Welcome to the Office of Indiana State Chemist
The Indiana State Chemist is charged with administering several agricultural laws involving animal feeds, fertilizers,
and seeds. The goals of these laws are to ensure truth-in-labeling, food safety, user safety and the protection of our environment.
Our site has changed! The gold navigation bar directly under the header image is the primary navigation bar, and it is on every page of our website. When you visit our other sections (pesticide, feed, fertilizer, seed), you will see a gray secondary navigation bar that appears beneath the primary navigation bar for each section. Please contact the webmaster if you have any questions or comments regarding navigation of this site.
Latest News, Alerts and Other Information:
On January 7, 2014, the Office of Indiana State Chemist experienced the effects of a frozen and burst four inch water main that adversely affected all operations. The Office continues to make great strides in meeting the needs of its clients, and regaining full operational status. Some operations, especially our Laboratories, are slower to gain operational status due to losses of equipment. Still, progress continues to be made as rapidly as possible. We appreciate your continued patience as some parts of our Office are restored more rapidly than others.
