Screening of soil activity in different ecological systems

Abstract

The article presents the results of studies of the qualitative and quantitative composition of soil microbiocenosis in non-Black Earth Region conditions. The characteristics of soil microflora qualitative composition in natural ecosystems and in the conditions of wheat cultivation are given. The data obtained indicate the biological degradation of agricultural soils, which is expressed in a decrease in microbiological parameters in comparison with natural ecosystems soils. It is noted that the microbiocenosis determines the soil biological activity, the measure of which is the emission of carbon dioxide. It has been established that a higher emission of carbon dioxide is characteristic of soils of natural ecosystems and is associated with the vigorous activity of microorganisms. Our data indicate that, under Non-Black Earth Region conditions, the intensity of soil respiration and the activity of microbiological processes are decisively influenced by humidity, temperature, and acid-base balance.
