Liquid Fertilizer Rates
Dry Fertilizer Attachment
NOTE: Fertilizer application rates can vary from the
weights in the charts. Make field checks to assure
you are applying fertilizer at the desired rate.
Use the following instructions to check the exact number
of pounds your fertilizer attachment will actually deliver on
a 30 inch row spacing.
1. Remove a hose from one of the fertilizer hoppers and
attach a container under the opening.
2. Engage the fertilizer attachment and drive forward for
174 feet.
3. Weigh the amount of fertilizer caught in the container
and multiply that amount by 100. The result will be the
pounds of fertilizer delivered per acre when planting in
30 inch rows.
To assure proper application check the gauge tires and
contact drive tire for proper inflation, see Tire Inflation
Chart in “Section 10 Appendix” on page
62.
NOTE: Before applying fertilizer make sure that au-
gers are rotating correctly and are positioned for your
desired rate setting, see Figure 5-4 & Figure 5-5.
The following application charts were calculated with a
bulk density of 65 pounds per cubic foot.
