THE DRAINING OF THE ACQUITARD MINERAL SOILS
Abstract
The results of the analysis concerning the effectiveness of draining of badly pervious mineral soil with the help of horizontal drainage in Postavy and Braslav districts of Vitebsk region and various methods of loess loam draining in Mstsislav district of Mogilev region on dish relief are given in the article. The positive role of drainage on the acquitard soils with plain relief is noted. The periodicity of drainage effectiveness and a great influence of water permeability of drainage filling are established. Most effective draining of loess loam on dish relief is reached on the areas which were drained using the solid and punctate filled selective sand-gravel drainage of separate drains to a plough-layer level. In case of >0.005 surface slope it is recommended to limit the usage of systematic drainage. It is stated that under-hollow collectors should be arranged differentially as consistent with surface relief.
