Great Plains recommends checking with your local
agronomist as soil conditions vary. Soil conditions in your
area may need less or more fertilizer than represented in
these charts. In furrow, do not exceed 12 gallons per
acre in any case.
The liquid fertilizer system is designed to operate (ide-
ally) between 15 and 40 psi, but in no case more than 65
psi. Several system elements affect system pressure,
and need initial setup, periodic maintenance, and adjust-
ment when changing fertilizer rates.
