The aim of this paper was to investigate microbiological activity in barley rhizosphere, after the experiment with 17 recultivation treatments of deposols with different organo-mineral materials. The most important agrochemical properties of deposols have been examined. The presence of the microorganisms was determined by the usual microbiological mediums. Dehydrogenase activity was determined by the Cassida et al. method. The deposols were poor in organic matter, nitrogen, phosphorus and potassium. The number of bacteria ranged from 9.3 to 413.3 x 10**6/g. The addition of organo-mineral materials into deposols has caused an increase of microbial biomass and dehydrogenase activity, comparing with control.
