Comparative Study of Physico-Chemical Parameters and Heavy Metal Detection in Agricultural Soil Irrigated By Sewage Water and Tube Well Water in Rewari City Rural

Present Comparative study revealed that Use of sewage water for irrigation of crops in Agricultural soil change the Physico- Chemical parameters and heavy metals content of the soil as compared to agricultural soil in which the crops are irrigated by tube well water or by canal water in nearby villages of Rewari city. Use of sewage water improves the fertility status of the soil as compare to the soil irrigated by natural sources. The percentage increase of soil samples investigated and analyzed for organic carbon (+49.19 %), total nitrogen (+109.09 %), available potassium (+49.03 %), available phosphorus (+72.08 %), electrical conductivity (+58.62 %) and also water holding capacity (+22.30). The sewage irrigation show remarkable increase in the concentration of heavy metals in the soil, i. e. Zn (+470.05 %) and Cu (+232.27 %) and Pb (+106.64 %). The results observed does not show much variation in the concentration of Fe (+51.40) and Cd (+27.41) metal in sewage irrigated soil compare to tube well irrigated soil. These are in permissible limits of Indian standard and show good soil quality in experimental site analyzed soil samples irrigated by sewage water but long term use of sewage effluents in the fields will certainly increase the heavy metals content and in future it will affect the human and animals of this area if the use of untreated sewage water continuously used by the farmers for the irrigation of this locality.
