Perform the following steps to ensure that
the liquid fertilizer pump is calibrated
properly:
1 1. Set the pointer, 1 FIG. 18, 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 (final)
Area (final) - Area (initial)
= Application Rate: gal/ac (L/ha)
5. Adjust, if necessary, the pump
setting and repeat the above
procedure to confirm application rate.
