Resumo: | The first months of the year were dedicated to preparatory work in Germany and in Brazil. In July we finished the unexpectedly time-and cost-intensive installation of a generator and no break system to maintain the functioning of extraction and analyzing equipment (Kempson and Berlese-extractor, C/N-analyzer and Infra-Red-Gasanalyzer IRGA) during the very frequent breakdowns of the power supply in the laboratory of the EMBRAPA institute. On 23/24 July the joint "central sampling program of macro-and mesofauna, oligochaeta and microflora which includes field and laboratory work was successfully tested. On 27 october the first litterbag series with 1008 litterbags containing air-dried Vismia-litter to evaluate site-specific decomposition rates was distributed in the study sites. The retrieval of the bags from reandomized positions startes 4 weeks later has gone on since then. Together with the litterbags a series of minicontainer bars was distributed in the field as a second method to measure decomposition rates. The minicontainer system is tested as an alternative to the litterbags. Another short-assessment method, bait lamina which measure general unspecified soil fauna feeding activity, was tested in july; its regular use started in december. In this report, first data are presented.
