CALCULATING THE BOOM WIDTH
(CALIBRATION) FOR LIQUID APPLICATIONS
You can calculate boom calibration for two different types of spray applications,
Broadcast spraying and Band spraying.
Broadcast
Spraying
Calculate the boom width by mulitplying the number of tips in each boom section by
the space between each tip in the section. This will give you the width for each
boom section.
For example:
T = Number of tips
D = Space between the tips
W = Width of each boom
T x D = W
If
T = 20 and D = 40 inches
Then
W = 800 inches
20 x 40 inches = 800 inches
Band
Spraying
Calculate the adjusted applied rate by multiplying the broadcast rate by the band
width and dividing by the space between each tip in the boom.
For example:
D = Space between the tips
B = Width of the band
BR = Broadcast rate
AR = Adjusted rate
AR = BR x B
D
If
Broadcast rate = 20 GPA
Band width = 14
Spacing = 40
(20 x 14) / 40 = 7
Therefore, the adjusted applied rate is 7 GPA.
