soil degradation

The aim of the study is to identify relationships between the agrochemical indicators of the arable layer (humus content, mobile phosphorus, exchangeable potassium, and pH values of exchangeable acidity), field moisture, and spectral characteristics of soils in order to assess the degree of erosion under the conditions of the Chuvash Republic. The studies were carried out at five test sites (14 sampling points) on sod-podzolic soils, gray forest soils, leached chernozems, and their eroded varieties.

The article presents results of firths’ ecological and meliorative conditions monitoring, level of vegetation cover degradation and dynamics of fodder land use within Aleksandrov Gay municipal district of Saratov region for the period from 1952. As the result of the research were detected 3 periods of meliorative development and impact on the state of land. The authors propose to improve the ecological and meliorative condition of agro-landscapes by reconstructing firths, reducing the size of longlines and reducing flooding rates.
