Apply the correct amount of fertilizer to your lawn by working from the nitrogen number on the bag instead of guessing. Enter your lawn area in square feet, the target nitrogen rate in pounds per thousand square feet, and the first number of the fertilizer analysis, which is the nitrogen percentage. A common target is one pound of nitrogen per thousand square feet per feeding, and most turf products list an analysis like twenty four zero six where twenty four is the nitrogen percent. The calculator divides the target nitrogen by that percentage to find how many pounds of product to spread across your whole lawn, so you neither burn the grass nor underfeed it. It also shows the total nitrogen applied. Everything is computed instantly in your browser without sending your lawn details anywhere.

The first number in the N-P-K label is the nitrogen percentage. A higher N number means less product delivers the same nitrogen.
A frequent target is about 1 pound of nitrogen per 1000 square feet per application, though this depends on your grass and season.
