Аннотация:The effect of potassium humates and biochar on the stabilization of heavy metals in the soil and their uptake by plants was investigated in a short-term field experiments on remediation of industrial barrens near the mining-metallurgical complex «Severonickel». The application of potassium humates (1 %) reduces the content of heavy metals in the roots and shoots of Festuca rubra. The application of biochar (0.5 and 1 %) improves plant nutri-tion, but does not significantly affect the concentrations of Ni and Cu. The use of biochar requires further research.
