[Dynamics of the development of different microorganisms in soil]. / Dinamika razvitiia razlichnykh mikroorganizmov v pochve.

The dynamics of individual components from the complex of soil microorganisms (bacteria, fungi, actinomycetes) and the population of Stm. olivocinereus introduced into soil was studied by luminescent microscopy and inoculation. The population density maxima for individual components from the complex of soil microorganisms were shown to be separated in time suggesting a succession. Fungi developed at the first steps of succession and dominated in biomass over the remaining components of the complex. Bacteria and actinomycetes developed at the later steps of succession. Glucose addition stimulated still earlier growth of fungi (the maximal mycelium legth was registered by the second day) but had hardly any effect on the dynamics of other components of the complex.
