Agricultural Nutrient Management Program

About Maryland's Nutrient Management Program

Maryland law requires all farmers grossing $2,500 a year of more or livestock producers with 8,000 pounds or more of live animal weight to follow nutrient management plans when fertilizing crops and managing animal manure. 

What nutrient management plans cover

Nutrient management plans specify how much fertilizer, manure or other nutrient sources may be safely applied to crops to achieve yields and prevent excess nutrients from impacting waterways. 

Because of their complexity, these plans must be prepared by a certified University of Maryland specialist, certified private consultant, or farmer who is trained and certified by the department to prepare his or her own plan.

Phosphorus management​

Maryland's Phosphorus Management Tool (PMT) regulations require farmers with Soil Phosphorus Fertility​ Index Values of 150 or greater to follow PMT guidelines in their nutrient management planning and applications.

Restrictions & permits

To further protect local waterways from nutrient runoff, Maryland does not allow farmers to spread manure or food processing residuals (FPRs) in winter. Learn about winter manure spreading restrictions. 

Learn about permit requirements for food processing residuals.

Requirements for farmers

Farmers are required to:

• Submit copies of their initial nutrient management plans to the Nutrient Management Program
• Update plans before they expire
• Take new soil samples a minimum of once every three years
• Obtain manure analyses (if using manure) at least every other year
• Submit Annual Implementation Reports documenting how they implemented their plans during the previous year. These reports are due to the department by March 1

Farmers who apply nutrients to 10 or more acres a year are required to attend a two-hour nutrient applicator course once every three years. Farmers who are certified to prepare their own nutrient management plans are exempt from this requirement. Check out upcoming voucher Training and Farmer Certification classes.
