Title :
A synthesis of change in deep soil organic carbon stores with afforestation of agricultural soils
A synthesis of change in deep soil organic carbon stores with afforestation of agricultural soils
Journal :
Forest Ecology and Management
Comment :
A lot of field studies on the dynamics of SOC of afforested land sampled only in mineral soils at limited depth and ignored carbon changes in the O horizon and deep soil layers.
The dynamics of below ground C, mainly consisting of soil organic matter and root systems, are complex and poorly understood, and thus create a gap in our understanding of the C cycle in terrestrial ecosystems
A meta-analysis of the available SOC data, revealed that deep SOC stores in mineral soil change with afforestation and previous land use and plant species are important factors explaining variation
in changes to deep SOC stores. The regression analysis showed that SOC change rate at soil depths of 0–40, 0–60, and 0–100 cm was 1.33, 1.49, and 1.55 times greater than in the corresponding 0–20 cm depth, respectively.
