BOOM KIT CALIBRATION
Below are some guidelines to help you calibrate your boom sprayer. This is a very
important step in operating your boom sprayer so that you don’t apply too much or too
little chemical.
1.
Use the suggested application rate (i.e. gallons per acre, 1000 sq.ft., or 100 sq.ft.)
2.
Using
Table 1,
find an application rate that corresponds to your chemical
manufacturers suggested application rate, and pressure at which your sprayer is
operating.
3.
Follow this application rate up the chart to find the speed at which to drive your ATV.

5.
The coverage area can be found by dividing tank size by the application rate.
Example:
15 gallons divided by 30 gallons/acre = 1/2 acre of coverage per tank.
