Popis: The objectives of this study were to determine the frequency of nitrogen-fixing cyanobacteria, algea and total number of bacteria in different types of soil of Vojvodina province. The presence of these groups of microorganisms in the vertical profile of each soil type was also determined. Microorganisms were studied in five soil types: chernozem, fluvisol, arenosol, solonetz and humogley. The highest number of nitrogen- fixing cyanobacteria and bacteria was obtained in solonetz while the highest number of algae was determined in fluvisol. The number of investigated groups of microorganisms in the analyzed soils were found to be depended on soil type and soil profile depth. The numbers of the microorganisms under study typically decreased with soil depth. The obtained results show us that the strains of nitrogen-fixing cyanobacteria isolated from local soil may be used through biotechnological application in the development of microbiological inocula which are effective in temperate climatic conditions.
