Margenot, Andrew J.Singh, Bal RamRao, Idupulapati M.Sommer, Rolf[Phosphorus fertilization and management in soils of Sub-Saharan Africa]Phosphorus fertilization and management in soils of Sub-Saharan Africa

Farming practices in sub-Saharan Africa have resulted in declining soil fertility. Hence, Green Manure Cover Crops (GMCC) are promoted for soil improvement and protection. Adoption of GMCCs by farmers, including integration in their cropping systems, requires a good understanding of the multi-dim...
