Nitrogen Fertilizer Restrictions Began September 1
Where does the restriction apply?
The application of nitrogen fertilizer in the fall and on frozen soil will be restricted in areas vulnerable to groundwater contamination. This will also apply to Drinking Water Supply Management Areas (DWSMAs) with elevated nitrate levels. Vulnerable groundwater areas include coarse textured soils, karst geology, and shallow bedrock.
