摘要：
FIELD: agriculture.SUBSTANCE: method comprises a device of drainage trench with a drainage pipe laid on its bottom with a protective-filtering material, the filtering elements in the form of prisms of soil of humus horizon, arranged in a trench to the arable layer, and the final backfilling the trench with soil of humus horizon. Each drainage trench is made with the depth of at least 1.1 m and the width of at least 50 cm across the direction of flow of surface waters at an angle of not more than 30 degrees to the horizontal. The drainage pipe with protective-filtering material is sprinkled with soil of humus horizon, cut off from the upper edges of the trench, not less than 15 cm above the pipe crown. The filtering elements are made in the form of a single block composed of the nodd number (n?3) of the vertical regular prisms parallel to the trench walls, in which the prism of soil of humus horizon alternates with the prism from the excavated soils. The width of the prism from the excavated soil is two times greater than the width of the prism of soil of humus horizon, and the width of the trench B and the width of each odd prism of soil of humus horizon bare related to each other as b=2B/(3n-1).EFFECT: improvement of hydrological action of the closed regulatory network, increase in efficiency of the use of topsoil and the ecological and economic efficiency of drainage of average-loamy soils.2 cl, 5 dwgИзобретение относится к сельскому хозяйству и комплексной мелиорации агроландшафтов и может быть применено в Нечерноземной зоне как при проектировании, строительстве, реконструкции, ремонте и эксплуатации дренажных систем, так и при использовании дренируемых среднесуглинистых почвогрунтов с высоким плодородием и атмосферным водным питанием почвы. Способ включает устройство дренажной траншеи с уложенной на ее дно дренажной трубой с защитно-фильтрующим материалом, фильтрующие элементы в виде призм из почвы гумусового горизонта, устроенные в траншее до пахотного слоя, и
