Abstract

Abstract: This study analyzed the effect of heavy metal eluents (0.3 mol/L C6 H8 O7, 5 × 10 −4 mol/L EDTA, and 0.01 mol/L Na2 S2 O3 ) on the content of organic matter, hydrolytic nitrogen, available phosphorus and potassium, and species composition of bacteria and fungi in vegetable soils. The obtained results documented that the treatment of the soil, consisting of shaking the sample with a mixture of eluents, significantly increased the content of organic matter, hydrolytic nitrogen, and available phosphorus and potassium. The mixed solutions of eluents increase the maximum available P in the soil by 279.3%, and hydrolytic N by 30.7%. The eluents affected, to a certain extent, the dominant species of microorganisms in the soil, but did not increase species richness and evenness in all soil samples. Graphical abstract: Image 1 Highlights: The treatment of soils with the mixture of eluents can increase soil fertility. The eluents can affect, to a certain extent, the dominant species of microorganisms in the soil. The eluents can affect the microbial diversity. Abstract : The mixed solutions of heavy metal eluents can enhance the fertility and affect the dominant species of microorganisms in the soil.
