      abstract     = {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 pesticide side
                      effects on the soil processes, detailed knowledge is
                      required about the structure and function of the soil
                      microflora. Therefore, the degradation and humification of
                      C-14-labeled maize straw was studied in process-oriented
                      microcosms, Apart from a native orthic luvisol, a
                      heat-treated soil was used that has been freed from organic
                      carbon by incineration at 600degreesC. Microbial communities
                      involved in the turnover of the crop residues were
                      investigated using denaturing gradient gel electrophoresis
                      (DGGE) of 16S rDNA sequences. Both C-13-nuclear magnetic
                      resonance (NMR) spectroscopy and gel permeation
                      chromatography were used to analyze humic acids produced in
                      the microcosms. To evaluate the sensitivity of the
                      microcosms, the influence of the fungicide dithianon was
                      used in a case study at a concentration of 50 mg/kg.
                      Microbial activity was reduced because of the application of
                      the pesticide, especially in the native soils, while
                      mineralization of C-14-labeled maize straw was only slightly
                      affected. The buildup of fungal biomass was inhibited for at
                      least three weeks. Despite these effects on the microbial
                      communities, no significant differences in the humification
                      products after 26 weeks of incubation were observed.},
