In recent years there has been increasing evidence that besides abiotic drivers, biotic effects may also strongly influence biogeochemical processes. This session aims to highlight the implications of interactions between plants and soil biota for ecosystem carbon (C) and nutrient dynamics, and how these are altered by global change. Topics range from C allocation in the plant-soil system and its consequences for soil respiratory fluxes, soil organic matter turnover and nutrient mineralization, to effects of plant traits and vegetation composition on C and nutrient cycling at local, regional and global scales.

Confirmed keynote speakers: Peter Högberg (Umeå) and Mark Bradford (Yale)
