Five soil samples were collected from two abattoirs study area and uncontaminated area was used as control. The physico-chemical parameters investigated include; soil pH, Carbon, Nitrogen and available phosphorus content, exchangeable bases (Na, K, C and Mg) and soil particle size using the standard technique. The abattoir effluent contaminated soils have the mean pH values between 6.30 and 6.33 and showed high significant difference in pH values compared to uncontaminated soil at 5% level of probability. The organic carbon content of abattoir effluents contaminated soils ranged between 1.57% and 1.54% this also showed significant difference at 5% level of probability. Exchangeable bases (Na, K, Ca and Mg) contents values obtained in the contaminated soils have much lower value compared to uncontaminated soil. Generally, the exchangeable bases contents values for the contaminated study area showed significant difference from uncontaminated study area except for the potassium values. Analysis of variance (ANOVA) at p=0.05 was used to further determines the differences among the factor investigated.
