Weather Ready Farms: Irrigation Water Management

March 21, 2018
Climate variability, including extended periods of dry conditions and sometimes drought, are common on the Great Plains. When managing under these extreme conditions, irrigators need to understand daily and seasonal crop water use patterns and adopt practices and technology that result in more bushels of grain per inch of water applied.

Distribution of the 1-square-kilometer cells where irrigated land in 2012 exceeded 50 percent of the cell area (blue-green dots) in Nebraska. Pink corresponds to declining annual, while yellow corresponds to declining irrigation-season (May-July) precipitation rates over the 1979-2015 period. The brownish color marks their spatial overlap.

Research Shows Large-Scale Irrigation Reduces Local Precipitation

February 28, 2018
A University of Nebraska-Lincoln researcher has shown that widespread irrigation has resulted in a net moisture loss in Nebraska, a finding that could have worldwide water conservation implications if substantiated by further research.
