Sustainable use of soil on which agriculture depends is absolutely necessary for agricultural productivity. Soil samples were collected from two auto-mechanic workshops sited at Technical College Road (Station A) and Textile Mill Road (Station B) while the control was at EDPA Housing Estate, all in Benin City with the aid of a split soil core sampler at a depth of 0  10cm. The Physicochemical parameters of the samples were analysed using standard methods and revealed pH mean value of 7.27 at station A and 6.83 at station B respectively.
