Microbial properties were examined according to profile depth in the following five soil types: fluvisol, hydromorphic gley soil, colluvium, solonetz, and chernozem. Soil samples for microbiological analyses were taken in June of 2005. Overall soil biological activity was monitored based on total microbial abundance and the number of diazotrophs, ammonifiers, actinomycetes and fungi. In all of the soil types biological value was high down to 30 depth. Total microbial abundance decreased with increasing soil depth and no fungi or actinomycetes were found in the deeper layers. Total microbial abundance and the number of ammonifiers and free N-fixing bacteria were the highest in solonetz. The most azotobacters were found in the hydromorphic gley soil, while fungi and actinomycetes were the most abundant in fluvisol.
