Cutting irrigation waste by measuring leaves
April 17, 2009

A branch of the USDA is working on a system to measure leaf temperature as a way to determine which parts of fields require irrigation and which parts don't need it. Irrigation consumes more water in Nebraska than all other categories of use combined, so its efficient use is especially important to the Cornhusker state. Irrigation takes many forms, including center-pivot, drip, and canal. While canal irrigation has generally been eclipsed by other types in Nebraska, some systems still use it and require canal gates to manage the water distribution.
