Secondly, the session will address how thermodynamic considerations can help to understand the transformation, degradation and stabilization of soil organic matter (SOM). SOM is increasingly seen as being comprised of biomolecules that are the result of microbial metabolism, including microbial biomass components and microbial-processed plant compounds.
Heterotrophic living microbes require energy delivered by the oxidation of organic matter. Soil systems, their biodiversity and ecosystem services are thus underpinned by mass and energy flows of organic compounds, in particular at hotspots of microbial activity, e.g. the rhizosphere. The formation of bio- and necromass as well as the storage of SOM are subjected to the laws of thermodynamics. Exploring the measurement of the SOM energy content and the regulation of the energy and matter flux processes has the potential to complete the knowledge of ecosystem control. In a wider perspective, bioenergetics and thermodynamics of soil systems may provide information on the development of sustainable and robust management of soils as ecological systems under climate change.
We therefore welcome experimental and modelling studies on rhizosphere functioning that aim at revealing spatial gradients of e.g. functional biodiversity of microorganisms, uptake and release patterns by roots, soil structure modification by root growth and feedbacks among them. This session also invites contributions presenting and discussing recent developments for the integration of thermodynamics in soil systems, including analytical developments as well as conceptual, empirical and modelling approaches.
