Liquid Fertilizer Rates

Liquid fertilizer planter models (1625AHL) use a

CDS-John Blue

piston pump. For pump operation and

pump maintenance refer to the Planter Operator manual

and CDS-John Blue

pump manual. The

CDS-John Blue

manual is supplied with the planter.

The pump is driven by a ground drive wheel, and

fertilizer rate is independent of seed rate. Fertilizer rate is

set by a pump dial and a sprocket on the ground drive

assembly.

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 112 liters/ha (12 gallons/acre) in any case.

Note: Always lock-up the ground drive when not in use.

Do not operate planter pump when not applying

material. See the planter Operator manual for lock-

up instructions.

Dial setting required for your rate. See page 96.
