Abstract: The present investigation in relation to “Long term effect of sewage water irrigation on chemical properties and heavy metals contents of soil in peri urban areas of Nagpur district.” The field experiment was carried out in farmers field of Narsara, Bahadura and Vihirgaon villages of Nagpur district which are in the close vicinity of Nag river during 2022-2023. The sewage water irrigated through direct pipeline showed slightly lower soil reaction (pH 6.95) with higher EC (0.85 dS m^-1) and high organic carbon (8.5 g kg^-1) content. The available N, P, K status of sewage water irrigated soils through direct pipeline was appreciably higher as compared to other treatments. The concentration of micronutrients viz. Fe, Mn, Zn, Cu and heavy metals like Cd, Cr, Pb and Co were found comparatively higher in sewage water irrigated soils applied through direct pipeline. The concentration of these elements was observed to be greater than their critical concentration and lead to soil contamination.
