Auxiliary calculation for fertilizer distribution
Adjustments and operations
In order to distribute other amounts of fertilizer with spacing and areas which are
different from those presented in the tables, we suggest a quick calculation, in which all
data used may be replaced by data of your own interest simply using the formula below,
which contains the following elements:
A
= area to be fertilized (m²).
B
= spacing between rows of the crop (m).
C
= amount of fertilizer to be distributed in the area (Kg).
D
= distance to cover for the drop test (m).
X
= the amount of grams that should be dropped on "d"?
Formula:
B x C x D
A
X =
Example:
A =
10.000 m
2
B =
0,90 m
C =
250 kg
D =
50 m
X =
?
0,90 x 250 x 50
10.000
X =
1.125 kg or
X = 1.125 grams in 50 meters in each row.
Then adjust the planter to a setting to distribute the amount you calculated, or a setting
which is closest to the desired one; in the predetermined distance for the test.
X =
