The Wisconsin Department of Agriculture, Trade and Consumer Protection is reminding farmers and manure applicators to check the state’s Runoff Risk Advisory Forecast before spreading manure this season.
The online tool helps determine the potential for manure runoff based on current weather, soil temperature, and field conditions. Risk maps are updated four times a day using data from the National Weather Service.
DATCP nutrient management outreach specialist Andrea Topper says nutrient management planning plays an important role in responsible manure application and protecting water quality.
State officials say farmers can also work with crop consultants, county land conservation offices, or the Wisconsin Department of Natural Resources to find alternatives when runoff risk is high.
Officials are also reminding manure haulers to focus on roadway safety and prevent spills. According to Kevin Erb with the University of Wisconsin–Madison Division of Extension, runoff incidents in late winter and early spring dropped more than 30 percent from 2020 through 2024 compared to the previous five-year period.
Any manure spills that could affect surface or groundwater must be reported to the DNR’s 24-hour emergency spills hotline.
