Agricultural nonpoint source pollution
Nitrate Webinar Series:
This series touches on the science and economics around a number of workable approaches for farmers shown to minimize nitrogen losses to groundwater.
Nonpoint source pollution (or "runoff pollution") of Wisconsin’s waters comes from many sources, including agricultural operations and croplands. When it rains or snow melts, that water may be polluted through contact with manure, feed leachate or milkhouse waste. When this polluted runoff enters our lakes, rivers or groundwater, it can cause significant pollution. Runoff sediment or fertilizers used on croplands can also cause water pollution during rain or snow melt. Good farming practices can reduce this polluted runoff and protect water quality.
