The input reduction principle of agroecology is wrong when it comes to mineral fertilizer use in sub-Saharan Africa por Falconnier, Gatien N., Cardinael, R., Corbeels, Marc, Baudron, Frederic, Chivenge, Pauline P., Couedel, A., Ripoche, A., Affholder, F., Naudin, K., Benaillon, E., Rusinamhodzi, Leonard, Leroux, L., Vanlauwe, Bernard, Giller, Kenneth E.

“…Our analyses show that more mineral fertilizer is needed in SSA for five reasons: (i) the starting point in SSA is that agricultural production is “agroecological” by default, that is, very low mineral fertilizer use, widespread mixed crop-livestock systems and large crop diversity including legumes, but leading to poor soil fertility as a result of widespread soil nutrient mining, (ii) the nitrogen needs of crops cannot be adequately met solely through biological nitrogen fixation by legumes and recycling of animal manure, (iii) other nutrients like phosphorus and potassium need to be replaced continuously, (iv) mineral fertilizers, if used appropriately, cause little harm to the environment, and (v) reducing the use of mineral fertilizers would hamper productivity gains and contribute indirectly to agricultural expansion and to deforestation. …”
