The study focuses on the the experimental test of reforestation with Maesopsis eminii and Millettia drastica in the eco-climatic conditions of Kinshasa, with the aim of assessing the development and growth of the species through germination, and their behaviour in relation to the soil in the conditions of Kinshasa, with a view to proposing advice for responsible afforestation and reforestation. The results show that both species tend to reduce soil acidity. After cultivation, the pHs were 4.49 and 4.69 respectively for soils 1 and 2, compared with 3.98 for soil 0. In addition, Millettia drastica neutralises aluminium in the soil (reducing edaphic toxicity). As Al has a high valency, it prevents the adsorption of other cations, increasing soil toxicity. Millettia drastica is a slow-growing species, while Maesopsis eminii is fast-growing. The combination of Millettia drastica and Maesopsis eminii helps to improve degraded soils.
