“the eco-village organically fertilises soil through the planting and pruning of nitrogen-fixing trees planted on farms where mixed cropping is practised. When the trees mature, the middles are cut out and the leaves used as compost. The trees are then left to regenerate and the same procedure is repeated the following season.” Mbom Sixtus describes here how the principles of permaculture, including the use of fertiliser trees, have been adapted in a Cameroonian village.
