Effect on soil temperature (ST) regime was assessed for a bioremediation product (Ecorem) made from local resource materials from Nigeria as part process kinetic study to establish its eco- toxicological significance. Influence of Ecorem- soil weight ratios (ESWR) was examined and predictive equations developed. Results showed daily temperatures fluctuations. Poled data revealed up to 4.4% ST (37.41 ¡Þ1.85oC) reduction by oil contamination. Ecorem increased the value by 1.12 to 3.93%. Temperature elevation varied with ESWR, giving positive correlations with coefficients of up to 0.950 (p = 0.013); which is a function of petroleum product type. However, study revealed that bioremediation using Ecorem runs at temperature variations favourable to improved crop production and from predictive equations, remediation project execution plans using Ecorem; for soils contaminated by petroleum products such as spent engine oil and crude oil, negative and positive errors of - 1.23% and + 1.54% from mean ST are recommended.
