Winter Manure Application in Ohio

By Andi Anderson

As winter approaches, Ohio livestock producers face critical regulations regarding manure application. Here's an overview of guidelines and considerations for winter manure management to align with Ohio's updated regulations:

• Frozen Ground Criteria: Applying manure on frozen ground, where soil can't integrate manure or conduct tillage within 24 hours, is prohibited for permitted farms unless it's an extreme emergency.
• Grand Lake St Marys (GLSM) Watershed: The ban from December 15th to March 1st restricts manure application in this region.
• Natural Resource Conservation Service (NRCS) Code 590: This revised code applies statewide in Ohio (except to GLSM), prohibiting surface manure application on frozen and snow-covered soil, except in emergencies. Specific criteria for emergency applications include limited quantities and adherence to strict guidelines:
  • Application Rate: Limited to 5,000 gallons/acre or phosphorus removal for the next crop.
  • Field Criteria: Apply on land with 90% surface residue cover and avoid contiguous areas exceeding 20 acres.
  • Placement and Setback: Choose low-risk areas, maintain 200 feet minimum setback from water sources, and adapt to local conditions for increased setback.
  • Sloped Fields: Apply on alternating strips or contours for fields exceeding 6% slope.
• • Solid Manure Management:
  • Short Term Stockpile (NRCS FOTG 318): Keep piles for no more than 180 days, following setback distances to prevent discharge into water bodies.
  • Long Term Stockpile (NRCS FOTG 313): For piles exceeding 180 days, comply with guidelines for permanent locations, utilizing stacking facilities to prevent runoff.

For producers considering winter manure application, consulting the local Soil and Water Conservation District office is recommended. Regulations have evolved, and understanding their impact on farm operations is crucial. Stay informed to comply with these regulations while ensuring sustainable agricultural practices.
