Soil organic carbon (SOC) and inorganic carbon (SIC) are fundamental to the maintenance of the ecosystem services provided by soils. SOC is dynamic and reactive, resulting in a complex array of interactions between it and the soil mineral phase or metal species. These dynamic interactions are ultimately linked to the persistence and accumulation of SOC across scales ranging from micro- to global scale. This session is dedicated to studies investigating the dynamic interactions, underlying mechanisms, and implications of organo-mineral and organo-metal interactions at different scales. It includes studies on the quality, type, and sources of SOC (e.g. plant, microbial, pyrogenic), its storage within aggregates, and its association with mineral surfaces or metals across all pedoclimatic settings and their responses to management practices. However, we also welcome studies that investigate both SOC, SIC, and their interactions utilizing a broad range of analytical techniques including field, laboratory, modelling, and spectroscopic approaches. We put emphasis on contributions addressing the biogeochemical effects of different mineral amendments such as rock (e.g. silicate rich rock) powder on both the inorganic and organic carbon cycle of soils. This session thus aims to enhance our mechanistic understanding of the interactions between soil carbon and minerals at different weathering stages or metal species across scales in all pedoclimatic settings.
