Density Conversion Charts
The fertilizer meter rate charts are based on fertilizer
with a density of 65 pounds per cubic foot. If you are
applying fertilizer of a different density, use the follow-
ing 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.
