Adams, Alexis M.Gillespie, Adam W.Dhillon, Gurbir S.Kar, GourangoMinielly, ColinKoala, SaidouOuattara, BadioriKimaro, Anthony A.Bationo, AndreSchoenau, Jeff J.Peak, Derek[Long-term effects of integrated soil fertility management practices on soil chemical properties in the Sahel]Long-term effects of integrated soil fertility management practices on soil chemical properties in the Sahel

Zambia has three primary agro-ecological regions, with each region having specific ecological characteristics. Region II agro-ecological zone of Zambia has low nutrient reserves and poor water holding capacity due to moderately leached clayey to loamy soil; this has led to low soybean productivit...


Alamu, E.O.Gondwe, T.Akinwale, G.Suzuki, K.Chisonga, C.Chigeza, G.Maziya-Dixon, B.B.[Impact of soil fertility management practices on the nutritional quality of Soybean (Glycine max (l.) Merr.) varieties grown in Eastern Zambia]Impact of soil fertility management practices on the nutritional quality of Soybean (Glycine max (l.) Merr.) varieties grown in Eastern Zambia

Load estimates are more informative than constituent concentrations alone, as they allow quantification of on- and off-site impacts of environmental processes concerning pollutants, nutrients and sediment, such as soil fertility loss, reservoir sedimentation and irrigation channel siltation. Whil...


Slaets, J.I.F.Piepho, Hans-PeterSchmitter, Petra S.Hilger, T.Cadisch, Georg[Quantifying uncertainty on sediment loads using bootstrap confidence intervals]Quantifying uncertainty on sediment loads using bootstrap confidence intervals

Soybean is becoming an important cash crop in northern Ghana. Yet the yields are low due to use of low yielding varieties and limited use of inputs. Greenhouse and field experiments were carried out to evaluate the effects of two phosphorus (P) sources and Rhizobium inoculation on growth, nodulat...


Adjei-Nsiah, SamuelKumah, J.F.Owusu-Bennoah, E.Kanampiu, F.[Influence of P sources and rhizobium inoculation on growth and yield of soybean genotypes on Ferric Lixisols of northern Guinea savanna zone of Ghana]Influence of P sources and rhizobium inoculation on growth and yield of soybean genotypes on Ferric Lixisols of northern Guinea savanna zone of Ghana

Agroforestry systems involving leaf removal for animal fodder may result in rapid depletion of soil fertility. The purpose of this research was to determine if the effects of leaf removal on soil fertility parameters and maize yield in aLeucaena leucocephalaalley cropping system could be reversed...


Wendt, J.W.Jones, R.B.Bunderson, W.T.Itimu, A.O.[Leucaena + maize alley cropping in Malawi; part 2: residual P and leaf management effects on maize nutrition and soil properties]Leucaena + maize alley cropping in Malawi; part 2: residual P and leaf management effects on maize nutrition and soil properties

Maintaining indigenous nutrient supply and positive nutrient balances are key factors in sustaining rice yields. Irrigation systems act as conveyers for water, sediments and nutrients throughout landscapes, especially in mountainous, cultivated tropical areas where erosivity is usually high. Cont...


Slaets, J.I.F.Schmitter, Petra S.Hilger, T.Hue, D.T.T.Piepho, Hans-PeterVien, T.D.Cadisch, Georg[Sediment-associated organic carbon and nitrogen inputs from erosion and irrigation to rice fields in a mountainous watershed in Northwest Vietnam]Sediment-associated organic carbon and nitrogen inputs from erosion and irrigation to rice fields in a mountainous watershed in Northwest Vietnam

Composite agricultural systems with permanent maize cultivation in the uplands and irrigated rice in the valleys are very common in mountainous southeast Asia. The soil loss and fertility decline of the upland fields is well documented, but little is known about reallocation of these sediments wi...


Slaets, J.I.F.Schmitter, Petra S.Hilger, T.Vien, T.D.Cadisch, Georg[Sediment trap efficiency of paddy fields at the watershed scale in a mountainous catchment in northwest Vietnam]Sediment trap efficiency of paddy fields at the watershed scale in a mountainous catchment in northwest Vietnam

Agricultural extension to improve yields of staple food crops and close the yield gap in Sub-Saharan Africa often entails general recommendations on soil fertility management that are distributed to farmers in a large growing area. Site-specific extension recommendations that are better tailored ...


Oyinbo, O.Chamberlin, JordanVanlauwe, BernardVranken, L.Kamara, A.Craufurd, Peter Q.Maertens, M.[Farmers' preferences for high-input agriculture supported by site-specific extension services: evidence from a choice experiment in Nigeria]Farmers' preferences for high-input agriculture supported by site-specific extension services: evidence from a choice experiment in Nigeria

Nutrient limitation is a major constraint in crop production in sub-Saharan Africa (SSA). Here, we propose a generic and simple equilibrium model to estimate minimum input requirements of nitrogen, phosphorus and potassium for target yields in cereal crops under highly efficient management. The m...
