Importance of Biodiagnostics and Irrigation Gray-Brown Soils

摘要

A comparative study of the biological parameters of gray-brown soils in natural cenoses and agrocenoses is an actual problem and has great practical importance. The article shows the results of modern scientific research in the field of biodiagnostics of gray brown soils. These studies make it possible to use biological indicators not only in morphological description, but also systematics and biological diagnostics of gray-brown soils. For the first time in the study area, a comparative study of the number of phytocomplexes was carried out and the importance of studying other diagnostic biological indicators was determined. Biological studies of gray-brown soils can be used as biodiagnostic tests in the systematization and classification of gray-brown soils formed in arid ecosystems. Biological diagnostics are important for conducting biological tests and determining the suitability of the soil for agriculture [10]. Along with the study of biological parameters in moist soils of natural cenoses and irrigated soils of agrocenoses, the total moisture content of these soils was studied in different seasons. The qualitative composition of irrigation water in different seasons has been studied for 3 years and the positive impact on irrigated lands was determined. The article presents some results of studies carried out on the Goychay River and its floodplains over 3 years. In accordance with the hydrographic regime and relief of the Goychay River, the qualitative composition of the water flowing in different parts of the river, dependent particles, impurities, and the degree of clay content were studied. The article shows the bio-diagnostic properties of the soil, the qualitative and microbiological composition of irrigation water in agrocenoses, as well as in natural cenoses of the study area. It was found that irrigation water has a positive effect on soils and plants of agrocenoses.
