Field data have suggested that under P-deficient conditions, legumes supplied with phosphate rock (PR) increase P acquisition by a subsequent maize crop compared to direct application of PR to maize. This study assessed the mechanism of this positive rotational effect in terms of soil P availabil...

Data from the derived savanna zone in southern Benin indicated that some intensive cropping systems (maize/Cajanus and maize/Mucuna relays; maize/cotton with Senna siamea hedgerows) returned about 12 Mg DM ha-1 year-1 of plant biomass to the soil. This compared favorably with the 8 Mg DM ha-1 yea...
