Auxiliary calculation for seeds and fertilizer distribution
In order to distribute other amounts of seed and fertilizer using spacing and areas
which are different from those depicted in the tables, we suggest a quick calculation, where
all used data can be replaced by data of your own interest using the formula below, which
contains the following elements:
A
= area to be seeded or fertilized (m²).
B
= spacing between rows of the crop (mm).
C
= amount of fertilizer to be distributed in the area (kg).
D
= distance to cover for the test (m).
X
= amount of grams that should be dropped on "D" ?
Formula:
X = B x C x D
A
Example:
A
= 10,000 m²
B
= 316 mm
X
= 316 x 350 x 50
10,000
C
= 350 kg
X
= 553 grams in 50 meters per row unit.
D
= 50 m
X
= ?
Then, adjust the equipment to distribute the found amount or to one that is closest to
the desired amount, in the predetermined distance for the test.
