Abstract The unfavorable climatic conditions of the desert territory are the reason for the reduced biological activity of the studied soils; the highest BA was observed mainly in spring. This is due to the presence of favorable hydrothermal conditions and nutrients for the occurrence of biological processes at this time, in summer there is a slight decrease and by autumn a slight increase in the biological activity of the soil. Also, it was found that the change in the general biological activity of soils depends on the content of humus and nutrients in them, the mechanical composition, the duration of irrigation and the degree of salinity. Thus, the results show that the integral indicator of soil biological activity can be widely used in assessing the response of the region’s soils to external influences, as well as the effectiveness of measures taken to preserve and increase soil fertility.
