The dynamics of nitrogen fixation, emissions of N2O and CO2 in pea agrocoenoses under the influence of different fertilization systems and pre-sowing seeds inoculation with microbial preparation Rhizohumin were studied in stationary field experiment on leached black soil (short crop rotation potatoes – spring barley – peas – winter wheat). It was observed that symbiotic nitrogen fixation process had become active on the second year aftereffect of 40 t/ha of cattle manure, green manure and use of low (N30P30K30) and medium (N60P60K60) doses of mineral fertilizers. Rhizohumin had significantly increase nitrogen fixation activity in all variants except of the one with manure. Increase of N2O emissions had corresponded to the increasing doses of mineral fertilizers. The use of biological preparation had ensured the reduction of gaseous nitrogen losses due to the initiation of plants development. Carbon dioxide emission values had depended on the type and dose of fertilizers. Rhizohumin had reduced the emission of gaseous carbon compounds in variants with different fertilizer backgrounds due to its extensive use in the formation of additional yield.
