Conducting a micro-irrigation system uniformity evaluation in your nursery

New MSU Extension factsheet outlines the steps for conducting a micro-irrigation system Distribution Uniformity check, as well as examples of calculations and results.

Editor’s note: The factsheet Conducting a Water Application Uniformity Evaluation for a Micro Irrigation System in the Nursery has been updated July 10, 2012. An error was discovered in the earlier version. Please destroy and disregard the earlier version and replace it with the current one in this article.

A new factsheet, Conducting a Water Application Uniformity Evaluation for a Micro Irrigation System in the Nursery, for nursery growers on how to conduct their own micro-irrigation uniformity check or Distribution Uniformity (DU) has been developed by MSU Extension. A DU is easy to test for and should be done twice a year.

The factsheet discusses the seven steps to conduct a DU check for micro-irrigation systems and provides two examples to aid in understanding the process. The authors also provide information on how to correct problems that may be causing an improper DU for a micro-irrigation system. 

Uniform water application in the nursery is essential to maximize water use efficiency and to conserve water by avoiding over applications.
