[Dynamics of the number of soil bacteria calculated by different methods]

Temporal changes in the incidence of soil bacteria were estimated using different methods such as luminescent microscopy, direct count according to Vinogradsky, growth on MPA. The method of Vinogradsky gave less stable results as compared to luminescent microscopy. The method of calculating microorganisms was found to influence the results obtained while studying the temporal dynamics of bacterial incidence in sod-podzolic soil.
