Soil Organic Matter and the Global Carbon Cycle: Mechanisms for Accumulation and Loss in a Changing World IV Posters

Submit an Abstract to this Session



Session ID#: 27344

Session Description:
The reservoir of carbon contained in soil organic matter is exceedingly large. However the mechanisms for it’s accumulation, retention and loss are not well understood. Our ability to predict how climate change and man’s alteration of the terrestrial landscape affect soil organic matter dynamics ultimately depend on a deeper understanding of the underlying mechanisms. 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. Isotopic, geochemical, spectroscopic and other novel molecular techniques that probe deeper into the fate and function of organic matter across spatial and temporal scales are especially encouraged.
