Irrigation in the Pacific Northwest

Application Quantity Per Sprinkler Setting

The application quantity calculators determine the total amount of chemical to apply per set for hand-line, wheel-line, and solid set sprinklers. The fertilizer application calculator uses a concentration rate specified in lbs/acre and the herbicide application calculator uses a lower concentration rate units, such as pints/acre. The herbicide application calculator can also be used for pesticides and other applications with a similar concentration rate.
