Major upland soils in the humid and sub humid zones of West Africa consist of low activity clays (LAC) Alfisols, Ultisols and Oxisols. Alfisols which are less leached and have a high base saturation are more dominant in the sub-humid zone. Chemically they are more fertile, but they have a low str...

Yields of intercropped oil palm (Elaeis guineensis) and cocoyam (Xanthosoma sagittifolium) were assessed at Okomu (6°25'N, 5°12'E), near Benin City, southern Nigeria. Yields were assessed during the fifth and sixth year after the establishment of oil palm. The annual yield of fresh fruit bunches ...

The recovery of a single application of leucaena (Leucaena leucocephala) leaf N (78 kg N ha−1) in a maize crop, the hedgerow and the top 10 cm soil of a leucaena alley cropping system was measured for 236 d through the use of 15N labeled residues. The leucaena-derived-N (LDN) was followed in the ...
