Soils in the Anthropocene: Mechanisms of Stabilization and Change

Session ID#: 161913

Session Description:
Soil organic matter (SOM) dynamics play a major role in determining nutrient supply and carbon (C) storage in ecosystems and in regulating atmospheric CO2 concentrations. Better constraints on the mechanisms that regulate SOM pools and fluxes are required to advance understanding and generate insight into how global change will influence soil C persistence and vulnerability. This session focuses on research addressing the stabilization and change of SOM, including but not limited to: storage capacity and transit times of C in soils, molecular composition of SOM, mechanisms of protection and stabilization/destabilization (including new methods for measuring and monitoring change), and ecosystem vulnerability. Studies that feature manipulation experiments or model-data integration are strongly encouraged.
