It is important that the sprayer operator know exactly how many gallons of spray solution are being applied to the acre. A procedure for calibrating a weed sprayer is outlined in Experiment Station Circular No. 69. Since the speed of the tractor may vary between fields, it is necessary to re-check the output of the sprayer for each field. A simple method of field checking the sprayer is presented in this pamphlet.
