Reclamation of flotation wastes of Ke？iborlu sulphur factory and phytoremediation with Festuca arundinacea grass

In this study, calcareous soil (10-20-30-40%) and farmyard manure (4-8%) as amendment materials were applied to flotation waste for revegetation of abandoned tailings pools in around Ke？iborlu sulphur factory. As the experimental plant Festuca arundinacea was grown. In this purpose; pot (6 kg) experiment carried out according to the completely randomized design factorial with 4 replicates and 10 different applications. All treatments were equally watered during 12 weeks. After experimental set up for 12 weeks, the samples of media and plant were taken for analysis. pH, electrical conductivity (EC), DTPA-extractable iron (Fe), zinc (Zn), manganese (Mn), copper (Cu), nickel (Ni), chromium (Cr), lead (Pb), cadmium (Cd) and cobalt (Co) concentrations of growing media, also, total Fe, Zn, Mn, Cu, Ni, Cr, Pb, Cd, Co concentrations of plants were analyzed together with the dry weight yield of the plant which were determined at end of the experiment. Increasing ratios of calcareous soil and farmyard manure into flotation waste were raised the dry material weight in grass plants and the highest result of the media were reached at the application of the highest farmyard manure (8%). According to plant analysis results; the highest concentration of Fe and Cu were obtained from 72% FW + 20% CS + 8% FYM application; while Zn, Mn and Pb concentration were obtained from 82% FW + 10% CS + 8% FYM application. According to the media analysis results; the highest concentration of Zn, Cu, Pb and Cd were determined in 62% FW + 30% CS + 8% FYM application; while Fe and Mn concentration were determined in 72% FW + 20% CS + 8% FYM application. However this work indicates that heavy metal concentrations increased CS with FYM more than CS-alone in media
