Abstract
Most studies on soil characteristics have been centered on suitability for agricultural production and once a soil does not support crop production it is referred to as poor, unproductive, and finally abandoned. Such soil can be very useful for forest crop plantation. This study was designed to investigate characteristics and describe the forest soil in Ombi, southern Guinea savanna of Nigeria. Soil samples were collected randomly from three locations around the engineering department of Nasarawa State Polytechnic Lafia, at depth of 0-30cm. Samples (1kg each) were taken in plastics bags to the laboratory for studies. Physical and chemical properties were analyzed according to standard procedures. Results show that sand had the highest % in soil of the area (74.96). Bulk densities were within the same range (1.68; 1.77 and 1.78g/cm 3 ) for sand, silt and clay respectively. Sand had the highest porosity (37.7%) while clay had the least (31.6%). Aggregate stability was least for sand (9.74%) and highest for clay (56.82%). Soil reaction was neutral (7.05); nitrogen and CEC were 1.6 and 12.3 Cmol kg -1 among others, while organic carbon was 4.82g/kg -1 . The soil is described as light and falls under sandy loam. Forest plantation establishment will be worthwhile.
