The microbiological indicators of soils occupied by grass, deciduous and coniferous vegetation from regions in Lozenska, Rila and Maleshevska mountains were studied. The main groups of soil microorganisms, the enzymatic activity (β-glucosidase and phosphatase) and the total biological activity of the soil (by the released carbon dioxide) are determined. It was found that in each region the combination of specific soil characteristics, climatic conditions and vegetation type cause differences in microbiological properties. In general, in the Cinnamon and Brown Forest Soils under grass vegetation from the three regions a higher amount of actinomycetes is observed compared to those under coniferous vegetation. The soils of Lozen mountain are characterized by a large number of bacteria digesting mineral nitrogen, fungi and actinomycetes. The amount of microorganisms in the surface horizon correlates with the bulk density and the C/N coefficient of the soil, which is most strongly represented in the soils of Rila Mountain. Cinnamon forest soil under grass vegetation from Maleshevska Mountain stands out from the studied soils with the best microbiological indicators, where the highest amounts of heterotrophic and cellulosedecomposing microorganisms, the highest enzyme activity and the highest total biological activity were reported.
