Fertilizer Density Adjustment
The fertilizer meter rate charts are based on fertilizer with
a density of 1.04 kilograms per liter.
If you are applying fertilizer of a different density, use the
following table to convert application rate.
Multiply the desired application rate by the conversion
factor.
Use the “Chart Rate” to determine the initial sprocket
settings.
If the rate measured in calibration varies from the desired
field rate by more than a few percent, apply the error
percentage to the Chart Rate, and pick a new sprocket
pairing based on that.
Dry Fertilizer Rate Check
Use the following instructions to check the exact number
of kilograms your fertilizer attachment delivers.
1. Adjust for your fertilizer density (above).
2. Consult the Fertilizer Rate charts (pages 36-37).
3. Install the Driving and Driven sprockets called out in
the chart (page 33).
4. Remove a hose from one of the fertilizer hoppers
and attach a container under the opening.
5. Engage the fertilizer attachment and drive forward
for the “Distance for 1/100th ha”.
6. Weigh the amount of fertilizer caught in the container
and multiply that amount by 100. The result is the
kilograms of fertilizer delivered per hectare.
Density kg/l 0.72 0.80 0.88 0.96 1.04 1.12 0.87 0.81
Correction Factor 1.45 1.30 1.20 1.10 1.00 0.93 0.87 0.81
You want to apply at: 125 kg/ha.
The fertilizer density is: 0.96 kg/l
This is a correction factor of: 1.10
125 x 1.10 = 137.5
Use chart rate closest to 137.5 kilograms per hectare.
