Effects of Sewage Sludge Applications on Plant Growth of Liquidambar orientalis Species
(Univ Namik Kemal, 2018) Cetinkale Demirkan, Gulbin; Sogut, Zerrin
In this research, it was aimed to determine the effects of usage taken sewage sludge from Gokova-Akyaka Wastewater Treatment Plant on plant growth of Liquidambar orientalis species. In the experiment, sewage sludge was applied as 20 kg m(2) year(-1) dose and totally 12 times once in four months during two years (0 kg m(2) year(-1), 20 kg m(2) year(-1), 40 kg m(2) year(-1), 60 kg m(2) year(-1)). For this reason plant height, body diameter, leaf color, some plant nutrients and heavy metals analyses were done. As a result of two year application, the highest length of plant obtained on the plants in a year which sewage sludge applied 20 kg m(2) year(-1), the most thickening on body diameter of the plants applied 40 kg m(2) year(-1), the darkest leaf color of the plants applied 60 kg m(2) year(-1). As a result of analysis, it wass determined that nickel and lead have toxic values. When the results are determined; it was found out that it was suitable to use up to 20 kg m(2) year(-1) sewage sludge on L. orientalis and it did not cause any harm on this species.
