Some Properties of Soils Formed Over Three Parent Materials in Imo State

Abstract

The study investigated properties of soils derived from different parent, materials, Random soil survey technique was used in siting profile pits. Soil profile pits were described according to FAO guidelines. Soil samples were air-dried and sieved with 2-mm aperture before routine determination of properties. Percentage coefficient of variation and simple correlation tools were used for soil data analysis. Results showed that sand varied from 810 g/kg (false bedded sandstone), 590-610 g/kg Imo clay shale) and 850-880 g/kg (coastal, plain sands). Clay varied from 100-170g/kg (False bedded sandstone), 300-310 g/kg (Imo Clay shale) and 110-140 g/kg (coastal plain sands). Organic matter ranged from 8.3-23.0 g/kg (False bedded sandstone), 11.0-28.1g/kg (Imo clay shale) and 6.3-25.0g/kg (Coastal Plain Sands), base saturation ranged from 23.0-28.0% (False bedded sandstone), 50.6- 52.1% (Imo clay shale) and 28.0 -35.0% (coastal plain, sands).
