Our study on soil N dynamics was conducted in the rainy season of 2005 and 2006. It focused on the effects of soil managements with sole and combined applications of mineral and organic fertilizers in the long-term experiment conducted since 1993 in the Niamey Center of the International Crop Res...

In the Fakara region of the Sahel zone, Niger, West Africa, farmers have been implementing traditional soil man-agement practices such as the application of dry farmyard manure (FYM) and household waste (HHW), livestockcorralling, and fallows. Previousstudies, however, have not accumulatedenough ...

Cowpea [Vigna unguiculata (L.) Walp.] plays an important role in the livelihoods of the people of sub-Saharan Africa, but phosphorus (P) deficiency in soils is a serious problem that contributes to low productivity. This study was conducted to verify the efficiency of indigenous rock phosphate (R...

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...
