FIELD: agricultural amelioration, in particular, drainage of surface and underground water from closed lowlands free of outflows and drainage of water-logged soil of fields. ^ SUBSTANCE: method involves creating absorbing wells in lower part of agricultural land relief under arable layer; providing absorbing wells with filtering material and laying back filter thereon; providing mole drainages and ditches around absorbing wells, said drainages and ditches being inclined toward said wells and spilled with layer of back filter; placing plant ground layer onto surface of back filter, said plant ground layer having height sufficient for cultivation of field surface by means of agricultural equipment; using collector communicating absorbing wells with one another for discharge of excessive water. ^ EFFECT: increased efficiency in discharge of excessive water from two or more closed lowlands of agricultural fields and improved ameliorative state of soil. ^ 3 dwg |
