Vanlauwe, BernardSix, JohanSanginga, NteranyaAdesina, A.A.[Soil fertility decline at the base of rural poverty in sub-Saharan Africa]Soil fertility decline at the base of rural poverty in sub-Saharan Africa

It has been repeatedly argued that mineral fertiliser application combined with in situ retention of crop residue biomass can sustain long-term productivity of West African soils. Using 20-year experimental data from southern Togo, a biannual rainfall area, we analysed the effect of two rates of ...


Kintché, K.Guibert, H.Sogbedji, J.M.Levêque, J.Bonfoh, BassirouTittonell, Pablo A.[Long-term mineral fertiliser use and maize residue incorporation do not compensate for carbon and nutrient losses from a Ferralsol under continuous maize-cotton cropping]Long-term mineral fertiliser use and maize residue incorporation do not compensate for carbon and nutrient losses from a Ferralsol under continuous maize-cotton cropping

tCoffee is Uganda’s biggest export commodity, produced mainly by an estimated one million smallholderfarmers (<2.5 ha). Arabica (Coffea arabica L.) and Robusta (Coffea canephora Pierre ex Froehn.) are thetwo coffee species grown. Robusta is dominantly cultivated at lower elevations (<1400 m) such...

A better understanding of the factors that contribute to low cassava yields in farmers’ fields is required to guide the formulation of cassava intensification programs. Using a boundary line approach, we analysed the contribution of soil fertility, pest and disease infestation and farmers’ cultiv...

Nutrient flux and balance studies are valuable tools to assess the sustainability of agro-ecosystems and potential consequences for agricultural productivity. This paper presents results from a study at the field/farm scale representing mixed farming systems typical for the East African Highlands...

Soils used for rainfed cereal production in Niger are sandy, deficient in major nutrients (N and P), and also low in organic matter content. Scarce rainfall with an unpredictable distribution in space and time makes crop and nutrient management difficult. Observations were made in 1996 and 1997...

Balances between nutrients applied or mineralized and nutrients removed in maize grain and stover were calculated in a hedgerow intercropping experiment in which Leucaena leucocephala and L. pallida prunings and cattle manure were applied. Hedgerow intercropping (also called alley cropping) is an...

Ecological restoration through exclosure establishment has become an increasingly important approach to reversing degraded ecosystems in rangelands worldwide. The present study was conducted in northwestern Ethiopia where policy programs are aiming to restore degraded lands. Changes in soil prope...
