Soils in the Anthropocene: Cross-scale Mechanisms of Stabilization and Change
Soils in the Anthropocene: Cross-scale Mechanisms of Stabilization and Change
Session ID#: 247219
Session Description:
Soils play a major role in provisioning key ecosystem services, including nutrient supply, carbon (C) storage, and regulating atmospheric greenhouse gas concentrations. Better constraints on the cross-scale mechanisms that regulate soil C pools and fluxes are needed to improve understanding and provide insights into how global change will affect soil C persistence and vulnerability. This session will focus on empirical, synthesis, and modeling studies that address the stabilization and change of soil C, including but not limited to: storage capacity, ages and transit times of soil C, soil fluxes and pools, interactions with nutrients and metals, mechanisms of protection and stabilization/destabilization (including new methods to measure and monitor change), and ecosystem vulnerability. Studies involving manipulation experiments (e.g., precipitation, litter), long-term or large-scale data collection or synthesis, and model-data integration are strongly encouraged.
