ASSESMENT OF SULPHUR IN RELATION TO SELECTED PROPERTIES IN SOILS OF ILORIN EAST LOCAL GOVERNMENT, KWARA STATE

Abstract

A study was conducted on the sulphur content and its relationship with some selected soil properties at Ilorin East Local Government, Kwara State in 2021. An analysis of twenty samples each from two depths (0 - 15 cm and 15 – 30 cm) of soil on the study site was conducted to determine selected physical and chemical properties, total and available sulphur content. Results showed that the total sulphur content ranges from 1.15 to 37.25 mgkg^-1, the available sulphur content (HCL) ranges from 0.04 to 2.5 mgkg^-1 and the available sulphur content (EDTA extracted) ranges from 0.1 to 4.5 mgkg^-1. There were positive correlations observed between the different forms of sulphur within the soils, although total sulphur showed a negative correlation to available suphur (HCL) in the surface soils. All the forms of sulphur showed a negative correlation with organic carbon content and pH. Sodium, calcium, and potassium correlated positively with different forms of sulphur. It was observed that, sulphur content of the soils of Ilorin East Local Government Area were generally deficient. The top layer of the soils was low in sulphur content. Equilibrium between the different forms of sulphur present in the soil was also observed.
