Soil fertility management in sub-Saharan Africa por Masso, C., Nziguheba, Generose, Mutegi, J., Galy-Lacaux, C., Wendt, J., Butterbach-Bahl, Klaus, Wairegi, L.W.I., Datta, A.

“… (4) Proliferation of fake agricultural inputs has been reported in over 40–60% of the cases as a consequence of poor enforcement of quality standards. (5) In addition to blanket recommendations, fertilization has focused on nitrogen, phosphorus and potassium, with little emphasis on secondary and micro-nutrients as well as organic amendments or liming materials in acid soils, which has generally resulted in poor crop responses or low yield increments. (6) Effective adoption of integrated soil fertility management would result in at least doubling the current nutrient agronomic use efficiency in the smallholder farming systems and reduction of the actual yield gap averaged to more than 300% for cereal and legume crops. …”
