Multi-scale controls on soil organic matter: leveraging networks, synthesis, and long-term studies
Session ID#: 77676
Session Description:
Soil organic matter (SOM) is a critical ecosystem variable regulated by complex physical, chemical and biological interactions across scales. Better constraints on SOM pools and fluxes are required to advance understanding and generate insight into how global change will influence SOM persistence and vulnerability. Interdisciplinary research and observation networks are collecting long term, geographically distributed data that can help elucidate mechanisms driving soil organic matter dynamics, and international efforts are working toward soil data harmonization and data-model sharing.
We seek contributions investigating controls on soil organic matter using a networked, multi-site approach and/or leveraging long-term observations or experiments. Studies using novel tools, from microbial -omics to near-surface geophysical and remote sensing observations, are welcome. Contributions that discuss data dissemination, cross-site synthesis, and collaborations between empiricists and modelers within and across networks, are strongly encouraged.
