Fertilizer Research & Education Program
The Fertilizer Research and Education Program (FREP) funds and facilitates research to advance the environmentally safe and agronomically sound use and handling of fertilizing materials. FREP serves growers, agricultural supply and service professionals, extension personnel, public agencies, consultants, and other interested parties. A number of FREP projects have resulted in applications and guides for growers and crop consultants, including, but not limited to, nitrogen fertilization models for crops, a nitrogen and water management production guide for coastal vegetables, and best management practices for fertilizer and water use in irrigated agriculture. See a more comprehensive list of outcomes at Nutrient Management Resources.
- FREP Research Database — The searchable database of FREP research provides access to descriptions of relevant research results for consultants, growers, and crop advisors.
- Crop Fertilization Guidelines — Quickly access nutrient requirements for a specific crop in a defined California region and obtain fertilizer rate suggestions that will not reduce yields and may help reduce fertilizer overuse.
- Irrigation and Nitrogen Management Training Program — Allows California farmers and ranchers to self-certify their Irrigation and Nitrogen Management Plan(s). A Nitrogen Management Specialty is also available for Certified Crop Advisors.
- CropManage — An online, database-driven tool to assist growers and farm managers in determining water and nitrogen fertilizer applications on a field-by-field basis.
