Calcareous montmorillonitic black clays, occupying 1, 000 sq miles on undulating coastal plains in S.E. Ghana, overly basic gneisses & schists. The soils are deficient in N & P. Annual rainfall is 30-50 inches with maximum rain in June & a less pronounced peak in October. During the severe dry season the soil cracks into vertical columns & "puffs" are formed, sometimes bringing the subsoil to the surface. When puffs & shelves become continuous, wavy gilgae formations are found; continuous shelves & discontinuous puffs form lattice gilgae. The land is uncultivated, but rice & sugarcane could be grown with fertilizers & irrigation. (Abstract retrieved from CAB Abstracts by CABI’s permission)Downloads
