Soil properties and carbon dynamic following peatland drainage; Management strategies to reduce soil organic carbon loss from drained peatlands
In the course of the discussion about carbon sequestration potentials in soils, scientific attempts of how to restore the C sink or to reduce the climatic impact of organic soils and finally to implement them in climatic migitation strategies are rapidly emerging. Rewetting and restoration of natural peatlands is the main option to avoid SOC losses, while at the same time increasing CH4 losses and economic losses as main trade offs. The first major rewetting activities occured in the temperate and boreal zone at sites, which were not intensively used before. Therefore, research up to now has focused on little or comparably moderately degraded peatlands, which were rewetted with the aim of re-establishing the origin habitat conditions or of restoring peat extraction sites. Owing to their high emissions, the demand for mitigation and rewetting activities shifted to more intensively used peatlands as well.
