영문 초록

In order to utilize a water supply plant sludge (WSPS) as a potting medium amendment, growth and mineral uptake in Hedera helix (ivy) were investigated after plants were grown for 60 and 90 days in potting media consisting of peatmoss, perlite, and WSPS with different mixing ratios. Though organic contents of media treated with WSPS were higher than those of control before planting, the concentrations of available phosphate were lower in media treated with WSPS. The facts that any treatment treated with WSPS was higher in nitrate nitrogen (NO₃-N) than control indicate WSPS may be utilized as a fertilizer with potential nitrogen source. At 90 days after treatment, differences of the plant height, number of leaves and fresh weight of shoot were not significant among treatments. However, the number of branches with WSPS showed higher value of 2.0 than control of 1.5. Contents of trace elements, such as Fe and Mn, were higher in ivy grown in media with WSPS than control. Especially, Fe contents were 10 times higher in shoots than in roots. In all the treatments, Cd was not detected in ivy. Although Pb was detected in the treatments with sludge, but detected content of Pb was negligible amount. In conclusion, WSPS may be used as a potting medium amendment for ivy.
