Nziguheba, GeneroseZingore, ShamieKihara, JobMerckx, R.Njoroge, S.Otinga, A.Vandamme, E.Vanlauwe, Bernard[Phosphorus in smallholder farming systems of subSaharan Africa: implications for agricultural intensification]Phosphorus in smallholder farming systems of subSaharan Africa: implications for agricultural intensification

Smallholder farmers in East-Africa commonly intercrop maize (Zea mays L.) with grain legumes to maximize utilisation of land and labour, and attain larger crop yields. Conventionally, one legume line is intercropped between each pair of maize lines. This study evaluated the potential of a modifie...


Mucheru-Muna, M.Pypers, PieterMugendi, DNKung'u, J.B.Mugwe, JMerckx, R.Vanlauwe, Bernard[A staggered maize-legume intercrop arrangement robustly increases crop yields and economic returns in the highlands of Central Kenya]A staggered maize-legume intercrop arrangement robustly increases crop yields and economic returns in the highlands of Central Kenya

A large proportion of total P in the soils of the area is unavailable to plants and consequently P is the second most limiting nutrient. The labile and moderately labile phosphorus fractions and adsorption characteristics of surface and subsurface horizons of eleven soil profiles in the derived s...


Nwoke, O.C.Vanlauwe, BernardDiels, J.Sanginga, N.Osonubi, O.Merckx, R.[Assessment of labile phosphorus fractions and adsorption characteristics in relation to soil properties of West African savanna soils]Assessment of labile phosphorus fractions and adsorption characteristics in relation to soil properties of West African savanna soils

Lowland rice production in sub-Saharan Africa (SSA) is often limited by water supply and low phosphorus (P) availability and efforts are needed towards more efficient management of both resources. Field and pot experiments were set up to evaluate combinations of water saving technologies and micr...


Bauw, P. deVandamme, E.Senthilkumar, K.Lupembe, A.Smolders, E.Merckx, R.[Combining phosphorus placement and water saving technologies enhances rice production in phosphorus-deficient lowlands]Combining phosphorus placement and water saving technologies enhances rice production in phosphorus-deficient lowlands

Scanty information on long-term soil organic carbon (SOC) dynamics hampers validation of SOC models in the tropics. We observed SOC content changes in a 16-year continuously cropped agroforestry experiment in Ibadan, south-western Nigeria. SOC levels declined in all treatments. The decline was mo...


Diels, J.Vanlauwe, BernardMeersch, M.K. van derSanginga, N.Merckx, R.[Longterm soil organic carbon dynamics in a subhumid tropical climate: 13C data in mixed C3/C4 cropping and modeling with ROTHC]Longterm soil organic carbon dynamics in a subhumid tropical climate: 13C data in mixed C3/C4 cropping and modeling with ROTHC
Vandeplas, IDriessens, LVanlauwe, BernardMerckx, R.Deckers, J.[Bringing soybean production closer to farmer´s reality: alternative options for inputs and labour]Bringing soybean production closer to farmer´s reality: alternative options for inputs and labour

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...


Vanlauwe, BernardAihou, K.Tossah, B.Diels, J.Sanginga, NteranyaMerckx, R.[Senna siamea trees recycle Ca from a Carich subsoil and increase the topsoil pH in agroforestry systems in the West African derived savanna zone]Senna siamea trees recycle Ca from a Carich subsoil and increase the topsoil pH in agroforestry systems in the West African derived savanna zone

Crop response, tree biomass production and changes in soil fertility characteristics were monitored in a long-term (1986–2002) alley-cropping trial in Ibadan, Nigeria. The systems included two alley cropping systems with Leucaena leucocephala and Senna siamea on the one hand and a control (no-tre...

Diels, J.Aihou, K.Iwuafor, E.Merckx, R.Vanlauwe, Bernard[Evaluating options for soil organic carbon maintenance under intensive cropping in the West African savanna using the Rothamsted Carbon (RothC) model]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 ...
