USE AND MAINTENANCE
Distribution test. Layout of collection trays and passes to be made.
Collection tray. Shape and size of collection tray to be used during distribution test.
Estimation of the results and adjustments
The graphs below show the typical patterns that can be achieved during spreading tests.
In the graphs featured, the amount of fertilizer contained in the collection trays is given as a percentage. To
interpret the graphs correctly, you should bear in mind that the reference value, which is 100%, is given by
the amount of fertilizer collected in the individual containers when the fertilizer spreader is adjusted to pro-
duce even, uniform distribution (Optimal spreading).

Note. The term 40,000 is given by the number of trays measuring 50x50 cm that fit on a hectare of land.
The
reference value obtained above is a theoretical value. In reality however, the grains of fertilizer some-
times bounce and a part bounces out of the collection containers during spreading tests. For this reason,
even under ideal spreading conditions, the quantity of fertilizer that can be collected in every single con-
tainer will be lower than the theoretical reference value obtained above.
In order to plot the graph with greater precision, we recommend taking the
average collected value that is
obtained as the average value of the quantity of fertilizer collected in all the single containers as reference.
