In 2012-2017, the activity of bacteria, ray fungi and microscopic fungi from microorganisms was studied in field experiments with the aim of studying the effect of micronutrients on the productivity of winter wheat in moderately eroded gray mountain-brown soils. The regularity of the activity of the microorganisms that play a major role during the vegetation period of wheat was studied. It was found that the micronutrients given to the soil increased the activity of groups of microorganisms in all variants of the experiment. Thus, the effect of micronutrients on the activity of bacteria was greater. Likewise, micronutrients also increased the activity of fungi and fungi. has increased. The activity of bacteria and fungi has increased. Also, does this group of microorganisms develop better, especially in conditions without humidity? From these 5-6 years of research carried out by us, we can draw the conclusion that microelements significantly revive the microbiological process in eroded soils, as a result of which decomposition and synthesis of decay in the soil is significantly improved, and the process of humus formation is accelerated.
