Decomposition is a key process in nutrient cycling and the formation of soil organic carbon. This study examines the physico-chemical properties of soils in different habitat types in the disturbed and undisturbed Takamanda rainforest. A total of 180 soil samples were collected from the different habitat types of the two forest sites. At each of the sites, soil samples were collected from the ridge tops (crest of a ridge), hilly slopes (side of a ridge), plains (low land), swamps (low land area saturated with water) and valley bottoms (trough surrounded by ridges). Soil samples were collected at 0-10 cm, 10-20 cm, 20-30 cm, 30-40 Original Research Article
