FIELD: revegetation; environmental protection.
SUBSTANCE: invention relates to reclamation and environmental protection, restoration of disturbed land resources, agriculture and can be used to produce soils intended for landscaping and growing herbaceous vegetation in conditions of closed or open ground. Technogenic soil contains soil and biocompost, which is a fermented mixture of transitional peat with a degree of decomposition of not more than 25 % and sludge of biological treatment facilities of household and mixed waste water, dehydrated to 80 %. Sandy soil is used as soil, and biocompost additionally contains fodder wastes, sawdust of natural pure wood with fraction size of 0.5–2.0 cm, soil wastes during open excavation, with the following ratio of components, wt. %: sandy soil – 80–40, biocompost – 20–60, in composition: sludge of biological treatment facilities of household and mixed waste water, dehydrated to 80 % – 31–33, sawdust of natural pure wood with fraction size of 0.5-2.0 cm – 34–35, transitional peat with decomposition degree of not more than 25 % – 12–14, soil wastes during open excavation – 13–15, fodder wastes – the rest.
EFFECT: invention enables to obtain technogenic soil for landscaping and growing herbaceous vegetation.
