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 and descriptions of relevant research results for consultants, growers and crop advisors.
- Crop Fertilization Guidelines--Quickly access nutrient requirements for a distinct crop in a specific region of California and obtain the proper plant nutrient fertilizer rate suggestions that will not reduce yields and will potentially 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). There is also a Nitrogen Management Specialty available to Certified Crop Advisors looking to provide nitrogen management planning services to their clients, including certifying Irrigation and Nitrogen Management Plans (INMP) for California farmers and ranchers.
- CropManage--Online database-driven tool to assist growers and farm managers in determining water and nitrogen fertilizer applications on a field-by-field basis.
