During which period is manure application prohibited?

The prohibition on manure application during the period of December 15 to the last day of February is grounded in environmental protection measures designed to prevent nutrient runoff into waterways, which can lead to water quality degradation. During this winter period, the ground is often frozen or saturated, making it more likely that applied manure will not be absorbed and instead run off into nearby streams and rivers during thawing, rainfall, or melting snow.

This time frame is critical as it coincides with lower crop uptake of nutrients and heightened risk of environmental impact due to the wet conditions typically present in late winter. Proper nutrient management practices aim to optimize nutrient use efficiency and protect water resources, aligning with regulatory requirements established to safeguard environmental health. Such measures are crucial in protecting sensitive ecosystems and maintaining compliance with Maryland’s nutrient management regulations.

Other periods listed in the choices either fall outside of the winter runoff risk or do not align with the established guidelines for nutrient management practices in Maryland. Understanding these timing restrictions is essential for farmers to ensure compliance and responsibly manage their nutrient applications.
