Abstract: Edamame soybeans are a type of soybean that originates from Japan and has been cultivated in Indonesia. The purpose of this study was to determine the effect of LOF of golden apple snails and oil palm bunch ash on edamame soybean yields and C-Organic content in Inceptisols. The research method used a factorial randomized block design repeated three times. The first factor was Golden snail LOF (K) which was arranged in four levels, namely 0 mL/polybag (K0), 100 mL/polybag (K1), 200 mL/polybag (K2), and 300 mL/polybag (K3). The second factor was oil palm bunch ash (A) which was arranged in four levels, namely 0 g/polybag (A0), 50 g/polybag (A1), 100 g/polybag (A2), and 150 g/polybag (A2). The results of the study showed that feeding with LOF golden snails and oil palm bunch ash can increase the growth and yield of edamame soybean plants as well as the organic C content of inceptisol soil.
