Bill > SB78

This bill aims to update regulations concerning fertilizers and soil or plant additives derived from manure, introducing new definitions like "beneficial substance" (something that improves plant nourishment or soil quality without being a direct plant nutrient) and "vermicompost" (composted material mixed with worm castings). A key change is that fertilizers made from composted or vermicomposted manure will have more flexible labeling requirements; for instance, if they provide a "typical analysis" (an average of the substances they contain), they won't need to list a "guaranteed analysis" (a specific minimum amount of nutrients) for plant nutrients or beneficial substances, as long as the typical analysis or other scientific methods validate the claims. The bill also modifies rules regarding the minimum nutrient content for mixed fertilizers, creating an exemption for those produced from manure-based compost or vermicompost. Furthermore, it clarifies that for compost-based soil or plant additives, regulatory agencies cannot mandate experimental field tests for substantiation and can accept typical analyses instead of guaranteed analyses for labeling and permit applications.
