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...

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...

Soil organic carbon (SOC) sequestration is important in the global carbon cycle and an integral part of many initiatives and policies to mitigate climate change. For efficient targeting of measures leading to SOC sequestration, it is necessary to know the actual SOC content (%) and a realistic ta...
