Özet

Environmental pollution can be minimized with reducing the amount of wastes emerged, harmonizing the wastes with environment and land use of waste materials. Sewage sludge, a by-product of wastewater treatment, can be used as a replacement and/or amendment for natural materials. However, it should be noted that sewage sludge contains heavy metals and soluble salts, which could be toxic to the soil and plants. This study was carried out to determine the effects of different sewage sludge application rates, which were 0, 4, 8 and 12 t da(-1), on yield, yield parameters, and heavy metal uptake of barley grown under arid climatic conditions. The experiment was conducted using a randomized complete block design with three replications in 12 plots, between years 2005-2007. Results obtained from this study have shown that sewage sludge is an effective way to improve yield, yield parameters and metal content of barley under arid climatic conditions. The most effective application rate was found as 12 t da(-1) in this study. However, it should be noted that this situation depends on ecological conditions and species. Further studies should be conducted to evaluate the effects of sewage sludge on other plant species. (C) 2012 Friends Science Publishers
