5.6.7.4. 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.

Note.
The
average collected value calculation must be repeated for every fertilizer spreading test.

Depending on the resulting distribution graph, you may need to adjust the fertilizer spreader to achieve op-timal distribution over the
field (graph G).
Warning.
When performing adjustments to optimize the spreading graphs, it is best to perform just one ad-justment at a time so as
to understand how the machine reacts to each single alteration and hence learn how to adjust the fertilizer spreader. (for instance, do
not move the short blades and long blades at the same time as this may be confusing).
