SUMMARY
One of the most represented types of soil in the hilly- mountainous region of Eastern Serbia
is the dystric cambisol. Aiming to establish biogenity of such type of soil in Eastern Serbia,
representation of the total microflora, fungi, actinomycetes, ammonifiers, azotobacters and
oligonitrofills has been examined as well as dehydrogenase activity of the stated type of
soil. The samples were taken from soils used in three different ways: plough-fields, orchards
and forests. The standard microbiological methods of introducing in certain decimal
dilutions on the appropriate nutritive medium were used. The obtained results have shown
the most prevalence of total microflora in the plough-fields. No correlation between other
groups of microorganisms and the way of using of soil was determined. Small partipication
of azotobacters, as crop production indicators, was found in the forest regions. No correlation
between dehydrogenase activity of tested samples and total microflora was determined.
Key words: biogenity, dystric cambisol, microflora
