Researchers with the University of Nebraska-Lincoln will use the Arable Mark IOT device to record 40 variables in Nebraska farm fields as part of a research effort to improve data farmers use to determine whether they should irrigate.

Researchers to Tackle Irrigation Decision-making with Help of USDA grant

October 30, 2019
A new federally funded, multi-state research project aims to bridge the gap between data-collection in the field, modeling, and decision-making so crop producers can more easily decide whether to irrigate. The project could help growers save financial and water resources.

Nebraska Continues To See Modest Groundwater Decline

March 15, 2018
Based on tests in 5,200 water wells across the state, Nebraska has seen a modest decline in groundwater levels in the last five years. A new university report tracks well levels in 1-year, 5-year, 10-year, and pre-irrigation increments to identify trends.

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.
