Research Data Sets: Biogeochemical Dynamics
Our work on biogeochemical processes represents an integral part of our conceptual framework. We conceive of biogeochemical processes as integrated functions of biotic components, those processes responsible for C and other nutrient fluxes in the ecosystem: NPP, decomposition, weathering, nutrient mineralization and availability, and trace gas flux. These processes are influenced by climate, biotic interactions, physiography, and natural and human-induced disturbances. Our work in this area is organized around 5 major hypotheses. We address these hypotheses through continuing long-term measurements, short term experiments, new long-term experiments and simulation modeling. Below, we describe our work associated with these hypotheses.
