Fertilizer Rate
On fertilizer drills, the fertilizer-application rate is directly
related to ground speed. To adjust the application rate,
turn adjustment knob on back of fertilizer tray. See Figure
3-1. This controls the size of the fertilizer outlet. For fertil-
izer rates, refer to the chart below.
The application rates for dry, granular fertilizer depend on
many factors, including fertilizer type, fertilizer density, rel-
ative humidity and moisture content of the material.
Fertilizer Rate Chart
Density Conversion Chart
The fertilizer rate chart is based on fertilizer with a density
of 65 pounds per cubic foot. If you are applying fertilizer of
a different density, use the following table to convert your
application rate.

Small Seeds Attachment
To set and calibrate the seeding rate on the optional small-
seeds attachment, follow these steps.
1.
Set seed-rate handle on small-seeds attachment as
indicated by the Small Seeds Rate Chart, page 24.
2.
Calibrate small-seeds attachment to your material by
following steps under Checking the Seeding Rate,
page 15.
Example: Your fertilizer has a density of 75 pounds per
cubic foot, and you want to apply 100 pounds per acre.
Multiply desired application rate by the conversion fac-
tor.
100 x 0.87 = 87
Adjust drill to setting closest to 87 pounds per acre.
