- Abstract
The more intensive growth of agricultural crops adding mineral fertilizers, environmental pollution make the soil degraded: reduce the fertility of soil, increase the concentration of heavy metals. Especially dangerous is a common, synergistic effect of heavy metals. Vermicompost optimizes pH, texture and organic material content - the soil indicators, which are the major contributors to migration of heavy metals in the soil and to the plants from it. In the article there is an investigation of vermicompost influence on bioaccumulation of heavy metals in common meadow- grass. After experimental research it is determined that immobilization of heavy metals was the best in soil-vermicompost substrate, prepared in a ratio 1:2. The cadmium (Cd) concentrations were lowest and the difference of HM content determined between roots and shoots was the most in biomass grown up in that mixture. In the underground part of plant the concentration equal to 11.10 mg/kg and in the part of above ground - 1.05 mg/kg. The situation of lead (Pb) and copper (Cu) is analogous. This is the optimal ratio of mixture preparation.
