Fertilizer Calculator calculator can be used to determine the amount of fertilizer needed for a given area based on the recommended application rate.
Learn how to use the Fertilizer Calculator calculator and its working principles
If you have a lawn that is 2000 square feet and the recommended application rate is 5 lbs per 100 square feet, you would enter 2000 for the area and 5 for the application rate. The calculator would then tell you that you need 100 lbs of fertilizer.
The calculator works by multiplying the area by the application rate and then dividing by 100 to get the total amount of fertilizer needed.
