Organic Fertilizers in Sub-Saharan Farming Systems

摘要: Soil has played major roles throughout human history and civilizations. In sub-Saharan Africa, the soil been subjected to key challenges such as organic matter export, loss termites, burning, diversion competing uses. These issues lead a decline in fertility that threatens sustainability of actual agricultural systems. Therefore use fertilizers conservation agriculture is promoted. Farmers recycle resources by composting other practices. However, adoptions both have remained low due limited knowledge on these practices, lack policy support, insufficient labor. response, emphasis mineral Africa shifting over years. Here we review current role farming systems order clarify avenues for enhancing it. The points are (1) their increasing recognition systems, policy-makers increasingly supporting sustainable production (2) There an awareness need efficiency resources. (3) consensus most gains crop productivity achieved from combined application driving forward integrated management Africa. (4) Small farmers who generally unable apply recommended rates experimenting options upgrade inputs.
