Session Description:
Soil respiration (Rs) is an integrating metric of ecosystem metabolism. Recent years have seen a proliferation of instrumental and data-analytical tools that allow disentangling the diversity of biological processes that occur in the soil medium. The separation of and feedback between free-living microbes and the rhizosphere, the use of different energy sources, the extent and mechanisms of carbon processing and stabilization are all seen through a different lens today than even a few years ago. Despite these advances, soil carbon dynamics remain one of the key uncertainties in ecosystem and Earth System models. We invite contributions that demonstrate improved mechanistic understanding of soil carbon processing through the combination of modeling, experimental, observational and meta-analytic techniques, with the goal of improving the representation of these processes in ecosystem and Earth System models.
