Reminder from The Equiery – this manure spreading policy applies to horse pastures as well.

From the Maryland Department of Agriculture

The Maryland Department of Agriculture reminds farmers that the winter ban on spreading manure and other nutrient sources on cropland, including food processing residuals (FPRs) begins December 16, 2023. Farmers may resume spreading on March 1, 2024, based on their nutrient management plan recommendations, as long as fields are not saturated, snow-covered, or hard-frozen. 

Maryland’s nutrient management regulations prohibit farmers from spreading manure and other nutrient sources on fields in winter due to the increased risk of runoff into local waterways. Farmers are required to store liquid manure sources generated on farms in structures. The department is authorized to work with livestock farmers to prevent overflows from storage structures and minimize impacts on water quality. In these instances, farmers must contact the Nutrient Management Program for emergency authorization before spreading occurs. 

Temporary field stockpiling of “stackable” poultry litter and other qualifying organic nutrient sources is allowed if the moisture content is 60% or less. Farmers may not apply stackable organic nutrient sources to fields in winter under any conditions. 

Farmers should contact their regional nutrient management specialist if they have storage concerns, questions about the regulations, or need guidance on storage requirements. For more information, please visit the department’s Nutrient Management Program website.
