Geology & Soil

Knowledge of soil types in the area is an important pre-requisite for development planning since it helps to advise on the type of crops the soil can support.The main type of soil in this area is the Coastal Savannah Ochrosols. The coastal sands are pale yellow in colour and without humus or organic matter. 

These soils are suitable for coconut and shallots cultivation. On the Akwapim range, the soils are mainly pale and sandy with brushy quartzite occurring to the surface in most places. These soils are rich in sandstone and limestone that are good source of material for the construction industry

The red earths are usually developed in old and thoroughly weathered parent materials. They are typically loamy in texture near the surface becoming more clay below. The red soils are porous and well drained and support road development and also provide ample moisture storage at depth for deep rooting plants. Nutrients supplies are concentrated in the humus top-soil.
