Researchers at Kansas State University are developing precision irrigation systems that use satellite data and field sensors to give crops exactly the water they need, helping farmers in western Kansas conserve the declining Ogallala Aquifer while also boosting crop yields. The project is led by the Kansas Water Institute, with Gaurav Jha's lab at K-State playing a key research role.

Why it matters

The Ogallala Aquifer, which provides water for much of western Kansas agriculture, is being depleted at an unsustainable rate. Precision irrigation offers a high-tech solution to this pressing water scarcity issue, allowing farmers to reduce water usage while maintaining or even increasing crop productivity.

The details

The precision irrigation system combines satellite imagery and in-field sensors to precisely monitor plant stress and water needs across a farm. This allows farmers to apply water only where and when it's needed, rather than using a one-size-fits-all approach. Researchers say this could lead to lower costs and stronger yields for Kansas farmers in the long run.

  • The Ogallala Aquifer has been depleting at a 'very high rate' in recent years.
  • Gaurav Jha's lab at K-State has been involved in the precision irrigation research project since it began.

What they’re saying

“This aquifer is depleting at a very high rate.... We are losing our water and our resources at a very drastic level.”

— Gaurav Jha, Assistant Professor of Precision Agriculture, Kansas State University

“In the long run, if it's economically feasible, and it ties with the return on investment for the farmer, they will by it. And we've seen some technologies having a higher footprint from year one, when I started working, and year three.”

— Gaurav Jha, Assistant Professor of Precision Agriculture, Kansas State University

What’s next

Researchers will continue to refine the precision irrigation technology and work to make it more affordable and accessible for Kansas farmers, in order to help conserve the Ogallala Aquifer while boosting agricultural productivity.

The takeaway

By developing innovative precision irrigation systems, Kansas State University is providing a high-tech solution to the critical water scarcity issues facing the state's agricultural heartland. This research has the potential to help Kansas farmers save water, reduce costs, and increase crop yields - a win-win for the environment and the economy.
