Irrigation Engineering

Kansas has nearly 3 million irrigated acres. State water law requires that water be used beneficially for the overall good of the citizens of Kansas. Approximately 85% of the water in Kansas that is diverted from groundwater and surface water supplies is used for irrigation. Although this irrigation water is utilized on only 14% of the cropland, it accounts for 33% of the state’s crop production. K-State Research and Extension is committed to developing and promoting new irrigation technologies that will be environmentally and economically efficient while conserving and protecting limited water resources. This site is devoted to general irrigation information and practices.

The goal of the water management research program at the SWREC, Garden City, is to develop management strategies and technologies that improve water productivity and maximize net economic returns of water-limited irrigated cropping systems. Our research focus is on three areas including deficit irrigation management and modeling for grains and forages, improving water application efficiency using Mobile Drip Irrigation (MDI), and integrated irrigation scheduling. Current outreach/extension activities involve demonstrating the benefits of reduced tillage and residue management on soil water storage in water-limited cropping systems.
