The aim of the study was to investigate the influence of the no-plowing tillage on the development of two trophically differentiated groups of microorganisms (oligotrophic and copiotrophic bacteria) and on the quantitative relationships between there microorganisms, expressed as the O – to – C coefficient. For the verification of the hypotheses under study factorial block model with two factors – type of soil cultivation and depth of soil layer – and test days as blocks was used.
factorial block model, no-plowing tillage, oligotrophic bacteria, copiotrophic bacteria.
