Step 1
Check the Sprayer is in Good Working Order
Step 2
Determine Actual Speed of Travel
Measure and mark a straight path of 100 metres
(or more) of travelling conditions similar to the
orchard or vine yard you are going to spray.
Half fill the spray tank & record the time (in
seconds) to travel the measured distance.
Make sure that the tractor is travelling at spraying
speed when you pass the start and finish marks and
ensure the fan and pump are at operational speed.
If you have a hectare metre or automatic controller
you need to check the speed calibration of the
controller.

Step 3
Determine Spraying Volume Required
It is essential to determine the liquid volume per
hectare required to effectively spray a crop without
overspraying or underspraying.
Use your own experience or a registered rate
calibration consultant to determine effective
volume in litres per hectare.

used:
Step 5
Determine ideal spray pressure (bar)
Step 6A, B, C
Determine & Select Nozzles
Determine nozzle flow rate required:
Litres/Minute
=
Litres/Ha x Km/hr ÷ 600 ÷ Total Number
of Nozzles Used x Row Spacing (m)
x Number of Rows in One Pass
x ÷ 600 ÷ x
= litres/minute/for all nozzles
(divide by 2 for each half)

Step 7
Fit & Test Selected Nozzles
The most important calibration is to test for actual
litre per hectare.
Fill your spray tank to overflowing and run the
sprayer for one minute, at the above operating
settings, and record the total litres per minute used.
Output/min/side (l/min)
=
Output (litres) ÷ Time (minutes)
÷
= litres/minute
Step 8
Calculate the Actual Application Rate
To calculate actual application rate (litres per
hectare), use the following formula:
Application Rate (l/ha)
=
Total Sprayer Output (l/min) x 600
÷ Speed (Km/hr) ÷ Row Spacing (m)
÷ Number Rows in One Pass
x 600 ÷ ÷ ÷
= litres/ha
