TURFGRASS FERTILIZATION FOR NEW SOD
2018
Perennial turfgrasses, like all plants, obtain their mineral nutrients from the surrounding environment including the soil, air, and water. There are many essential nutrients required for growth and depending upon desired turfgrass use and soil nutrient status, newly planted sod may benefit from supplemental fertilization. This guide contains helpful tips to make sure your newly laid sod remains healthy and ready to enjoy!
. To calculate how much fertilizer to apply based on this range, simply follow these steps:
1) Measure the area of the turfgrass in square feet (Area)
2) Select the rate at which you are applying the nutrient in the fertilizer (Application Rate)
3) Determine the analysis of the fertilizer (Analysis)
Multiply these three values together as done below to determine how much fertilizer to apply.
Example: A homeowner wants to apply 1.0 lb of nitrogen per 1,000 ft2
to a 5,500 ft2 Rate
analysis of 16-4-8 based on a recent soil test. Area
Analysis 5,500 ft2 0.16 lbs of N Total Amount
x 1 lb of N x 1 lb of 16-4-8 = 34 lbs of 16-4-8 1,000 ft2
Many fertilizer products will also state on their label how many square feet they will cover. This eliminates the need for calculation, but still requires that the area be accurately measured. For example, “This bag covers 5,000 ft2
” means
the fertilizer manufacturer has determined how much area this bag will cover by using math similar to that shown above.
Fertilizers are most commonly applied using a rotary or drop spreader. Rotary spreaders cover a larger area and are less prone to error while drop spreaders are great for small areas and areas adjacent to sidewalks, driveways, or other hardscapes. In order to improve the uniformity of coverage using either type, it is often recommended to apply half of the fertilizer in one direction and the other half perpendicular to that direction.

FERTILIZER MATH & APPLICATION Once you select an appropriate fertilizer, it is important to accurately determine the application rate. Fertilizer nutrients are typically applied at rates of 0.5 to 1.0 lb of nutrient per 1,000 ft2
