The soil organic carbon (SOC) pool and composition of forest soils are related to local site conditions. Future climate changes will induce an increased frequency of forest dieback, resulting in modified site conditions, affecting the SOC pool of the forest soils. The objectives of this study were to study (1) the chemical composition of mineral-associated soil organic carbon of acidic forest soils, (2) the spatial variability of SOC stocks in soils of forested landscape units, and (3) long-term effects of forest disturbance 25 years ago on SOC pools and composition.
The study revealed that specific compounds of the SOC pool are preferentially stabilized in acidic subsoils, and that SOC pools of humic topsoil horizons are highly sensitive to forest disturbances.
