These must be known:
1.
Tree spacing in feet (swath width)
2.
Tractor speed in feet per minute
3.
Gallons per acre desired
Note
:
(a.)
1 acre = 43,560 sq. ft.
(b.)
1 MPH = 88 ft./min.
Tree spacing _____ ft. x tractor speed _____ ft./min. x application rate _____ gal./acre
÷
43,560 =
G.P.M. Divide G.P.M. by number of sprayer nozzles to determine G.P.M. per nozzle. Now choose
correct nozzle disc and pressure setting from charts. Charts give G.P.M. per nozzle disc.
CALIBRATION FORM
Tree spacing ______________________________ ft.
Tractor speed _____________________________ ft./min.
Application rate ___________________________ gal./acre
Tree spacing _____ ft. x tractor speed _____ ft./min. x application rate _____ gal./acre
÷
43,560 =
G.P.M.
Next: G.P.M. _____
÷
number of nozzles _____ = _____ G.P.M. per nozzle
Refer to chart for: Nozzle disc # __________ Swirl plate __________
Pressure setting __________ P.S.I.
