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 the closed drainage pipes at the site (cm) ??his the sum of corrections (cm), including: the correction which depends on the accuracy of the topographic altitude survey of soil surface of the drained site, ?h the corrections taking into account the technogenic erosion of the soil surface during carrying out crop-engineering and land planning ?hand during ploughing ?h correction taking into account the depth of the gauge made by the tractor on the soil surface during deep loosening, ?h his the maximum possible depth of loosening soil due of the technology level and characterising the industrial feasibility of the inventive method at that in each point of the drainage trench the thickness of the powdering layer of the drainage pipe over the bottom of the trench m> h- h, where his the depth of placement of the closed drainage pipe. Prior to loosening the soil on the drained part the value of the set depth of deep loosening is set on the mechanism of the ripper when setti
