CONSERVING OF THE RESOURCES
Assisted phytostabilization of a heavy metals contaminated soil using mineral amendments and L. perenne
Pressures exerted on the soil ecosystem due to its exposure to Zn evoke a real and aggravating effect on the quality of life. Greenhouse pot experiments were conducted to study the effects of mineral amendments (zeolite and bentonite) on selected physico-chemical properties of soil, L. perenne growth, Zn accumulation in plant and soil. The contents of Zn in the plants and soil were determined using the method of spectrophotometry. Zn contents in the tested parts of L. perenne differed significantly in the case of applying amendments to the soil, as well as increasing concentrations of Zn. The greatest average above-ground biomass was observed when zeolite were amended into the soil. Bentonite also caused significant increases in Zn concentrations in the roots. Bentonite and zeolite were shown to be the most effective and decreased the average Zn contents in soil.
