The fertilizer section regulates the storage and distribution of commercial fertilizers in Indiana. The Office of Indiana State Chemist (OISC) is a member of AAPFCO, the Association of American Plant Food Control Officials.
The fertilizer law regulates not only the distribution of fertilizers, but also the storage of fertilizers as well. Fertilizers must be labeled truthfully and accurately and must be stored according to defined standards to prevent release into the environment.
