The paper deals with effects of nitrification inhibitor N-serve 24-E (C6H3NCl4) on the number (total bacteria, fungi, actynomycetes, ammonifiers, denitrificators and azotobacter) and proteinase of the microorganisms in the alluvium and smonitza soil under spring varieties of barley and wheat, as well as on some quality traits of the studied plants (height, the number of leaves and dry matter). It has been shown that all studied factors (in our case, plant culture, soil type, inhibitor) significantly affected all of the tested biological parameters whose interaction effect was also apparent. N-serve has shown the highest inhibitory effect on azotobacter, denitrificators and soil fungi, whereas, it simultaneously stimulated the growth of ammonifiers. Inhibitory effect of N-serve was mostly pronounced in the alluvium under barley. High amounts of nitrification inhibitor did cause a decrease in plant height but they did not essentially change the number of leaves and content.
