Liquid Applications
Boom Cal
For liquid sprayers, the boom cal value is the width of the individual boom sections. Calculate the width of each
boom section by measuring the spacing between spray tips in inches [cm] and then multiplying by the number
of tips in each boom section.
Band Spraying Adjustment
Calculate the Adjusted Applied Rate with the following formula:
where GPA = Gallons per Acre, BW = the Band Width in inches [cm] depending upon how the boom cal was
calculated), and TS = tip spacing.
For Example:
Broadcast Rate = 20 Gallons per Acre [200 L/ha], Spacing = 40 inches [100 cm], and Band Width = 14
inches [40 cm]
the Adjusted Applied Rate is 7 Gallons per Acre or 80 liters per hectare.
Meter Cal
The flow meter calibration number can be found on the tag attached to each flow meter. Copy the information
from the tag for future reference as the tags may fade or be lost during equipment operation.
