For some application rates and forward speeds, the output volume is already shown in the fertilizer
chart.
If you do not find your values in the fertilizer charts, they can be determined using the calibration
test calculator or from a formula.
Calculation with the calibration test calculator
u
Move the tab to set 300 kg/ha under 18 m.
u
The value of the nominal output volume for both outlets can now be read off above the value of
the forward speed of 8 km/h.
The nominal output volume per minute amounts to 72 kg/min.
If calibration is only to be carried out at one outlet, the total value of the nominal output volume is to be
halved.
u
Divide the read off value by 2 (= number of outlets).
The nominal output volume per output amounts to 36 kg/min.

Calculation with formula
Nominal output
volume (kg/min)
=
Forward speed (km/h) x Working width (m) x Application rate (kg/ha)
Time over 100 m
Calculation for example
8 km/h x 18 m x 300 kg/ha
= 72 kg/min
