The biological activity of the rhizosphere soil increased upon the application of mineral fertilizers (N18P42) and their combination with straw (N18P42 + straw) by 58 and 70 %, in comparison to the control. Of the three studied factors, the application of mineral fertilizers had the highest positive effect on the number of microorganisms in the barley rhizosphere, both separately and in combination with the studied factors.
