Abstract: One of the modern environmental problems is the pollution of industrial lands, including with mineral salts. The causes of soil salinization can be both natural and anthropogenic. In any case, an important task is not only the removal of mineral compounds from the soil, but also the recreation of an abiotic environment suitable for the normalization of biological processes. Objects with a high content of mineral salts that require reclamation also include the territories of drained sludge collectors of a waste product of soda production. This article proposes a technology for the comprehensive reclamation of highly mineralized soils, consisting of technical and biological stages. The first stage includes agrotechnical measures aimed at preparing the soil and creating conditions favorable for the further growth of plant communities, in particular, the delivery of clean soil and mixing with the original environment in an experimentally determined ratio, and the introduction of necessary fertilizers. A necessary condition in some cases is the isolation of the restored area to avoid surface leaching of salts with rainwater from nearby areas. The biological stage includes sowing seeds of specially selected species of higher vegetation. It is proposed to use such plant species as Amaranthus paniculatus, Bromopsis inermis, Onobrychis viciifolia, Avena sativa and Triticum aestivum. These species are unpretentious, help restore the balance of soil nutrients by saturating it with nitrogen, provide salt absorption, strengthen the soil, prevent the washout of the enriched surface layer, while forming a dense grass stand. In general, the proposed technology allows for gradual desalination of soils and effective restoration of disturbed ecosystems. It is applicable in the territories of industrial facilities and natural salt marshes.
