Indices of soil respiration are widely used for evaluation of ecosystem productivity as well as for analysis of activity of soil microbiocenosis. Evolution of carbon dioxide can be an objective index of decomposition of soil organic matter and permits to characterize one of the most important aspects of biological cycle. This article analyzes dynamics of carbon dioxide evolution rate in ordinary chernozem upon contamination with antibiotics (ampicillin, streptomycin, tylosin, tromexin, aliseryl) in the concentration of 500 mg/kg. The obtained results evidence complicated mechanism of CO2 evolution upon contamination with antibiotics. CO2 evolution rate increases after contamination with antibiotics, the evolution peaks are observed after 4?6 days from the date of incubation of contaminated samples which can be attributed to active use of water soluble organic carbon by microbial community, then it gradually deceases and the level of evolved CO2 is stabilized in general. The highest CO2 evolution rate is observed upon contamination of chernozem with ampicillin and tylosin (0.68% and 0.45% CO2/24 h, respectively).
