The interactions among plants, soils, and microbial communities are complex and strongly influences terrestrial biogeochemical cycles. Therefore, understanding the underlying processes and large-scale patterns of how environmental changes impact soils across pedo-climatic regions is essential for developing sustainable land management options and accurately representing major biogeochemical fluxes in land surface models.

We invite contributions to this session exploring the impacts of environmental change on plant-soil interactions, the biogeochemical cycling of carbon (C), nitrogen (N), and phosphorus (P), as well as soil microbial diversity and functionality at varying spatial and temporal scales. Contributions can be from manipulative field experiments, observations of natural environmental gradients, or modeling studies. We particularly welcome submissions that adopt novel approaches, such as molecular or isotopic analyses, or that synthesize outputs from large-scale field experiments focusing on plant-soil-microbe feedbacks. We also welcome studies that address gaps in our understanding of soil dynamics in remote and understudied regions.

This is a continuation of our earlier, successful EGU sessions on similar topics. Through this session, we aim to continue bringing people together to learn from each other's studies on soils and environmental change in a variety of global pedogenic and climatic settings.
