Research Interests:
Peter M. Groffman has worked at the Hubbard Brook Experimental Forest since 1992. His research interests are in soil microbial ecology and carbon and nitrogen dynamics. Specific research efforts include long-term monitoring of soil microbial biomass and activity, investigation of snow depth as a regulator of soil freezing and nitrogen dynamics, the effects of atmospheric nitrogen deposition on nitrogen gas fluxes, and effects of a whole watershed calcium addition on soil nitrogen and carbon cycling.
