In-canopy center pivot sprinkler head entangled in the corn canopy

In-Canopy vs. Above-Canopy Sprinklers: Consider Pros and Cons

April 5, 2018
Center pivot sprinkler packages placed in the canopy have some potential to increase the application efficiency of center pivot and lateral move irrigation systems; however, the challenges of achieving acceptable water application uniformities and preventing local runoff are greatly increased. This is the third of a three-part series helping growers consider in-canopy vs. above-canopy sprinkler packages.

In-Canopy vs. Above-Canopy Sprinklers: Which is Better Suited to Your Field? (Part 2)

March 26, 2018
Center-pivot irrigation sprinkler package designs need to account for the specific pivot, the available water supply, and various attributes of the field where the pivot will be installed. Learn what to consider in this second article of a three-part series assessing in-canopy and above-canopy sprinklers and which is best for a given operation.

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.
