Although the West-African moist savanna zone has a high potential for crop production, yields on farmers' fields are, on average, far below this potential, mainly due to the low use of external sources of nutrients. Since the mid-1990s, it has become clear that in order to upgrade crop production...

Result of long time alley cropping trials show that the inclusion of N2- fixing hedgerow species maintain higher levels of soil fertility than control treatment (no hedgerow) on high base status soils in the humid zone. Hedgerows contribute to nutrient cycling and higher faunal activity. With goo...
