The study deals with the basic chemical and microbiological properties of chernozem along the soil profile at six locations near Novi Sad, Serbia. According to the main chemical properties of chernozems, the soils were alkaline and well provided with nitrogen (except at the location of Novi Sad-Guskov Salas). The results showed that microbial activity at the site was the most intensive in the surface layer of the soil and that it decreased with depth. Total microbial abundance and the presence of ammonifiers and oligonitrophillic microbes were high. Azotobacters, which are important indicators of the nitrogen fixation balance, were found in all locations. The presence of fungi was higher then the presence of actinomycetes, except at the locations of Kovilj and Novi Sad-Guskov Salas. At the location of Irmovo the presence of dehydrogenase as an indicator of the oxidation-reduction processes in the soil was extremelly high down to 20 cm depth, but further down it decreased with increasing depth.
