The Fertilizer Research and Education Program has just published its 2020 proceedings. FREP was established in 1990 through legislative action to provide funding for research and education regarding the agronomically safe and environmentally sound use of fertilizer in California. The program is part of the California Department of Food and Agriculture (CDFA), Division of Inspection Services, within the Feed, Fertilizer, and Livestock Drugs Regulatory Services branch. At the website you can review the fertilizer guidelines for many of the crops grown in California.
