Soil microorganisms play a significant role in agroecosystems via decomposition
and nutrient cycling and may serve as indicators of potential soil fertility and land-use
change. Cultivation practices lead to disturbance of soil properties, which is manifested
by a reduced number and enzymatic activity of microorganisms, especially because
modern agricultural production involves the use of large amounts of pesticides and
fertilizers, the non-application of organic fertilizers, and the burning of crop residues.
The aim of this study was to determine the abundance of certain microbial groups and
dehydrogenase activity in arable lands of Vojvodina Province according to the humus
gradient, which is one of the most important characteristics of soil fertility.
Microbiological properties and humus content have been determined in 1115
representative soil samples collected from the surface horizon (0 –30 cm). The highest
total number of bacteria, oligotrophs, copiotrophs, and fungi, a...s well as dehydrogenase
activity, were recorded in soil samples with a high content of humus (5–10%). Similarly,
the azotobacters and actinomycetes were the most abundant in medium-humus soil
samples (3–5%), whereas the lowest microbial number and activity were detected in
soil samples with very low humus content (˂1%). The results indicate the necessity of
applying good agricultural practices that will enable intensive microbiological activity
and the synthesis of new amounts of humus, primarily through the introduction of
organic matter into the soil as well as the use of microbial-based preparations.
