Hochsch., Diss., 2001 AB - The microbial communities in the soil are responsible for material cycling and thus also for maintaining the fertility of agricultural soils. In order to assess the influence of anthropogenic activity, e .g. from the application of pesticides, an the soil, its microflora and the associated material cycles, detailed knowledge is required an the structure and function of microbial communities in soils. In the present study, the microorganisms involved in the conversion of crop residues were investigated in process-oriented microcosms, amongst other procedures, by means of the denaturing gradient gel electrophoresis (DGGE) of the amplified 16S rDNA sections. The humic acids synthesized in the microcosms served as indicators of the quality of the humification process and were analysed by 13C-NMR spectroscopy and gel permeation chromatography (GPC).
