Calculation of seeds/meter for the different number of holes on the plates
•
Use the same method for every table to calculate the amount of seeds/meter,
being it mechanical or pneumatic.
NOTE
Calculation of seeds/meter according to the different number of holes in the
seed plates.
When using a seed plate that has a number of holes that is not included in the table, it
is possible to find the amount of seeds/meter it will distribute by doing the calculation below:
Example:
It is desired to use a seed plate with
20 holes
, on a
26 x 38
combination.
The tables from the previous pages do not have a seed plate with
20 holes
. The amount
of holes that is closer to that number is
24 holes
(mechanical) or
27 holes
(pneumatic). For
the
26 x 38
combination, the amount of seeds per meter is
2.23
(mechanical or pneumatic),
according to the table.
For the example, we are going to use the mechanical seed distribution table
(
05.03.03.2997
).
Data:
Amount of seeds per meter (table) =
2.23
.
Number of holes on the new seed plate:
20
(not in the table).
Number of holes on the mechanical seed distribution table to use as reference:
24
.
Multiply the amount of seeds per meter
(2.23)
by the number of holes on the new
desired seed plate
(20)
. Divide the value by the number of holes used as reference
(24)
.
Calculation:
2.23 x 20 = 44.6 =
1.86 seeds per linear meter.
24 24
Answer:
1.86
seeds per meter will be distributed using a plate with
20 holes
, on a 26 x 38
combination.
