How do y’all measure the pounds per sq ft? You actually put it on a scale?

Lawn fertilizer, correct? Often I’ll use a scale, but for a typical granular lawn fertilizer 1 pound is equivalent to 2 cups - you can check that on a kitchen scale - so if you need to apply 10 pounds of fertilizer, 20 cups will get you close, so you can measure it by volume if you want using the 2 cups=1 pound rule.

Remember it is pounds of nitrogen applied per 1,000 sq ft, not per 1 sq ft.

Let me provide a simpler way than TF99 to calculate application rate.

For 1 pound of N per 1000 sq ft per application (e.g. for St Augustine or Bermudagrass) divide the % N on the fertilizer bag into 100. For example, using a 24-2-11, 100 divided by 24 = 4 pounds (rounded off) of that fertilizer applied per 1000 sq ft of lawn.

For 1/2 pound of N per 1000 sq ft per application (e.g., Centipede or Zoysia) divide the % N on the fertilizer bag into 50. For example, using a 15-0-15 granular fertilizer, 50 divided by 15 = 3 1/3 pounds of fertilizer applied per 1000 sq ft of lawn.
