Characterization and Classification of Obudu Mountains Steep Hillside Soils.

ESSOKA A. N.^*, ESSOKA P. A

Soil characterization helps us understand soils better which leads to their classification into categories. The steep hillside soils of three Obudu mountain ranges were selected for profile study for their morphological and physicochemical properties at Belekete, Bottom Hill and Belinge. The soils were well-drained and deeply weathered. The mean percentage of sand, silt and clay were 54 %, 59 % an...
