The Elemental Composition of Soils of Saline Agrolandscapes and Sanitary-Hygienic Conditions of the Southern Part of the Prichanovskaya Depression
Journal Title: Open Access Journal of Environmental and Soil Sciences - Year 2019, Vol 2, Issue 1
Abstract
Studying the macro- and microelement composition of the soils of the saline agrolandscape of the southern part of the Prichanovskaya depression, it was established that meadow-chernozem poorly saline sandy soil was formed in the eluvial position, and low-saline solonchikovy clayey soil in the bottom. Of macronutrients in them is dominated by silicon. Calcium is more than magnesium, especially in the soil horizons of the lower position. The content of trace elements in the soil of the lower position is 2-3 times higher than at the top due to their movement with surface and groundwater. The content of arsenic, barium, boron and strontium is several times higher than the MPC, which creates a difficult situation in the area, which must be considered in the production of agricultural products. Currently, agricultural production is undergoing great changes. The main direction of use becomes its greening on a landscape basis. The founder of this direction is BB Polynov [1]. The landscape is a large and complex dynamic system of the earth’s surface, within which interaction and interpenetration of the elements of litho, hydro, and atmosphere occur [2]. In connection with the agricultural use of the territory, a variety of landscape began to stand out-an agroland landscape, which takes into account all its peculiarities of development and existence-climatic, biological, lithological, soil, etc. Such major scientists - soil scientists as VA Kovda [3], Kiryushin VI [4], who were forced to look at this problem differently than in the previous research period. Earlier, in the development of zonal farming systems for the rational use of soil cover, zonal features of the territory were mainly taken into account. It turned out that with soils and living organisms in it and on it, scientific substantiation, accuracy and thoroughness of agrotechnical and ameliorative treatment is necessary. Underreporting and lack of knowledge of natural conditions, especially of the soil cover, is one of the reasons for low yields. With the scientifically based and effective management of soil fertility, two difficult tasks are solved: obtaining high and stable yields and increasing soil fertility. At the same time, it is important to know the chemical composition of soils belonging to a particular landscape and the direction of geochemical processes within it. The purpose of these studies is to study the chemical elemental composition of the soil and the sanitary and hygienic situation in the saline agrolandscape of the southern part of the Prichanovskaya depression, which is part of the Barabinskaya plain
