Because soil organic carbon (SOC) can operate as both a drain and a source of atmospheric CO2, it is critical to understand the amount and composition of SOC in terrestrial ecosystems, as well as the surface geographical variation in SOC and the underlying mechanisms that stabilise SOC. For sediments and soil.
A-horizons from around the world, the relationships between mineral specific surface area and organic carbon (OC) concentration were investigated. Organic components can be absorbed by the surface of minerals, and there is a positive relationship between specific surface area (SSA) and OC. Much of our current understanding is based on laboratory research, the results of which frequently contradict field observations.
