Organic 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...

Cocoa cultivation is generally considered to foster deforestation. Contrary to this view, in the forest–savannah interface area in Cameroon, farmers have planted cocoa agroforestry systems on Imperata cylindrica grasslands, a soil-climate zone generally considered unsuitable for cocoa cultivation. We undertook a survey to understand the agricultural and ecological bases of...

These principles can be applied using various practices and strategies, each having different effects on productivity, stability...
