New rules for fertilizer use, application and storage have been announced in Indiana. The new rules will take effect Feb. 16, 2013. Although the rules apply mainly to farmers, ag retailers are being informed of the requirements.

The new rules are designed to keep fertilizers out of waterways. The rules specify how fertilizer can be safely stored on farms until use and how far from waterways and wells it can be applied and under what weather and other conditions.

The Office of Indiana State Chemist (OISC) has posted the new rules on its Web site at

Matt Pearson, administrator of the office’s fertilizer section, said it is possible some fertilizer dealers and applicators may not know about the rules by the time they take effect. He said the office will take this into consideration.
