STUDIES OF THE POSSIBILITY OF USING MUSHROOM WASTE IN BIOREMEDIATION OF AGRICULTURAL SOILS

Abstract

The paper considers the possibilities of using organic substrates after cultivation mycelial cultures of xylotrophic basidiomycetes for bioremediation of soils contaminated with polyphenolic compounds and heavy metals. A 0.9-3-fold decrease in the integral soil toxicity indicator under the influence of mycelial-substrate complexes (mushroom cultivation and biotechnology waste) was shown. The dynamics of the humus content in soil samples as a result of introducing oyster mushrooms (Pleurotus ostreatus) as a fertilizer was studied. It was found that the content of humus in the experimental variants increased by 0.08-0.14%. At the same time, the use of mushroom cultivation waste as fertilizers made it possible to increase the yield of spring wheat “Tulaykovskaya 10” by 10.7-29.5%.
