Fertilizer – Rate Adjustment

1. The dry fertilizer rate is adjusted by changing

sprocket ratios for each section. See Figure 4-18 for

desired settings. For best results use clean dry

fertilizer, free of clumps, or foreign material.

IMPORTANT

The operator must verify actual fertilizer output

before planting.

2. The fertilizer chart is based upon average size dry

fertilizer with a density of 65 lbs per cubic foot. If

using a fertilizer with a different density, apply the

following conversion factors, and use the closest rate

for application (See Table 4-1.)

Example: using a dry fertilizer with a density of 70 lbs/ft

and a desired application rate of 50 lbs/acre.

50 x .93 = 46.5 (use a setting from the rate chart nearest 46.5 lbs/acre)
