Precision irrigation systems for sustainable water use in kansas corn production
This project evaluates radar-guided and computer-controlled precision irrigation systems using multi-source evapotranspiration data to enhance water-use efficiency in Kansas corn fields. The aim is to conserve water while maintaining crop yields, vital for regions near the depleting Ogallala aquifer.
Overview
This innovative project focuses on evaluating precision irrigation systems designed to optimize water use in corn production, particularly in areas near the depleting Ogallala aquifer in Kansas. By integrating satellite-based metrics, radar-guided sensing, and computer-controlled applicators, the goal is to enhance irrigation efficiency without compromising crop yields. This approach uses evapotranspiration (ET) measurements from in-situ sensors, UAV imagery, and NASA's OpenET platform to guide farmers in making informed irrigation decisions, promoting sustainable water management.
Technical specifications
Key features:
- Utilizes radar-guided sensing for precision irrigation on a pivot system
- Employs a computer-controlled 360-degree applicator for targeted water distribution
- Integrates multi-source ET data, including in-situ sensors, UAV imagery, and OpenET, to assess water-use efficiency
- Provides evidence-based guidelines for irrigation scheduling under water-limited conditions
Technology readiness level
This technology is currently at TRL 6, which means it has been demonstrated in relevant environments with existing partnerships at Flickner Innovation Farm and Kansas State University facilities. The next steps involve further comparative evaluations and field validations to refine the irrigation strategies and promote adoption among corn producers.
About Kansas State University
Kansas State University is a comprehensive public land‑grant research university with multiple campuses and a strong applied mission. Industry partners tap a statewide extension network that connects companies to field sites, talent, and rapid outreach; campus pilot plants and analytical services enable bench‑to‑pilot scale validation, while co‑located high‑containment facilities support regulated studies. The Olathe campus in the Kansas City metro serves as an industry‑engagement hub with workforce pipelines, collaborative labs, and proximity to the Kansas City Animal Health Corridor. Research is supported by competitive federal funding from agencies such as NSF, NIH, USDA, and DOE, alongside state and corporate sponsors, and a dedicated technology transfer office streamlines IP, sponsored research, and startup formation.
