To produce charcoal and prevent deforestation around Kinshasa, 7,700 ha of Acacia auriculiformis were planted on savannah ecosystems in 1987 (Bateke Plateau). Since 1995, the plantation was managed using the rotational woodlot system alternating agricultural and charcoal production on the same area (Kimaro et al., 2007). Since 2005, the burning of residues was used to activate the germination of acacia seeds after carbonization. The objective of the study was to analyze the long term effect of rotational woodlots with N2 -fixing trees on soil chemical fertility.
