The functioning of trees as a safety-net for capturing nutrients leached beyond the reach of crop roots was evaluated by investigating changes in exchangeable cations (Ca, Mg, and K) and pH in a wide range of medium to long term alley cropping trials in the derived savanna of West Africa, compare...

Evaluating options for soil organic carbon maintenance under intensive cropping in the West African savanna using the Rothamsted Carbon (RothC) model
The potential of alley cropping systems supplied with a limited amount of fertilizer to restore crop productivity on a degraded site and to maintain crop productivity on a recently cleared, non-degraded site on ‘terre de barre' soils in Southern Bénin was investigated from 1994 to 1996. Leucaena ...

The impact of land use (unfertilized continuous maize cropping, unfertilized and fertilized alley cropping with maize, Gliricidia sepium tree fallow, natural fallow) on the soil organic matter (SOM) status and general soil fertility characteristics were investigated for a series of soils represen...

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...

Nutrient depletion is a major constraint to crop production for moist savanna soils, and inputs of nutrients are required to overcome this constraint. The impact of sole and combined applications of organic inputs (OIs) [fresh tree prunings, Pueraria phaseoloides (Roxb.) Benth. residues, and manu...
