Sprayer Calibration

Sprayer Calibration is the process of determining the amount
of spray solution to be applied to a given area and ensuring
the target or application rate is being applied according to its
product label.
The application rate of a sprayer operating manually remains
constant as long as ground speed, spray pressure, number of
nozzles and nozzle orifices remain unchanged. If there is any
change in these factors, the application rate will change.
The automatic spray controller, however, maintains a constant
application rate while allowing for some variation in ground
speed and boom width.
To achieve a constant application rate, the spraying system
must be correctly maintained and calibrated
Nozzle spray patterns & outputs must be checked regularly to ensure correct &
uniform application rates because nozzles wear with use.

Calibration Procedure

Five steps are required to complete calibration:
1 Application Rate Required - Calculating & clearly
understanding the volume of liquid (chemical & water)
required for the specific application over a given area.
2 Nozzle Output Required - Calculating the output required
for the application.
3 Nozzle Selection - Selecting and fitting the appropriate
nozzles.
4 Controller Set-Up - Checking controller set-up values and
entering values for the nozzles & spray rates required.
5 Test Actual Sprayer Output - Test the actual output to
ensure the accuracy of the nozzle application rate before
spraying.
Uneven volumes from individual nozzles will result in variations in the application
rate across the width of the boom. Spray efficiency will be reduced. Crop damage
may result.
If you have any further questions, Goldacres recommends that you contact your
nozzle supplier or your Goldacres dealer for additional information.
Application rates & droplet size for a situation can be sourced from chemical &
nozzle manufacturers and the local agronomist.

1 Application Rate Required

The application rate is entirely dependant on the chemical
manufacturer's application specifications and conditions of the
target at the time of application.
Refer to the manufacturer's information and/or consult with the
local agronomist for the best application rates and droplet size
for your situation.
All nozzles have a pressure and flow rate range to acheive the best results.
Ensure you have selected the nozzle which best suit the application to avoid any
problems.
