7.8 Calibration test
For precise control of the spreading quantity we recommend running a new cali-
bration test every time you change spreading material types.
Carry out a calibration test:

Before spreading for the first time.

If the quality of the spreading material changes significantly (e.g. dampness)

If you are using a new spreading material.
The calibration test can be carried out in a stationary position with the PTO run-
ning.
7.8.1 Calculating the nominal spreading quantity
Calculate the nominal spreading quantity before starting the calibration test.
To calculate the nominal spreading quantity per minute you will require:

The ground speed,

the working width,

the desired application rate.
Example : you would like to determine the nominal spreading quantity. The
ground speed is 3 km/h , the working width is set to 4 m and the application rate
should be 50 g/m
2
.
If you cannot find the values in the fertiliser chart, you must determine the nominal
spreading quantity using a formula.
Nominal spreading
quantity
(kg/min) = Ground speed (km/h) x working width (m) x application rate (g/m

)

Example: 3 km/h x 4 m x 50 g/m

= 10 kg/min
