Alley cropping in the moist savanna of West Africa I. Restoration and maintenance of soil fertility on terre de barre soils in Benin Republic por Aihou, K., Sanginga, N., Vanlauwe, Bernard, Lyasse, O., Diels, J., Merckx, Roel

“…Especially the Senna and to a lesser degree the Leucaena treatment yielded consistently more grain than the control. The Senna trees contained a larger amount of N and produced more wood during the first pruning on the degraded site (155 kg N ha–1 and 14.0 ton fresh wood ha–1) than on the non-degraded site (49 kg N ha–1 and 6.6 ton fresh wood ha–1) most likely because of differences in subsoil fertility, as indicated by the higher clay, exchangeable bases, and N content between 60 and 125 cm cm. …”
