Relating to: the distribution and labeling of fertilizers and soil or plant additives produced from manure. (FE)

AB 93 modifies the labeling and distribution requirements for fertilizers and soil or plant additives created from animal or vegetable manure, specifically compost and vermicompost. The bill allows producers of these manure-based products to use a "typical analysis" of their contents on labels and invoices, instead of a "guaranteed analysis" or "grade," if the claims are scientifically validated. It also exempts mixed fertilizers made from manure-based compost or vermicompost from minimum nutrient content requirements. Additionally, the bill prohibits the state department from requiring controlled experimental field tests for compost-based soil or plant additives when substantiating claims for permits.
