How do I apply 1 pound of nitrogen per 1,000 square feet?
Divide 1 by the first bag number as a decimal. A bag with 25% nitrogen needs 1 ÷ 0.25 = 4 pounds of product per 1,000 square feet.
How many bags of fertilizer do I need?
Bags = total pounds of product ÷ bag weight, rounded up to a whole bag. Enter the bag weight to see it.
What do the numbers on a fertilizer bag mean?

What does this not include?
Price, which rate your grass or soil needs, timing, spreader settings, and local rules on phosphorus or fertilizer use. Check the bag and your local guidance.
