      abstract     = {The microbial communities in agricultural soils are
                      responsible for nutrient cycling and thus for maintaining
                      soil fertility. However, there is still a considerable lack
                      of knowledge on anthropogenic impacts on soils, their
                      microflora, and the associated nutrient cycles. In this
                      microcosm study, microorganisms involved in the conversion
                      of crop residues were investigated by means of classical
                      microbiological and molecular methods such as denaturing
                      gradient gel electrophoresis (DGGE) of PCR (polymerase chain
                      reaction) amplified 16S rRNA genes. 14C-labelled maize straw
                      was humified by the naturally occurring microflora in native
                      and in ashed soils, from which organic carbon was removed by
                      heating at 600°C. The humic acids synthesized in the
                      microcosms served as indicators of the humification process
                      and were analysed by 13C-NMR spectroscopy. Ashed, autoclaved
                      and native soil exhibited similar microbial and
                      physicochemical dynamics after inoculation with a soil
                      suspension. Bacterial counts and DGGE analyses showed that
                      in the first few weeks a small number of rapidly growing
                      r-strategists were principally responsible for the
                      conversion of maize straw. As the incubation continued, the
                      bacterial diversity increased as well as the fungal biomass.
                      13C-NMR spectroscopy of 26-week old soil extracts revealed
                      that structures typical of humic substances also evolved
                      from the plant material.},
