Welcome to the Office of Indiana State Chemist

The Indiana State Chemist is charged with administering several agricultural laws involving animal feeds, fertilizers, pesticides and seeds. The goals of these laws are to ensure truth-in-labeling, food safety, user safety and the protection of our environment.


It is with great sadness that we report that long-time OISC fertilizer secretary, Cyndy Anderson, passed away on December 9, 2016. Any correspondence with her should be directed to Matt Pearson.
