Organic Input Material Program
The Fertilizing Materials Inspection Program (FMIP) is an industry funded program that ensures consumers receive fertilizing materials that meet the quality and quantity guaranteed on the product label. Investigators located throughout the state conduct routine sampling and inspections, respond to consumer complaints, and enforce the laws and regulations that govern the manufacturing and distribution of fertilizing materials in California. Environmental scientists and Research Analysts review product labels for misleading claims and compliance with the California Fertilizing Materials Law and Regulations.
The Organic Input Material (OIM) Program registers fertilizing materials to be used in organic crop and food production. The program is mandated by the Legislature and supported by the industry. Products claiming to be appropriate for use in organic production are verified to comply with the California Fertilizing Materials Law and Regulations and USDA National Organic Program Standards. Effective January 2012, OIMs distributed in California shall be registered with the FMIP.
