Setting Fertilizer Rate
This page is an overview. For details on fertilizer rate
setting, refer to the Seed Rate Manual, 401-625B.
Possible Chemical Hazard:
Wear proper protective equipment as required by chemical
manufacturer. Avoid breathing of chemical fumes. Wear
respirator as required by chemical manufacturer. Seek medical
assistance immediately if accident occurs. Some chemicals
cause serious burns, lung damage, and death. Avoid contact
with skin or eyes. Know what to do in case of an accident.
Fertilizer rate is controlled by pump rate (for the Great
Plains ground drive pump). Consistent delivery across
the planter is controlled by orifice size at row unit
drop-line points.
Consistent system operation also requires a correctly
adjust relief valve and a well-maintained strainer ahead
of the pump. See “Important Safety Information” on
page 1 and “Important Safety Information” on page 1.
Piston Pump
The liquid fertilizer option uses a piston pump. For pump
operation and pump maintenance refer to the pump
manual, supplied in the liquid fertilizer option package.
The pump is driven by a ground contact wheel , and
fertilizer rate is independent of seed rate. Coarse
fertilizer rate is set by a sprocket
on the ground drive
assembly. Fine rate is set by a dial on the pump. For
settings, see the Seed Rate manual.
Note: Great Plains recommends checking with your local
Agronomist, as soil conditions vary. Conditions in
your area may need lesser or more amounts of
fertilizer than represented in these charts. Do not
exceed 12 gallons per acre (112 liters/ha) in any
case.
Note: Always disable the pump drive when not in use.
Use ground contact wheel lock up if installed. On
older models remove the chain. Do not operate
planter pump when not applying material.
