What is a typical maintenance nitrogen rate for warm-season turfgrass in Florida, expressed as pounds of actual nitrogen per 1,000 square feet per year?

What is a typical maintenance nitrogen rate for warm-season turfgrass in Florida, expressed as pounds of actual nitrogen per 1,000 square feet per year?

• A. 0.5 to 1.0
• B. 1.5 to 2.5
• C. 3 to 4
• D. 5 to 6

Answer: (B)

In warm-season turfgrass grown in Florida, the aim is to keep color and density while avoiding excessive growth that leads to more mowing and potential nutrient loss. The typical maintenance rate is about 1.5 to 2.5 pounds of actual nitrogen per 1,000 square feet per year. This range supports healthy turf through the growing season when warm-season grasses actively grow, and it’s usually split into multiple smaller applications rather than one big dose. Rates below this can leave turf looking pale or thin, while rates above this can cause rapid growth, higher mowing demands, and a greater risk of leaching in Florida’s sandy, rain-prone soils.
