Transforming nitrite and nitrate analysis through new analytical enhancement
This project expands analytical capabilities at UW–River Falls by introducing advanced technology for measuring key nutrients such as nitrate and nitrite—important indicators of soil health, water quality, and dairy system performance. The new automated system can process multiple nutrients at once, handle sample preparation steps automatically, and significantly increase the speed and efficiency of analysis.
By increasing capacity and flexibility, the project allows researchers, students, and external partners to conduct more complex and wide-ranging studies. It supports work on nutrient runoff, groundwater quality, food safety, and animal health, while also reducing costs and improving access to high-quality testing. Overall, the project strengthens research, enhances hands-on learning, and supports innovative solutions for sustainable dairy and environmental systems in Wisconsin.
