The paper discusses the possibilities of the practical use of organic substrates after cultivation of fungi - basidiomycetes on them. The waste resulting from the cultivation of mushrooms is rich in nutrients and can be recycled as soil fertilizer and can also contribute to the remediation of polluted soils. The composition of the mycelial-substrate complex of the oyster fungus (Pleurotus ostreatus), in addition to the enzymatically active mycelium that absorbs pollutants, includes the mass of straw, which also contains nutrients and is able to improve the structure of the soil and increase its fertility. Straw material contains about 95% of organic matter. The dynamics of the humus content in soil samples was studied as a result of the introduction of P. ostreatus fungus production waste as a fertilizer. The use of fungus waste allows maintaining and slightly increasing (by 0.08–0.14%) the humus content in the soil. It also increases the yield of spring wheat to 29.5%.
