The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) reminds farmers and manure applicators to check the runoff risk advisory forecast before spreading manure. This tool helps assess the potential for runoff based on weather conditions and soil temperature. Access the tool at Manure Advisory System.
The runoff risk advisory forecast provides maps showing short-term runoff risk. These maps consider soil saturation, temperature, and precipitation, covering 1.5 square-mile grids. Updated four times daily, they use the latest data from the National Weather Service.
“When applying manure, it’s essential to have a nutrient management plan that identifies proper application rates and locations,” said Mark Witecha, DATCP soil and watershed conservation section manager. “The runoff risk advisory helps farmers make informed decisions and reduce runoff by identifying the best times to spread manure based on current conditions and short-term weather forecasts.”

Alternatives to High-Risk Manure Spreading
Farmers can contact their crop consultant or county land conservation office to identify alternatives to high-risk spreading. Larger farms with a permit can also consult the Wisconsin Department of Natural Resources (DNR). These professionals can help identify low-risk fields and recommend practices like stacking manure safely.
Manure Spill Requirements
DATCP urges manure haulers and drivers to prioritize safety when traveling on roadways to prevent spills and protect health and the environment.
“Operator error is a major cause of manure spills between the farm and field,” said Kevin Erb, UW-Madison Division of Extension conservation professional training program manager. “Taking time to ensure safety and maintain equipment reduces spill risks. While accidental spills aren’t illegal, failure to report and clean them up is.”
All agricultural and livestock operations must report spills or runoff potentially affecting surface or groundwater to the DNR’s 24-hour emergency spills hotline at (800) 943-0003. For more prevention and planning information, visit Manure Spill Prevention.
