Lake Erie Western Basin Watershed Fertilizer and Manure Regulations

In July, 2015, new regulations became effective for fertilizer and manure applications in the Lake Erie Western Basin Watershed. Click here for a summary of the regulations and map of the watershed area.

Fertilizer Certification Signed into Ohio Law
In June, 2014, Governor Kasich signed the Ohio agriculture nutrients law which will require farmers applying fertilizer to 50 acres or more to become certified. This certification is part of a broader initiative developed by a task force convened in 2012 with several Ohio agencies participating. The task force focused on developing recommendations for improving Ohio’s waterways while maintaining the integrity of the region’s agricultural industry.

Training opportunities for the fertilizer applicator certification are available. Farmers need to be certified by September 30, 2017.
