How much fertilizer does it take per acre?

(2) Amount of product needed to apply 43.5 pounds of nitrogen per acre. To determine the amount of product needed to deliver 1 pound of nitrogen per thousand square feet, divide 100 by the first number in the fertilizer ratio. For example, for 16-4-8 fertilizer, divide 100 by 16.

How many square feet does a 50 pound bag of fertilizer cover?

Now that you know 3.8 lb of 26-5-10 fertilizer will cover 1000 sq ft, determine how many times 3.8 lb goes into 50 lb. 50 lb ÷ 3.8 lb = 13.2. Now multiply 13.2 by 1000 sq ft: 13.2 × 1000 sq ft = 13,200 sq ft. Thus, a 50-lb bag of 26-510 covers 13,200 sq ft at a rate of 1.0 lb nitrogen per 1000 sq ft.
