Boron Distribution and Relationship with Selected Soil Properties in an Oil-Polluted Arenic Paleudult

E.U. Onweremadu and E.T. Eshett

This study investigated the distribution of soil boron and its relationship with some soil properties in a sandy Paleudult polluted by crude oil in southeastern Nigeria. Three pedons representing 3 land units influenced by crude oil spillage were dug, sampled and soil samples were used for various laboratory analyses. Results showed high values of organic carbon and cation exchange capacity in spilled sites. Iron and aluminium oxides were higher in non-spilled sites and generally increased with depth. Highest values of B (0.09-146 mmol kg-1) were found in spilled land unit while soil B ranged from 0.01-0.03 mmol kg-1 in non-spilled land unit. Soil B varied widely in spilled land units but little variation was observed in non-spilled site. Higher values of correlation coefficients were recorded in non-spilled land unit than spilled site. Best predictions was found when soil pH, surface area of clay, clay content and organic carbon predictors were combined linearly.
