Abstract– Physico-chemical parameter of soil near brick kiln of Mathahi village of Madhepura district was examined and compared with physico-chemical parameter of soil half km away from brick kiln. It was observed that the pH value was lowest in all directions at 100mt away from brick kiln followed by 50mt away and 150mt away. Electrical conductivity doubled at each spot. Nitrogen content, Phosphorus content and Potash content also decreased near brick kiln. The pH was lowest (5.8) at 100mts away from brick kiln in its east side, pH 5.4 at North and west side and 5.5 in South side. The lowest value of percentage organic carbon in soil was at 100mt away in east side (0.35). Nitrogen was also lower near all spots of brick kiln. The lowest value was observed in east side at 100mt away from brick kiln (42.35kg/Ha). Phosphorus was also lowest at this spot (4.3kg/Ha). The lowest value of Potash was observed at 100mt away from brick kiln in west side (100.6).
Key words: Physico-chemical parameters, Brick kiln, pH, Electrical conductivity
