Lawn Feeding Tools & Calculators
Free, instant, no sign-up. Turf feeding fails at a unit boundary, not an information boundary — recommendations come in pounds of nitrogen, bags come as a percentage analysis, and spreaders meter in unlabelled dial numbers. These are the solvers that close the gaps.
Fertilizer Rate Calculator
Bag analysis and lawn area in, pounds on the ground out — plus bags to buy, nitrogen delivered and the cost per pound of N.

Two 4-inch soil readings in, a feeding window and a date out — because timing turfgrass by calendar month is wrong across most of the country.
