Sandy deposols, type of anthropogenic soils, become after coal mine tailing as a consequence of storage of surface layers which was over the coal. Quantity of excavated soil is huge (3,5m3 deposols per tone of coal). Nowdays, surfaces which is covered with deposol of power plant Kostolac (Serbia), are near to 4000ha, but increasing every year (over 50ha per year). Previous research on this deposol noticed increased accumulation of nickel and chromium in each plant organ after planting annual plant on sandy deposol during the recultivation of them [1] . Concentration of heavy metals in deposol was under the maximum allowed concentration but their uptake by annual plant was considerable. In this study, different amendments were added as a source of nutrients and also to immobilize heavy metals. Zeolite and monoammonium phosphate were used to stabilize heavy metals. Experiment was performed on grapevine. But it was adverse effect. With increasing doses of phosphate, concentration of nickel increased. Chromium is present in each treatment but it was not dependant on treatment.
