Metals matter: developing a metal analysis lab for the Dairy Innovation Hub
This project expands research capabilities at UW–River Falls by creating a new metal analysis laboratory. The lab will provide advanced technology to detect and measure trace metals in soil, water, feed, and dairy products—information that is critical for understanding environmental quality, farm management, and food safety. With the ability to analyze more than 70 elements at very low levels, the new system will give researchers and partners powerful tools to better study how metals move through agricultural systems.
By adding this capability, the project will support new research, lower testing costs, and make high-quality analysis more accessible to farmers, agencies, and community partners. It will also enhance hands-on learning for students by providing experience with industry-standard equipment and real-world samples. Overall, the project strengthens UW–River Falls’ ability to support sustainable dairy production, protect natural resources, and ensure safe, high-quality food systems in Wisconsin and beyond
