Abstract— The physicochemical properties and heavy metals in both vegetated and non-vegetated spoil soils in Jos Plateau were determined. Three dug soil profiles and thirty three composite soil samples were collected with auger at depths of 0 – 15cm, 15 – 30cm and 30 – 50cm and analysed using standard methods. The results showed mean value ranges of 4.58 – 5.28 pH, 0.09 – 1.46 Organic matter, 42 84% Sand, 6 – 46% clay, 5 -29% silt, 0.022 – 0.110% total nitrogen, 14.80 – 41.44ppm available phosphorus, 3.13 – 5.00meq/100g exchangeable calcium, 1.45 – 2.35meq/100g exchangeable magnesium, 0.04 – 0.51meq/100g exchangeable potassium, 0.15 – 0.20meq/100g exchangeable sodium, 8.16 – 12.28meq/100g CEC126.80 – 778.33ppm Fe, 0.16 – 0.44ppm Al and 5.50 – 23.50ppm Mn. The soils were found to be predominantly Sandy Clay Loam, acidic and deficient in nutrients, Nitrogen, Phosphorus and Exchangeable Bases. The concentrations of most parameters were higher in the cultivated spoil soils than in the uncultivated spoil soils. Land amendment materials such as organic wastes and town refuse ash should be applied to the soils in the area.
