Abstract
Phyto-remediation by kenaf was attemptedto apply to improve eutrophic water quality. The growth of kenaf was satisfactorily achieved in water environment by using Kanuma-soil(sedimentary rocks and clays of volcanic ashes obtained primarily in northern region of Kanto Plain in Japan). Nitrate was removed from eutrophic water through growing kenaf, while phosphate was mainly absorbed on Kanuma-soil. Accordingly, the combination of kenaf and Kanuma-soil was found to be effective for remediation of eutrophic water environment.
