Abstract

Purpose. Study of the possibility of using burned waste from slagheaps and bottom silty deposits of reservoirs as the main ingredients of organo-mineral fertilizer, due to determination of fertility indicators of soil treated with waste. Methodology. On the basis of laboratory studies of the potential fertility of the soil environment and studies of the dynamics of plant germination on experimental soils, the physical and chemical properties of the ingredients of the organo-mineral fertilizer have been determined. Results. As a result of the laboratory studies, it has been found that the addition of burned waste material from slagheaps and bottom silty deposits of reservoirs to the substrate enriched with the products of the processing of Californian earthworms does not reduce the fertility indicators of the substrate. The addition of such admixtures to soils with low and medium indicators of potential fertility will increase their productivity. Scientific novelty. A new composition of ecologically safe organic-mineral fertilizer based on burnt solid mine waste, bottom muddy sediments of reservoirs with the addition of chernozem treated with red California earthworms has been suggested. Practical significance. The use of burned waste mass from slagheaps and bottom silty deposits of reservoirs for the production of cheap composite organo-mineral fertilizers will reduce the anthropogenic load on the environment from mine wastes, increase the content of humus and improve the structure of agricultural soils.
