Prevent Manure Spills - Best Practices for Wisconsin Farms
All farms in Wisconsin, regardless of size, are required to report manure spills or runoff that could harm state waters. If a spill occurs, call the 24-hour spill emergency hotline at 1-800-943-0003 immediately.
Be Prepared for Spill Emergencies
A proactive approach to spill response is key to minimizing damage. Farmers should develop a response plan that includes key contacts and clear steps to contain spills. Essential resources include:
- Emergency Response Plan (UW-NPM)
- Emergency Response Contacts (UW-NPM)
- Plan for Nutrient Management
Creating a Nutrient Management Plan (NMP) helps farmers determine when and where to spread manure efficiently. A well-structured plan can improve soil health, lower fertilizer costs, and prevent runoff pollution. Resources for nutrient planning include:
- DNR Nutrient Management Planning
- DATCP Nutrient Management Planning
- NRCS Comprehensive Nutrient Management Planning
Preventing Manure Runoff and Spills
Proper manure management safeguards water quality and maximizes its value as fertilizer. Heavy rainfall and snowmelt can increase runoff risks, making prevention crucial. Farmers can take the following steps:
- Use the Runoff Risk Advisory Forecast (RAFF): This tool provides daily maps that assess the risk of manure runoff across Wisconsin based on precipitation, soil conditions, and terrain.
- Follow Winter Manure Spreading Guidelines: CAFOs are required to avoid surface manure application on frozen or snow-covered ground during February and March. Smaller farms should also follow these best practices to reduce runoff risks.
- Seek Alternative Storage Solutions: Contact County land conservation agents, agronomists, or manure haulers to explore alternative storage options. Safe solutions may include stacking manure in low-risk areas away from water sources and steep slopes.
By implementing these strategies, Wisconsin farmers can enhance nutrient management, prevent pollution, and protect local water resources.
