MODERN FEATURES OF CHANGES IN THE WATER REGIME OF CHERNOZEMS UNDER THE INFLUENCE OF FOREST BELTS
Abstract
The research was conducted in the conditions of the South-East of the of the Central-Chernozem zone (Kamennaya Steppe) in 2018-2020 biennium. Features of formation of reserves of productive moisture in agroforestry complex are shown. Data for studying changes in soil moisture profile are presented. The first decade of the current century was characterized by a widespread rise in the ground water level (GWL) to 1.2-2 m and the formation of seasonally waterlogged soils. In the dry conditions of 2010, the most critical conditions developed. The entire 200-cm layer of soil in the summer was characterized by a complete lack of available moisture. In the following years, up to 2020, at all research sites, the GWL fluctuates in the range of 3-4 m.
