Does Africa have rich soil?

Why does Africa have poor soil?
African soils have an inherently poor fertility because they are very old and lack volcanic rejuvenation. Inappropriate land use, poor management and lack of input have led to a decline in productivity, soil erosion, salinization and loss of vegetation.
What type of soil does South Africa have?

Why is soil important in South Africa?
Under natural conditions, this dense matting of roots and microorganisms also stabilises the soil, and the spongy nature of good, healthy topsoil soaks up rainfall, reducing the risk of floods, retaining water just where plants need it and boosting the storage of groundwater.
