PUMP
Perform the following steps to ensure that the liquid fertilizer pump is calibrated
properly:
1. Set the pointer, 1 Figure 39, on the
metering pump to a setting that
corresponds to the desired liquid
application rate.
2. Before seeding, accurately measure or
carefully estimate the amount of liquid in
the liquid fertilizer tank and note the
beginning area reading on the monitor
display.
3. Seed a significantly large area. Stop and
again measure or estimate the amount
of liquid remaining in the tank and note
the area covered.
4. Use the following formula to calculate the application rate:
Tank Level (initial) − Tank Level (�inal)
Area (�inal) − Area (initial)
= Application Rate gal ac ⁄ (L ha) ⁄
5. Adjust, if necessary, the pump setting and repeat the above procedure to confirm
application rate.
