4. Switch on the agitator.
5. Add the calculated preparation quantity.
6. Top up the water shortfall.
7. Before starting the spraying operation stir up
the spraying mixture as instructed by the crop
protection agent manufacturer.
Calculating filling / refill
quantities
NOTE
Use the “Filling table for residual areas” (chapter
8.2.2) to calculate the required refilling quantity for
the last spraying mixture container filling.
Example 1: Filling quantities
The following is known:
Rated tank volume 1000 l
Residual quantity in tank 0 l
Required water 400 l/ha
Required amount of chemical per ha
Product A 1.5 kg
Product B 1.0 l
Question:
How many l of water, how many kg or product
A and how many l of product B do you have to
fill in, if the area to be treated is 2.5 ha?
Calculation formula and solution
Component [quantity/ha] x area [ha]
= required quantity [l] or [kg]
Water: 400 l/ha x 2.5 ha = 1000 l
Product A: 1.5 kg/ha x 2.5 ha = 3.75 kg
Product B: 1.0 l/ha x 2.5 ha = 2.5 l
Example 2: Addition of product, area
The following is known:
Rated tank volume 1000 l
Residual quantity in tank 200 l
Required water 500 l/ha
Recommended concentration 0.15 % l/l or kg/l
Question 1:
How many l or kg preparation must be metered
for one container filling?
Calculation formula and answer to
question 1:
Water refill quantity [l] x concentration [%]
100
= product addition [l] or [kg]
(1000-200) [l] x 0.15 [%]
100
= 1.2 [l] or [kg]
Question 2:
What is the area in hectares that can be treated
with one tank filling, if the tank can be sprayed
empty to a residual quantity of 20 l?
Calculation formula and answer to
question 2:
Available amount of chemical [l] – Residual
quantity [l]
Required water [l/ha]
= area [ha]
1000 [l] (rated volume) – 20 [l] (residual quantity)
500 [l/ha] (required water)
= 1.96 [ha]
