Sampling of different soil types at 20 Banat locations was performed according to the soil map of the Vojvodina Province, Serbia. Chernozem, the most common type of agricultural soil, was represented with 11 samples. The other soils were represents with following number of samples: hydromorphic black soil - 5, solonetz - 2, fluvisol - 1, and cambisol - 1. The samples were taken in June 2004 from 0-30 cm depth. Standard microbiological methods were used to determine total microbial abundance and the abundance of Azotobacter, actinomycetes and fungi. The dehydrogenase activity was determined based on triphenyl formazan (TPF) extinction. Incubation time and temperature depended on the microbial group studied. The highest levels of biogeny were detected in solonetz, chernozem and humogley and the lowest in cambisol and fluvisol. No Azotobacter was found in cambisol.
