BIOLOGICAL ACTIVITY OF IRRIGATED MEADOW-ALLUVIAL SOILS DEPENDING ON THE DEGREE OF SALINATION

Abstract

The article discusses some features of the enzymatic activity of old-irrigated and newly-grown meadow-alluvial
soils of the Bukhara oasis. determination of the factors causing salinization, its prevention, as well as preservation,
reproduction of fertility and rational use of saline soils in agriculture, in conditions of a constant increase in the area
of saline soils as a result of natural processes and anthropogenic influence, are priority tasks. As the results of studies
show, the microbiological properties of soils change under the influence of salinity. Along with this, there is a change
in the number of microorganisms depending on the season. The variety of physical and chemical properties of the
studied soils is reflected in the distribution of soil enzymes. According to the research results, there was a significant
change in the number of studied microorganisms depending on the degree of salinity
