Roley Lab Watershed Biogeochemistry

switchgrass and stream

Welcome to the Roley Watershed Biogeochemistry Lab! We study nutrient transformations in freshwaters and the surrounding landscape. In particular, our research spans 3 focus areas: 1) mitigating N and P pollution in agricultural landscapes; 2) free-living nitrogen fixation; and 3) nutrient transformations in large rivers and reservoirs.
