Environmental contaminants such as heavy metals are a major problem for living organisms. Phytoremediation methods are used to eliminate the problem of soil pollution, which is the direct use of living green plants for cleaning the soil. In Georgia, the soil contamination problem is particularly acute in some regions, including Bolnisi Municipality (South-East Georgia the country), where gold and copper are mined in the open-pits. Within the scope of the research, the sugar beet was studied in the field conditions near the mining area using Bio-stimulants Bioragi and Deposit that were not used before. ANOVA statistical method was used for data analysis and accumulation coefficient (AC) was calculated. The study showed that the Cd, Cu, and Zn accumulation coefficients were higher in the control sugar beet than in the plants fertilized with bio-stimulants. The cadmium AC in sugar beet was much higher than copper and zinc AC. In September the sugar beet accumulated the highest concentration of Cd, Cu, and Zn, then in July and October. Control sugar beet uptake more heavy metals in July and September, compared to Bioragi and Deposit, but in October Cd, Cu, and Zn concentrations were higher in sugar beet with Bioragi. It was discovered that the lifespan of the sugar beet with Bioragi was longer than control sugar beet. Bio-stimulants in polluted soils can be appropriate, in terms of reducing heavy metals and have a practical use for agricultural purposes.
