Soil degradation poses a serious threat to food production and rural livelihoods in sub-Saharan Africa1. Nutrient mining ,as a result of unsustainable farming practices, have left the soils unfertile (Fig.1). Green Manure Cover Crops (GMCC’s) are a promising intervention to improve soil health2.B...
