Abstract
A field survey based study was conducted entitled ―Effect of sewage water irrigation on physico-chemical properties of different textured soils‖ in Department of Soil Science, CCS HAU Hisar taking five locations in Haryana to observe the effect of sewage water irrigation on physical, chemical and biological properties of soils in comparison to the non-sewage water. The five locations selected under study were Kurukshetra, Kaithal, Narwana, Jind and Charkhi Dadri. The sewage as well as non-sewage water quality was tested. The pH, EC, calcium carbonate, CEC, exchangeable cations, micronutrients, available NPK and heavy metals were found higher in the soils irrigated with sewage water as compared to the soils irrigated with non-sewage water. However, the infiltration rate of the soils irrigated with sewage water was observed low as compared to the infiltration rate of soils irrigated with non-sewage water. Further, the significant correlation was observed between the pH, EC and the exchangeable cations and anions. All the heavy metals detected in all the sites were found below the permissible limit. Therefore, it can be concluded that in the scarcity of irrigation water, sewage water can be used in the critical period of growth for life saving of the crops and the savings in terms of micro-nutrient deficiency amelioration practices can be done without expending on expensive nutrient supplements in plants.
