Activities before spreading
132
A tray test checks the fertiliser distribution as the spreader distributes
it. The results of this test will indicate if you can improve the settings
of the spreader, thereby improving the distribution of fertiliser and
limiting loss.
You can have a tray test performed by specialised companies, but you
can also do the test on your own. You will have to purchase some
materials for it, however.
We recommend that you have a specialist company perform the tray
test. as they can also provide you with advice and answer your
questions.
When to perform the tray test:
•
When using fertiliser types not indicated in the spreading chart
book.
•
When using fertiliser types with varying distribution and density
from the values indicated in the spreading chart book.
•
When using fertiliser of moderate quality.
•
Test should be carried out annually on the left and the right side to
check the equal distribution of both spreading discs.
•
After each change to the spreading mechanism of the spreader or
when parts are replaced.

NDICATION
Weather conditions have a great influence on the spreading pattern
while spreading, as well as while performing the tray test. The tray test
should be performed with dry weather, low humidity and with a
maximum wind speed of 3 m/s (wind force of 2).
