The warm January weather and predicted rainfall have placed a large swath of Wisconsin -- including Door and Kewaunee counties -- under the risk of pollution from animal manure runoff.
That's according to the state's runoff risk advisory forecast, which places much of the state at high risk of runoff over the next 3 to 10 days.
Department of Natural Resources officials are encouraging farmers to hold off on manure application until the risk lowers.
The risk advisory forecasts are updated three times a day by the National Weather Service. They're part of the Wisconsin Manure Management Advisory System agriculture officials have put in place in recent years to help farmers know when conditions are right to spread manure on their land.
