This work wants to point out the beneficial effects of the tree Leucaena leucocephala in Organic Agriculture. This specie was introduced at the experimental farm of St. Joseph Vocational Centre in Lunsar, Sierra Leone, in 1987. Until 1989 data were collected and observations made to evaluate the performances of this outstanding tropical tree. Due to its rapid growth, within the first year of trial many positive effects were noted, especially for the protection of sloping soils from water erosion. Trying to minimize soil erosion was in fact the main purpose for planting these trees. By the end of the third year, a remarkable yield increase was also obtained in maize, peanut and sweet potato crops. These were cultivated organically in rotation on the alleys of land among the tree hedges. More successful, practical uses of Leucaena will be described in this paper.
