We describe for the first time a current indigenous soil management system in West Africa, in which targeted waste deposition transforms highly weathered, nutrient‐ and carbon‐poor tropical soils into enduringly fertile, carbon‐rich black soils, hereafter “African Dark Earths” (AfDE). In comparis...

Indigenous African soil enrichment as a climate‐smart sustainable agriculture alternative
The socio-economic values of fertile and carbon-rich Dark Earth soils are well described from the Amazon region. Very recently, Dark Earth soils were also identified in tropical West Africa, with comparable beneficial soil properties and plant growth-promoting effects. The impact of this manageme...
