8. 6 Using the spreading calibration chart
8.6.1 Information on the calibration chart
The values in the calibration chart have been determined using the solid fertiliser
broadcaster testing rig.
The fertilisers used have been procured from fertiliser manufacturers or from stor-
age depots. Experience shows that your spreading materials - even with identical
specifications - may have different spreading properties because of storage,
transport and many other reasons.
This means that application of the settings for the solid fertiliser broadcaster given
in the calibration chart could result in a different spreading volume or poor distri-
bution of spreading material.
Therefore observe the following instructions:

Always check the actual spreading material volume by performing a calibra-
tion test (see chapter B.6 for each model of the solid fertiliser broadcaster).

Check the working width of the fertiliser distribution with a practice test kit (op-
tion).

Use only fertilisers listed in the spreading calibration charts.

Please contact us if you do not find a particular fertiliser type mentioned in the
calibration charts.

Follow the settings exactly. Even a slightly incorrect setting may adversely af-
fect the spreading pattern.
When using urea note particularly the following:

Because of fertiliser imports, urea is available in widely varying qualities and
particle sizes. This may make different spreader settings necessary.

Urea is more sensitive to wind and absorbs more moisture than other fertilis-
ers.
8.6.2 Settings as per calibration chart
The operator determines the hopper mounting height, fertiliser drop point, meter-
ing slide adjustment, spreading disc type and PTO speed for optimum spreading
from the
calibration chart depending on fertiliser type, working width, application
rate, ground speed and fertilisation method.
NOTICE
The operator is responsible for making the correct settings according to the fer-
tiliser in use.
We point out specifically that we do not accept any liability for damage resulting
from incorrect spreader settings.
