B33D:
Soil Organic Matter: Mechanisms of Stabilization and Change II Posters


Session ID#: 10321

Session Description:
Soils are essential components of the Critical Zone, and are both responders and drivers of the most critical environmental changes facing the earth during the Anthropocene. Soil organic matter dynamics play a major role in determining C storage in ecosystems and in regulating atmospheric CO2 concentrations. How will climate change and man’s alteration of the terrestrial landscape affect soil organic matter dynamics? This session will focus on empirical and modeling studies of soils and carbon: storage potential, mechanisms of stabilization/ destabilization/ long term storage, and ecosystem vulnerability.
