Drained soils as an analogue of a large area lysimeter

Abstract

Surface waterlogged soils, drained by ceramic and plastic drainage, are an analogue of large-area lysimetric installations, the drainage runoff in which is represented by gravitational waters like lysimetric waters. The drainage runoff module in the spring and autumn periods at landfills drained with plastic and ceramic drainage, and its dependence on the humidity of the year have been established. It is shown that drainage transforms the type of water regime from stagnant-washing to washing. The long-term and spatial dynamics of the removal of the silty fraction of soils and iron compounds has been studied. The removal of chemical elements with drainage runoff and its influence on the intensity of the loessivage process in agro-gray drained soils have been established.
