Setting Fertilizer Rate
This page is an overview. For details on fertilizer rate set-
ting, refer to the Seed Rate Manual, 401-263B.
Agricultural Chemical Hazard:
Some chemicals cause serious burns, lung damage, and death.
Avoid contact with skin or eyes. Wear proper protective equip-
ment as required by chemical manufacturer. Avoid breathing of
chemical fumes. Wear respirator as required by chemical man-
ufacturer. Seek medical assistance immediately if accident
occurs. 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 fertil-
izer 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. Soil 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 remove pump drive chain when not in use.
Do not operate planter pump when not applying
material.
