Changes in densities of microorganisms were analysed in Cognetia sphagnetorum Vejd. Cultures at normal and low numbers of microorganisms. Different abundance of microorganisms was achieved by using captan and oxytetracycline. During 14 weeks, the following variables were measured: total numbers of bacteria and fungi by plate method, the biomass of microorganisms by PLFA method, content of ions, and activity of acid and alkaline phosphatase and urease. Numbers of enchytraeids increased with numbers of fungi. The presence of animals reduced the activity of soil enzymes and the content of Cl, SO₄, Na, Ca and Mg ions in soil leacheates. An increase in the content of N-NO₃ and N-NH₄ was not significant.
