What is the maximum single nitrogen application rate allowed in Maryland?

• A. 1.0 lb N / 1,000 sq ft.
• B. 0.5 lb N / 1,000 sq ft.
• C. 2.0 lb N / 1,000 sq ft.
• D. 3.0 lb N / 1,000 sq ft.

Answer: (A)

The amount you can apply in one go is limited to 1.0 pound of nitrogen per 1,000 square feet. This cap helps protect water quality by preventing large, rapid nitrogen inputs that can leach or run off, especially during rain events. In practice, you meet the turf’s overall nitrogen needs by spreading multiple smaller applications over the season rather than dumping a big dose at once. Always calculate based on the treated area, and consider soil conditions and weather. Rates higher than this single-application limit increase the risk of environmental harm and rule violations, while a lower rate would not meet typical turf needs without adjusting the plan.
