The fertilizer section regulates the distribution, storage, and use of commercial fertilizers and manure in Indiana. The Office of Indiana State Chemist (OISC) is a member of AAPFCO, the Association of American Plant Food Control Officials.
Fertilizers must be labeled truthfully and accurately. Fertilizer product label claims are reviewed prior to registration. Marketplace surveillance, sampling, and analysis ensure truthful labeling and safe products.
The Indiana Fertilizer Advisory Board is established to study the regulation of fertilizers and to advise the State Chemist on the administration of this chapter, IC 15-16-2-25. Please visit the Indiana Fertilizer Advisory Board page for information.
