Abstract: Ten surface soil (0-15 cm) samples of different parent materials and physical and chemical properties were studied to relate sulphate sorption to soil properties. The results obtained showed that the soils are acidic with pH values rangeing from 4.30-6.20, they are sandy and generally of low nutrient content. The sorption capacity of the soils differs significantly and followed the order: Ntigha>Alayi>Owerrinta> Amaeke and Ohafia>Arochukwu>Isuikwuato>Bende> Umudike>Isiala-Ngwa Locations. Adsorption maximum ranged from 953.7/µg g-1 in Isiala-Ngwa to 2065.7/µg g-1 in Ntigha. The bonding energy K was highest in coastal plain sand and lowest in shale so also was Maximum Sulphur Buffering Capacity (MSBC). Some of the physical and chemical properties of the soil correlated significantly (p<0.05) with sulphate sorption parameters.
