Auxiliary calculation for fertilizer distribution
Adjustments and operations
To distribute other amounts of fertilizer in different spacings and areas from those
presented in the tables we suggest a quick calculation, where all used data can be changed
to ones of your own interest. Use 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 travel for the distribution test (m).
X
= How many grams should be dropped in "D"?
Formula:
Example:
A
= 10,000 m²
B
= 0.90 m
C
= 250 kg
D
= 50 m
X
= ?
X = 1.125 kg or
X = 1,125 grams on 50 meters for each row unit.
Adjust the equipment to distribute the found amount or the best approximation in the
delimited space for the test.
The amount of "grams on 50 meters for each row unit" appears on the column of
several tables of this manual.
