Abstract: The present study deals with the assessment of changes in chemical characteristics of soils, irrigated with sewage water, in Kurukshetra and Charkhi Dadri areas of Haryana, India. Samples were collected (0-15 and 15-30 cm) from sewage and tube well water irrigated soils at various sites, where these waters are directly used for irrigating the crops. Soil pH, electrical conductivity (EC), organic carbon (OC), cation exchange capacity (CEC), calcium carbonate (CaCO3) exchangeable cations, macro and micro nutrients and heavy metals were estimated from these soils. The mean value of pH (8.20) was found highest in the soils irrigated with sewage water of Kurukshetra. The mean value of EC (0.72 dSm-1) was found highest in the soils of Charkhi Dadri irrigated with sewage water. The mean value of OC (1.01%), CaCO3 (1.99%) and CEC (18.50 cmol (+) kg-1) was found highest in soils of Kurukshetra irrigated with sewage water. The content of exchangeable cations like Ca2+, Mg2+, Na+ and K + were observed higher in soils irrigated with sewage water as compared to soils of irrigated with non-sewage water. The mean value of Ca2+ (8.78 cmol (+) kg-1), Mg2+ (4.98 cmol (+) kg-1) and Na+ (2.42 cmol (+) kg-1) was found highest in the soils irrigated with sewage water of Kurukshetra. But the mean value of K + (1.49 cmol (+) kg-1) was found highest in the soils irrigated with sewage water of Charkhi Dadri. The mean value of N (184.75 kg ha-1), P (28.91 kg ha-1) and K (271.50 kg ha-1) was found highest in the soils irrigated with sewage water of Kurukshetra. The content of micronutrients like (Zn, Cu, Fe and Mn) and heavy metals like (Cd, Cr, Pb and Co) were observed higher in soils irrigated with sewage water as compared to soils of irrigated with non-sewage water. The mean value of Zn (3.78 mg kg-1) and Cu (2.40 mg kg-1) was found highest in the soils irrigated with sewage water of Charkhi Dadri. But the mean value of Fe (18.23 mg kg-1) and Mg (16.19 mg kg-1) was found highest in the soils irrigated with sewage water of Kurukshetra. The Cr content was not detected in all the soils samples collected from different cities from sewage and non-sewage water irrigated sites. The mean value of Cd content was higher in sewage irrigated soil as compared to non-sewage irrigated soil. The mean value of Pb (0.51 mg kg-1) and Co (0.18 mg kg-1) was found highest in the soils irrigated with sewage water of Charkhi Dadri. The study suggests that sewage water irrigation led to beneficial changes in chemical properties of the soil, but increased the soil contamination of heavy metals. However, the intermittent use of clean water in such areas may not only reduce the metal contamination in the plants but will also maintain soil fertility.
