FIELD: agriculture.
SUBSTANCE: invention relates to the biomelioration of degraded agricultural lands. Method includes searches containing soil agro-meliorative surveys of the site, with a complex, scrupulously diagnosed aerial photographs by a laser scanning system and geophysical route ground, non-digging echolocation probing indicators of degraded land condition and with the simultaneous input of the received data to the magnetic carrier into the PC base, mapping the site to GIS, preparing a program for switching it on and off from the control panel and the coordinate system via the GPS receiver of the combined unit with reference to geographic coordinates and transferring the results to the control processor of the combined unit performing sequentially simultaneous processing. Additionally, it is carried out the targeted introduction of ameliorant, at that the soil layer is cut, at the same time loosening the soil and subsoil boundary layers and feeding into this layer ameliorant – iron vitriol, or spent electrolyte, sulfuric acid solution, and in the cavity between the cut and processed with application of the chemical ameliorant to the disconnected lumps, form a 0.02–0.07 m layer of liquid manure. Bulk subsoil loosening is carried out and simultaneously form at the bottom of the loosened under-sun layer the strip waterproof during precipitation and during the drought, the water-regulating organomineral screen, permeable with the roots of plants, with the laying of the organomineral mixture through the cavities of the deep-seated from 0.35 to 0.55 m parabolic racks of voluminous rippers and between them under the dumps of the mixture with its composition, vol. %: plant residues and humus – 33–50, montmorillonite with a microelement of molybdenum – 3–10, mixture of silt, aleurite, sand – 15–40, iron vitriol – 0–15, clay – 15–37. At that the wings are arranged above the screen in the soil layer and grind the soil aggregates, shrubby shoots and create a layer of a mixture of liquid manure, sand, silt and water in the soil layer of the 0.02–0.1 m backstage. Addressable introduce the ameliorant – loose lime on the soil surface, or phosphogypsum, while the water-regulating organomineral screen is laid below the solonetz layer.
EFFECT: method allows to shorten the biomelioration period of degraded lands with the presence of spots of alkaline soil, complexes of solonetzes and subsoil lenses of solonetz, increase the productivity of agricultural lands with rain-fed plant cultivation, while simultaneously desalinizing the soils.
