The paper shows the results of studies of denitrification activityin root zone of spring barley, maize and potato under the use of mineralfertilizers and microbial preparations. It was established that applicationof optimal for the plants growth and development doses of fertilizershad restrained the biological denitrification activity due to the bothplants assimilation of mineral nitrogen and deprivation of rhizosphericmicroorganisms with nitrite respiration substrate. Use of physiologicallyungrounded doses of fertilizers especially when combining withmicrobial preparations had led to the significant loses of nitrogen dueto the denitrification. Thereby the application of microbial preparationsin agricultural crops growing technologies should be performed onoptimal agricultural backgrounds keeping biological denitrification atits lowest levels.
