FIELD: agriculture.

SUBSTANCE: invention refers to agriculture, in particular, to land reclamation. The method includes deep tillage of soil with soil cultivating tools with passive actuators, rotor-milling treatment of internal soil layers, which is carried out 2-5 years after deep tillage of soil with soil cultivating tools with passive actuators. Soil treatment is carried out in cycles, cycle components include deep tillage of soil with a soil-cultivating tool with passive actuators for depth of 45-50 cm with a pitch of vertical plane circumscribed by the treatment tool in the space of soil continuum, multiple to minimum distance between lines of plants of future agrophytocenosis, for instance, 45 cm, 70 cm, 110 cm. After deep tillage of soil with a soil-cultivating tool with passive actuators in 2-5 years rotor-milling treatment is carried out for internal soil layers in the discrete zone of soil continuum in the layer of 25-50 cm. The width of the treated space of the soil continuum, for instance, 15 cm, 23 cm, 34 cm, is selected so that it makes not more than 1/3 of the distance between lines of deep tillage. The discrete zone of rotor-milling treatment of internal soil layers is placed in the soil continuum symmetrically so that the vertical axis of its symmetry matches the axial plane of symmetry of the vertical discrete zone of the soil continuum, previously arranged in the space of the soil continuum with a treatment tool of the soil-cultivating tool with passive actuators. In 20-30 years the cycle is repeated by means of the specified sequence of soil treatments. Treatment is carried out with displacement in the vertical plane circumscribed with the treatment tool of the soil-cultivating tool with passive actuators in the space of soil continuum by 1/3 of the distance between tillage lines selected when performing the first cycle of soil treatment. Cycles of soil treatment by the soil continuum are closed in 60-90 years and are continued in the same manner.

EFFECT: method makes it possible to stabilise soil profile and a biogeosystem as a whole, to improve quality of soil tillage, to provide for long-term soil reclamation effect and to optimise conditions for development of plant rhizosphere.
