DOIAbstract
International audienceOrganic fertilizers improve soil fertility in oil palm plantations, based on small-scale (<30 ha), short-term (3-5 yr) studies, but the response is not equal across soil classes. Since organic fertilizers are costly to handle and apply, relative to mineral fertilizers, producers need to know where and how frequently to apply organic fertilizers to improve soil fertility. This study assessed the soil response to long-term mineral and organic fertilizer applications in an industrial oil palm plantation. A landscape-scale approach was developed to cope with unavailable historical soil data, variability in fertilizer application sequences and diverse soil classes across the plantation. Soil response to fertilizer applicati...
