Abstract

In the conditions of vertical zonation of irrigated typical sierozems in the Bostanlyk district of the Tashkent region, the composition of trace elements, humus content, and enzymatic activity were comprehensively studied. The research results showed that in the upper layers of the soil, the activity of microbiological and biochemical processes, as well as the concentration of trace elements, is high and decreases as depth increases.
