Kenaf is a member of the Malvaceae family and is cultivated as an annual fiber crop. Recently, kenaf became to be used as teaching materials for environmental education. The stalk of kenaf consists of a bast and a core. Kenaf paper is usually made from stalk bast fiber, and a stalk core is hardly used because of the difficulty of making fiber. In this study, we evaluated the stalk core as soil conditioner and tried to use a kenaf stalk core as teaching materials for agricultural education and environmental education.
