What is the maximum single nitrogen application rate for Maryland turf?

• A. 0.5 lbs N per 1,000 sq ft
• B. 0.7 lbs N per 1,000 sq ft
• C. 1.0 lb N per 1,000 sq ft
• D. 1.2 lbs N per 1,000 sq ft

Answer: (B)

Understanding how much nitrogen you can apply at once helps protect water quality and keep turf healthy. In Maryland, the limit for a single nitrogen application to turf is 0.7 pounds of nitrogen per 1,000 square feet. This cap prevents rapid, excessive growth that can lead to mowing stress, thatch buildup, and greater risk of nutrient runoff or leaching, especially during storms. If you need more nitrogen for the season, you split it into several smaller applications and stay within the overall recommended seasonal total for your turf type and conditions. The other amounts are either below the maximum (0.5 is fine but not the cap) or exceed it (1.0 and 1.2 would surpass the allowed per‑application limit).
