Funding Resources

  • Healthy Soil Program. California Department of Food and Agriculture. The HSP Incentives Program provides financial incentives to California growers and ranchers to implement conservation management practices that sequester carbon, reduce atmospheric greenhouse gases (GHGs), and improve soil health.
  • Environmental Quality Incentives Program. USDA Natural Resources Conservation Service. The Environmental Quality Incentives Program (EQIP) is NRCS’ flagship conservation program that helps farmers, ranchers and forest landowners integrate conservation into working lands.
  • Seeds for Bees. Project Apis m. (non-profit organization). Seeds for Bees encourages the use of cover crops to increase the density, diversity, and duration of bee forage in California orchards, farms, and vineyards, while improving soil health.
