The article presents data obtained from the analysis of the ecological and biological state of meadow-alluvial soils in the desert region. According to the results of the seasonal dynamics of biological activity of meadow-alluvial soils common in the desert zone, the highest biological activity was observed mainly in spring. The reason for this is the presence of favorable hydrothermal conditions and nutrients for biological processes at this time. It was also found that the change in the overall biological activity of the soil depends on the content of humus and nutrients, mechanical composition, age of irrigation and the degree of salinization. Thus, the obtained results show that the integral indicator of soil biological activity can be widely used in assessing the response of regional soils to external influences, as well as the effectiveness of measures taken to preserve and improve soil fertility.
