B33G:
Soil Carbon Dynamics at Broad Scales: Linking Mechanistic Knowledge to Broad-Scale Applications I

Submit an Abstract to this Session



Session ID#: 31943

Session Description:
Soil carbon is a key component of biogeochemical feedbacks within ecosystems, as well as climate feedbacks on regional to global scales. Soil carbon dynamics are often studied on fine spatiotemporal scales but the climate implications of these dynamics are typically on coarse scales. Thus, a critical challenge in soil carbon science is to scale process-level understanding to management- or climate-relevant applications.

This session welcomes contributions that focus on broad-scale soil carbon dynamics (regional to global or decadal to millennial scales). We invite empirical, modeling, meta-analytical or review studies as well as studies harnessing ‘big data’ in soil carbon science, including those using data from research networks such as International Soil Carbon Network (ISCN), Critical Zone Observatory Network (CZON), National Ecological Observatory Network (NEON), etc. We also welcome contributions bridging mechanistic understanding of soil carbon to broad-scale applications such as soil health, management best practices, climate mitigation, etc.
