COMPOSITION AND METHOD FOR APPLICATION OF RENATURATION MIXTURES Russian patent published in 2022 - IPC C05F7/00 A01B79/02 C04B18/30 

FIELD: ecological rehabilitation.

SUBSTANCE: inventions group relates to the ecological rehabilitation of lands disturbed by open-pit mining. The composition of the renaturation mixture containing a hay-seed mixture of background phytocenotic groups and an organomineral mixture, while the organomineral mixture contains loamy soils potentially suitable for biological reclamation as a mineral filler in the form of loess-like loams and an organic filler, namely, fermented organic waste, such as municipal waste wastewater or fermented sludge from filtration fields of industrial organic wastewater, calculation of the ratio of the components of the organic-mineral mixture depending on the amount of mineral filler according to the formula

where is the mass of the mineral filler, kg; – content of organic matter in the mineral filler, %; - conversion factor for dry matter of mineral filler; – content of organic matter in fermented organic waste, %; – conversion factor for dry matter in fermented organic waste; coefficient 2 is the empirically determined amount of organic matter in the substrate, which ensures the maximum rate of humus accumulation. The method for using the renaturation mixture includes preparing an organo-mineral mixture by manually or mechanically mixing loamy soil as a mineral filler and fermented organic waste, applying the specified organo-mineral mixture to the surface of a technogenic disturbance manually or mechanically with a layer thickness of 5-6 cm. After that, pre-prepared hay is applied pre-seed mixture harvested in the background communities, the lithological type of which corresponds to the area of man-made disturbance on the donor site, followed by mulching of the exposed layer.

EFFECT: inventions provide ecologically effective rehabilitation of technogenic disturbances by stimulating natural overgrowth and soil cover formation with simultaneous disposal of organic waste.
