FERTILIZER RATES - CENTRIFUGAL PUMP AND PISTON PUMP WITH MANIFOLDS
NOTE: Refer to the Fertilizer Rates table on the following page to size orifice for approximately 40 psi
pressure for even fertilizer distribution.
The following table can be used to determine which orifice plates can be used to achieve the desired gallons per acre
application rate for fertilizer. The GPA is calculated at 5 mph with a 30" width.
NOTE: Operating pressure while operating in the field should be 30 - 40 psi. Orifice diameter is factory
installed at 0.037".
