Application-oriented carbon budget modeling of organic soils

Our results show that the water balance is the most important parameter for estimating greenhouse gas emissions from organic soils. This applies not only to individual sites, but also on a large scale. The precise description of hydrological processes of organic soils can only be achieved with models designed for this purpose, which require more extensive parameterization than is the case with mineral soils. This is particularly relevant for processes during rewetting measures and their success assessment.

The necessary parameter scope is not implemented in current regionalization approaches. Therefore, future work should aim at the extensive integration of existing parameter databases from soil hydrological modelling into regionalisation approaches in order to improve emission reporting for organic soils.
