The Effects of Sewage Sludge Applications on Platanus orientalis Species

In this study, the sewage sludge taken from G？kova-Akyaka Wastewater Treatment Plant was used as soil cover materail in Platanus orientalis L. the effect of this material on the plant growth was investigated. The study was established for two years and the cover material applicated once in four months as 20 kg/m2 doses. Research was conducted as 3 replicates and according to random parcels split-split plot design. During the study plant height, body diameter and leaf color criterias were examined. At the end of the first and the second year of the study, some plant nutrient elements and heavy metals were analysed in the leaves. As result of the study P. orientalis species effected positively from sewage sludge and the application doses having any toxic affects. The most suitable dose per year is 60 kg/m2
