Basing on two long-term model experiments (microplots as well as greenhouse pot experiment) the influence of extreme management on a very easily decomposable pool of soil organic matter (SOM) was measured. The carbon content (C hwe ) of a hot water extractable pool of SOM was used as an indicator for the decomposable C pool. This parameter reflects both the dynamics of the amount of decomposable organic C pool and the different transformation conditions in case of the pot experiment (outside versus inside the greenhouse). Depending on soil type and both the total and decomposable organic matter level at the starting point of the experiments we can observe differences in the decreasing speed of the decomposable C pool: in the soils having a high level of SOM at starting point C hwe pool decreases more rapidly compared to the soils unfertilized or in case of the only P and K treatment of the Static Fertilization Experiment at the beginning of the pot experiment. At least we can observe a difference in decreasing intensity of this C hwe pool when comparing different soil types.
