The microbial release of nitrogen (N) from soil organic matter (SOM) is the underlying process for plant growth in many terrestrial soils. The prediction of the N background supply also determines the quality of agricultural simulation models. Nevertheless, the progress in the theoretical understanding of SOM are only gradually translated into new...
