7.11 Settings for unlisted fertiliser types
The settings for fertiliser types not listed in the fertiliser chart can be calculated
using the practice test kit (optional equipment).
To check the spreading unit settings quickly, we recommend the layout for one
passages.
To determine the spreading unit settings accurately, we recommend the layout
for three passages.
7.11.1 Requirements and conditions
Conduct the test on a dry day, with no wind, so the weather will not influence
the result.
We recommend a testing area that is horizontal in both directions. The tracks
must not have any significant cavities or heights since this may distort the
spreading pattern.
Carry out the test either on freshly mown grass or on a field with low vegeta-
tion (max. 10 cm).
Figure 7.22: Layout of the collecting vessels
Make sure that the collecting vessels are placed on level ground. Collecting
vessels set at an angle can cause measuring errors (see image above).
Running the calibration test (see 8.10: Calibration, page 91).
Adjust and lock the metering slides on the right and left-hand side (see 8.4:
Adjusting the application rate, page 79).
NOTICE
For calculating the settings for unlisted fertiliser types, please also see the sup-
plementary manual for the practice test kit.
NOTICE
The requirements and conditions apply to both one passage and three passag-
es.
Observe these conditions to ensure that the results are as accurate as possible.
