As in the forest zone, they are the best soils for agriculture.
The coastal savanna zone has an abundance of soil types, including tropical black earths, tropical gray earths, acid vleisols, and sodium vleisols.
Along the north and south, and to some extent along the west, the uplifted edges of the basin give rise to narrow plateaus between 1,000 and 2,000 feet (300 and 600 metres) high, bordered by impressive scarps.
The most outstanding are the Kwahu (Mampong) Scarp (Surrounding the basin on all of its sides, except in the east, is the dissected Precambrian peneplain, which rises to elevations of 500 to 1,000 feet above sea level and contains several distinct ranges as high as 2,000 feet.
Because of their intrinsic poverty in nutrients, most of the soils are heavily dependent upon the humus supplied by the vegetation cover.
There is thus a delicate balance between vegetation and soil fertility, which may be upset by uncontrolled burning or overuse., is determined largely by the interplay of two air masses: a hot, dry continental air mass that forms over the Sahara and a warm, humid maritime tropical air mass that forms over the South Atlantic.
The Paleozoic sediments are composed mostly of beds of shales (laminated sediments consisting mostly of particles of clay) and sandstones in which strata of and covers about 3,275 square miles (8,500 square km).
In the east the predominant rocks are less than 65 million years old, though there is a patch of Cretaceous sediments (about 65 to 145 million years old) near the Ghana-Togo border.
To the west of Axim, near the Côte d’Ivoire frontier, the rocks date to the Cretaceous Period.
Except for the tropical black earths, known locally as , most of these soils are of little importance agriculturally.
The Akuse clays fill a broad zone across the coastal savanna plains; although heavy and intractable, they respond well to cropping under irrigation and mechanical cultivation.
