  ABSTRACT: Soil is a basic natural resource for food production, the vast majority of food we consume is either directly or indirectly derived from soil. Soil quality determines the quantity and quality of foods grown. Protecting the soil’s physical, chemical and biological integrityistherefore of vital importance in safeguarding global food security. This paper evaluates the physical and chemical propertiesof soils in the rainforest of the Takamanda in Southwestern Cameroon and their implicationsonagricultural productivity and food security. Soils were randomly sampled using a bucket soil auger at the left, middle and right flank of the 50 ha Takamanda forest dynamic plot. Soils were sampled from three flanks at depths of 0 - 10 cm, 10 - 20 cm and 20 - 30 cm. Bulk density increased with soil depth in all the flanks. Soil nitrogen, organic carbon, potassium, magnesium, sodium, phosphorus and cation exchange capacity were greater in topsoil (0 - 10 cm) than subsoils. Soil Ca and pH were slightly greater at 20 - 30 cm soil depths with value of 0.45 cmol (+)/kg and 4.24 respectively. Soil C/N ratio was highest (13.12) in 10 - 20 cm soil depth though it was not significantly different from the other soil depths. To promote food production, an integrated cost-effective approach to soil management should comprise the use of acid-tolerant species of crop plants, efficient use of fertilizers, suitable crop rotations, crop diversification and agroforestry.
