Nutrient additions to intensive agricultural systems range from inadequate excessive—and both extremes have substantial human and environmental costs.
Abstract. Intensification of smallholder agriculture in sub-Saharan Africa is necessary to address rural poverty and natural resource degradation. Integrated soil fertility management (ISFM) a means enhance crop productivity while maximizing the agronomic efficiency (AE) applied inputs, can thus contribute sustainable intensification. ISFM consists set best practices, preferably used combination, including use appropriate germplasm, fertilizer organic resources, good practices. The large...
Improved understanding of soil fertility factors limiting crop productivity is important to develop appropriate and nutrient management recommendations in sub-Saharan Africa. Diagnostic trials were implemented Kenya, Malawi, Mali, Nigeria Tanzania, as part the African Soils Information Service (AfSIS) project, identify constraints production across various cropping systems conditions. In each country, one three sites 10 km × included with site having 12–31 field trials. The treatments tested...

A Scientific Committee on Problems of the Environment Rapid Assessment (SCOPE-RAP) workshop was held 18–22 March 2013. This hosted by European Commission, JRC Centre at Ispra, Italy, and brought together 40 leading experts from Africa, Asia, Europe North South America to create four synthesis chapters aimed identifying knowledge gaps, research requirements, policy innovations. Given forthcoming publication CABI a book volume outcomes SCOPE-RAP in 2014, this report provides an update global...
Low and declining soil fertility has been recognized for a long time as major impediment to intensifying agriculture in sub-Saharan Africa (SSA). Consequently, from the inception of international agricultural research, centres operating SSA have had research programme focusing on management, including International Institute Tropical Agriculture (IITA). The scope, content, approaches management changed over past decades response lessons learnt internal external drivers this paper uses IITA...
Abstract Low nutrient use efficiency in maize as a result of imbalanced nutrition has been reported to drastically reduce yield. We implemented omission experiment assess the effect application on yield and nutritional balance. Maize ear leaves were analyzed for nutrients, identify balance status using Diagnostic Recommendation Integrated System (DRIS) approach. Results indicated that N or P resulted highly DRIS indices respectively, significantly lower grain A strong inverse relationship...
