摘要

Poor productivity of food crops due to low soil nutrientlevels is a major contributor to food insecurity in sub-Saharan Africa (SSA) (Shapouri et al., 2010). Currentinvestments to help farmers increase fertilizer use are not oftensupported by appropriate fertilizer recommendations (Gilleret al., 2011), resulting in poor fertilizer use effi ciency and loweconomic returns to investment in fertilizer (Nziguheba et al.,2009). Information that can help to target the right fertilizersource and application rates for specifi c crops and locations,is crucial for sustainable crop production intensifi cation insmallholder farming systems
