Field Evaluation of Container Nursery Irrigation Systems: Part 2: Measuring Application Rates

Abstract

Performance of sprinkler and microirrigation systems can be evaluated by measuring operating pressures, application rates, and uniformity of water application under nursery conditions. We discuss the measurement of application rates for overhead sprinkler systems. The application rate is defined as the average depth of water applied per unit time of system operation. For a sprinkler system, application rate is usually expressed in inches per hour.
