Knowledge of soil spatial variability is important in natural resource management, interpolation and soil sampling design, but requires a considerable amount of geo-referenced data. In this study, mid-infrared spectroscopy in combination with spatial analyses tools is being proposed to facilitate...


Cobo Borrero, Juan G.Dercon, G.Yekeye, TChapungu, LKadzere, CMurwira, ADelve, Robert J.Cadisch, Georg[Integration of mid-infrared spectroscopy and geostatistics in the assessment of soil spatial variability at landscape level]Integration of mid-infrared spectroscopy and geostatistics in the assessment of soil spatial variability at landscape level

The soil organic carbon (SOC) dynamic is a key element of soil fertility in savannah ecosystems that form the key agricultural lands in sub-Saharan Africa. In the western part of Burkina Faso, the land use is mostly linked to cotton-based cropping systems. Use of mechanization, pesticides, and he...


Ouattara, BOuattara, K.Serpantie, G.Mando, ASedogo, MPBationo, B. André[Intensity cultivation induced effect on soil organic carbon dynamic in the western cotton area of Burkuna Faso]Intensity cultivation induced effect on soil organic carbon dynamic in the western cotton area of Burkuna Faso

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...


Vanlauwe, BernardAihou, K.Aman, SIwuafor, E.N.O.Tossah, B.K.Diels, J.Sanginga, NteranyaLyasse, O.Merckx, R.Deckers, J.[Maize yield as affected by organic inputs and urea in the West African moist savanna]Maize yield as affected by organic inputs and urea in the West African moist savanna

Organic resources (ORs) are essential inputs in tropical farming systems and their decomposition dynamics are related to their quality. A Decision Support System (DSS) for organic N management has been proposed earlier that subdivides ORs in four classes depending on their N, lignin, and soluble ...


Vanlauwe, BernardGachengo, CNShepherd, Keith D.Barrios, E.Cadisch, GeorgPalm, C.A.[Laboratory validation of a resource quality-based conceptual framework for organic matter management]Laboratory validation of a resource quality-based conceptual framework for organic matter management

Traditional farming systems in Sub-Saharan Africa depend primarily on mining soil nutrients. The African green revolution aims to intensify agriculture through the dissemination of integrated soil fertility management (ISFM). This paper develops a robust and operational definition of ISFM based o...

Erosion trials under natural rainfall were conducted at two locations in the Andean hillsides of south-west Colombia on moderate slopes. Sediment-bound losses of seven cassava (Manihot esculenta) cropping systems per cropping period ranged from 26 to 1726 kg ha?1 for organic matter, 0.9 to 65.5 k...


Ruppenthal, MLeihner, D.E.Steinmuller, N.El-Sharkawy, Mabrouk A.[Losses of organic matter and nutrient by water erosion in cassava-based cropping systems]Losses of organic matter and nutrient by water erosion in cassava-based cropping systems

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...

Soil mineral deficiencies or toxicities adversely affect common bean (Phaseolus vulgaris L.) production worldwide. Cultivars tolerant to low soil fertility (LF) should support sustainable farming systems and reduce production costs and farmers' dependence on fertilizers. Our objective was to iden...
