Montana State University Wins $600K Grant to Fight Bacteria in Hydroponic Farms

Montana State University secured a $600,000 USDA grant to develop bacteria-removal technology for hydroponic farms.

Researchers at MSU’s Department of Mechanical and Industrial Engineering, led by Stephan Warnat, are creating a nanoparticle-based system to detect and filter harmful microorganisms that threaten hydroponic crops. This effort aims to protect year-round production without soil, a vital adaptation for regions with harsh winters and vulnerable water systems.

The technology works by using nanoparticles to capture microorganisms, forming clusters that can then be filtered out of the circulating water. This approach addresses a key vulnerability in hydroponic setups, where shared water can rapidly spread bacteria. MSU’s mission includes making this technology practical for farmers, with plans to teach them how to interpret system data.

Researchers hope to bring these innovations to Montana farmers, supporting local agriculture through their land grant mission.

While the technology is still under development, it could prove especially valuable in Montana’s climate, where dry soil and cold winters limit traditional farming. Hydroponics offers a controlled environment that may reduce risk and extend growing seasons, potentially reshaping local agricultural practices.
