Calculation formula and reply to question 2:
Available spray mixture [l] – residual amount [l]
required rate of water [l/ha]
=
area to be sprayed [ha]
1000 [l] (Nominal tank volume) – 20 [l] (residual amount)
500 [l/ha] required rate of water
=
1.96 [ha]
6.4.1.2 Filling table for finishing off remaining field areas
Important!
For determining the required refilling amount for the last spray
agent tank filling use the "Filling table for residual areas". De-
duct the surplus amount in the spray line from the calculated
refilling quantity. For this see chapter "Spray lines", page 133.
Hint!
The indicated refilling quantities are valid for an application rate
of 100 l/ha. For all other spray rates the refilling quantity has to
be increased by a multiple.

Example:
Remaining left over distance: 100 m
Spray rate: 100 l/ha
Sprayer booms: Q-plus-boom
Working width: 15 m
Number of boom part section feed controls: 5
Residual amount spray line: 5.2 l
1. Determine the refilling quantity with the aid of the filling table. For
this example, the refilling quantity is 15 l.
2. Deduct the residual amount in the spray line from the calculated
refilling quantity.
Necessary refilling quantity: 15 l – 5.2 l = 9.8 l
