The soils of the Obigbo flow station were analyzed for the impact of gas flare (heat radiation) on its physico-chemical properties. Sampling points labeled A, B, C, and D were 50m, 100m, 150m and 200m away from the flare barrier and at a depth of 0-15cm, 15-30cm, 30-45cm, 45-60cm. Samples were collected using a pyranometer and transported to the laboratory where it was prepared for laboratory analysis. During the routine soil analysis, pH, organic carbon, total exchangeable acidity and exchangeable (Na+, K+, Ca+, and Mg2+) were done using appropriate techniques. Findings from the study shows that distance from the flare point and depth of soil sampling were sources of variation in soil chemical and nutrient status. Soils from sample locations were generally acidic. Least pH values were obtained at point A. Higher values were obtained at farther distances (B, C. and D). Soils in the sampling area are well drained. Higher percentage organic matter was observed at point D (2.5, 2.3, 1.6, 1.0 at 0-15cm, 15-30cm, 30-45cm and 45-60cm respectively), with a steady decline per increase in sampling depth. Total exchangeable acidity, potassium and sodium were highest at top soil region of 0-15cm but declined as sampling depth increased. Magnesium, ECEC and calcium values followed the order sampling point B>C>D>A.
