- 摘要：
FIELD: agriculture.SUBSTANCE: invention relates to techniques of drainage of agricultural land of nonchernozem belt with closed drainage and the techniques of use of these lands. The method comprises loosening the drained soils to a depth of at least 60 m. In order to ensure the required by the plants of soil humidity conditions, preventing the possible damage to the pipes of closed drainage and providing industrial applicability of deep loosening, the deep loosening is carried out to a depth of h, determined in each case from the condition of compliance with the following requirements: (h)? h? (h);(1), h? (h)- D - ??h(2), where ??h= ?h+ ?h+ ?h+ ?h; (3), 60 ? h? h, (4) where (h)and (h)are the minimum and maximum depth of penetration into the trench backfill of the closed drainage of the root system of cultivated culture, respectively, cm; (h)is the minimum depth of placement of closed drainage pipes of the project at the site where deep loosening is planned to be carried out, cm; D is the outer diameter of
