Denitrification in prairie potholes

Denitrification is a crucial aspect of the N cycle, transforming terrestrial N into atmospheric N.  While this can reduce eutrophication of aquatic systems, it can also product N2O, a potent greenhouse gas.  At present there is a critical need to understand the underlying microbiology that drives denitrification so land managers can maximize the benefits of denitrification and minimize greenhouse gas emissions. Our research consists of both field measurements and laboratory manipulations aimed at linking microbiology to ecosystem denitrification rates.
