Calibration of Spray Equipment

-Stephen Komar and Bill Bamka

We have been getting calls related to proper spray calibration.

A simple way to perform a calibration is the 1/128th method. This method is based on spraying 1/128th of an acre per nozzle and simply collecting the spray released during the time it takes to travel over that area. Since there are 128 fluid ounces in 1 gallon, the number of ounces collected equals the application rate in gallons per acre. This method works well for broadcast applications, banded applications and directed applications. The 1/128th method is described in NJAES Fact Sheet 1085, Sprayer Calibration.

Proper calibration can ensure the best possible control and can save you $.
