Nutrient Management

The University of Maryland Extension Nutrient Management Program assists farmers with the Water Quality Act created to protect the Chesapeake Bay and its tributaries by applying fertilizers, animal manure, and other nutrient sources in an effective and environmentally sound manner.

Nutrient Management Plans-Farmers are required to have an up-to-date nutrient management plan written by a licensed planner. There are private consultants available to write plans for a fee, or free plans can be generated through the University of Maryland Extension. Contact your Extension office for more information on getting a nutrient management plan written.

Nutrient Voucher-Maryland nutrient applicators are required under the 1998 Water Quality Act to follow guidelines on fertilizer and manure applications. Farmers applying nutrients (synthetic or organic) to 10 or more acres of land are required to have a current Nutrient Management Voucher. Vouchers are obtained by attending an approved 2-hour training course once every three years. Farmers who are certified to prepare their own nutrient management plans are exempt from this requirement. The University of Maryland Extension offers several voucher training sessions throughout the year.
