Field Evaluation of Container Nursery Irrigation Systems: Uniformity of Water Application of Sprinkler Systems: FS98-2/AE194, 6/2001

Abstract

Why should I be concerned with the uniformity of my irrigation system? Why is it important to maintain high uniformity? This is important because high uniformity signifies that all the plants in the irrigated zone will receive almost the same amount of water in a given time. For sprinkler irrigation, it means that the depth of water application throughout the entire irrigated area is about the same. Consequently, uniform water application is necessary to maximize the efficiency of water use in the nursery and save water. There is a simple method to evaluate the uniformity of irrigation and the test should be performed at least once a year. The uniformity may change with time, and often simple repairs or changes can improve system performance.
