Fertilizer Rate Chart

Density Conversion Chart
The fertilizer meter rate charts are based on fertilizer with a density of 65 pounds per cubic foot (1.04 kilograms per liter).
If you are applying fertilizer of a different density, use the following table to convert application rate.
Example: Your fertilizer has a density of 75 pounds per cubic foot, and you want to apply 100 pounds per acre. Multiply
the desired application rate by the conversion factor.
100 x 0.87 = 87
Adjust drill to the setting closest to 87 pounds per acre.
