The soils of the lower eastern slopes of the Cameroon mountain and their suitability for various perennial crops

On the eastern slopes of the Cameroon Mountains soils occurring below the 100- metre contour were surveyed on a scale 1:25,000. Most soils are young marine clay soils used for growing bananas, oilpalms, cocoa, rubber and tea. At some places there are lava streams from the mountains.A more general soil survey was made of the younger and older volcanic soils above the 100-metre contour line and a map, scale 1 : 100,000, was produced.The relative age of the various volcanic deposits could be estimated after completing the study of the origin, genesis and distribution of marine soils, that cover volcanic deposits in the lower part of the plain.The discovery of beach walls at different levels formed as a result of differences in sea-levels and gradual rise of the land, helped to solve various soil problems. Most soils are K-deficient, especially young volcanic soils
