Bacterization was performed with the liquid seed inoculum of the maize hybrid ZP SC 704 and the wheat variety Leda. The inoculum consisted of a mixture of selected diazotrophs and their highly effective strains. The following variants of mineral N fertilizers were used in the trial: control K, N1 - 80 kg/ha, N2 - 120 kg/ha, and N3 - 160 kg/ha. Values of parameters of soil biogeny (total number, abundance of diazotrophs, ammonifier, enzymic activities), were higher under bacterization conditions in both plant species, and were accompanied with higher grain yields. There were no significant differences in value increases of investigated parameters between fertilizing variants N1 and N2, hence it can be concluded that the application of bacterization can rationalise the utilization of mineral fertilizers, what is of a significance for sustainable agriculture.
