy advisor,” Sonoma County dairy farmer Doug Beretta said, crediting Randi Black, UC Cooperative Extension dairy advisor, with providing the technical assistance he needed to apply for a grant to reduce methane emissions. 

Black, who joined UC ANR in 2017, helped four local dairies obtain grants totaling $2.5 million and said the projects propose to reduce emissions by 9,327 metric tons of CO₂ equivalent over the next 5 years, which is comparable to removing 2,028 passenger vehicles from the road for a year.

Beretta talked about the work he has done at the dairy, based on UC research, to improve water quality. David Lewis, UCCE director for Marin and Napa counties, noted that similar manure management and water-quality work is being implemented by UCCE clientele in his counties.

Discussing the hardships created by low milk prices in the dairy industry, Beretta said he appreciated UCCE's agricultural ombudsman Karen Giovannini guiding producers who want to sell value-added products through the permitting process.

From the dairy, Stegura and the group met with Mimi Enright, UC Master Gardener Program manager for Sonoma County, UC Master Gardener volunteers and Julia Van Soelen Kim, North Bay food systems advisor at Bayer Farm Park and Gardens.

Collaborating with Bayer Farm, the Master Gardeners have been expanding outreach to Spanish-speaking members of the community. In addition to all of the traditional Master Gardener outreach, the Master Gardeners in Sonoma County have been actively promoting firewise landscaping to help Sonoma County residents better prepare for wildfires. Using UC ANR materials is critical, Enright said, to assure people the recommendations are based on scientific research. 

After the wildfires in 2017, Van Soelen Kim and Enright launched a citizen science project with community partners to assess produce safety. Within days of the fire, volunteers collected 200 samples of leafy greens from school, backyard and community gardens. With funding from UC ANR and the Bay Area Air Quality Management District, they expanded testing to soil and partnered with UC Davis researchers to test eggs laid by backyard poultry, and published guidance for produce safety after urban wildfire.

After the Kincade Fire, when growers and gardeners asked if produce grown outdoors was safe to eat, Enright said UCCE Sonoma County could tell them, based on local research, it was safe to eat if consumers removed outer leaves and washed the produce and that the health benefits of eating fresh produce outweigh any trace contamination.

UCCE has been leading a coalition of community partners and government organizations to educate the community on reducing food waste and increasing food recovery. When PG&E announces public safety power shutoffs, they promote composting food that can't be eaten so it doesn't end up in a landfill.

“This kind of service in communities is not as well-known about UC as the campuses,” Humiston commented to the regent.

Across the street from Bayer Farm, Diego Mariscal, 4-H program assistant, has been collaborating with Sheppard Elementary School. It is one of several schools in the county providing 4-H afterschool clubs and other 4-H programs designed to nurture the next generation of Latino leaders. Last spring, Mariscal worked with families to build a 4-H soccer league for elementary school children. Parents, college and high school students were trained by 4-H to teach children teamwork, soccer skills and healthy eating habits. More than 200 new underserved youth participated in 4-H programs in Sonoma County during the 2018-2019 year.

A few of the soccer players, proudly wearing their green 4-H soccer uniforms, told the group what they liked about 4-H. 4-H All Star Corrianna E., who participates in the 4-H teen program, shared her experience in 4-H and expressed gratitude to the program for helping her overcome her shyness to become a strong public speaker. Corrianna's mother, Naomi Edwards, also shared her experience as 4-H Council President for Sonoma County. 

The tour's last stop was at Stuhlmuller Vineyards, where vineyard manager John Gorman told Stegura and the group that California's preeminent grape growing region relies on UCCE for sound advice to manage pests and emerging problems.

“You want to know what's a good cultural practice? Rhonda Smith has answers backed up by hard science,” Gorman said of the UCCE viticulture advisor. 

When new landowners ask Gorman for advice, he refers them to Steven Swain, UCCE environmental horticulture advisor, who advises small parcel land managers in Sonoma County on managing the land for fire and wildlife. “Without UCCE, where would they turn?” Gorman asked, adding that people from private companies may have recommendations that may not be in best interest of the land. 

Larson introduced new UC IPM advisor Cindy Kron, who succeeds recent retiree Lucia Varela. Kron is launching an IR-4 project to study pesticides for olives, which isn't a big enough market to interest private investment in research. She's also monitoring pears for brown marmorated stink bug because early detection is key to controlling the pest. Spotted lanternfly isn't in California yet, but grapes are among its favorite hosts so Kron is working with UC Master Gardener volunteers and other community members to watch for the exotic pest. 

The Kincade Fire destroyed fences and scorched the rangeland at Stuhlmuller Vineyards, forcing Gorman to sell the cattle. He showed the group where the fire failed to advance at the fire break created by the lush vineyards. As a result of the Kincade Fire, Gorman wasn't able to sell his petite verdot, chardonnay and cabernet grapes to wineries. To prove to the insurance company that smoke damaged the crop, his crew picked 30 tons of grapes for testing.

During and after the devastating fires in the North Bay, Larson, who is also a UCCE livestock and range management advisor, assisted livestock owners to gain access to their burned properties; this ensured their animals got food and water. She also organized resource meetings for landowners affected by fires, helping them apply for funding from government agencies and insurance companies for animal, forage and facility losses.

Larson also said her new grazing database Match.Graze has been well-received by ranchers and landowners in Sonoma and Marin counties who want to use grazing to reduce fire fuels. Land managers and grazers can sign up at ucanr.edu/matchgraze to hire sheep, goats, cattle and horses to manage fire fuels.

The regent tours in Sonoma Country and Fresno County were coordinated by Anne Megaro, government and community relations director. She is planning future tours for regents at UC South Coast Research and Extension Center and other locations in the spring.
