Variable Soils, Variable Fertilizer Quality, and Variable Prospects

Research output: Contribution to journalArticlepeer-review


This article argues for research and policy emphasis on two often-ignored factors critical to increasing regional agricultural productivity in Sub-Saharan Africa: the presence of agronomically and economically important variability in farmer soils; and the capacity of existing agricultural input supply chains in the region to provide the types, quantities, and quality of agricultural inputs that farmers will need to increase yields and respond to market changes. Along with problems of credit access, market incentives, production risk, and infrastructure, understanding the specific soil nutrient limitations and needs of small farmers and building the capacity of agrodealers to provide the services farmers require will influence how the agricultural sector develops, who benefits, and who loses.
