Abstract : The increasing demand for freshwater resources, coupled with the growing need for sustainable agriculture, has led to the exploration of treated wastewater (TWW) as an alternative irrigation source. This study evaluates the impact of TWW irrigation on the physical and chemical properties of agricultural soil.Soil samples were collected from fieldsin Dodda Bhuhihal,Chikka Bhudihal and B.Kalpanhalli irrigated with TWW as surface irrigation , and analyzed for key physical properties, including dry density, bulk density, porosity, and moisture content, specific gravity, void ratio as well as chemical properties such as ph, electrical conductivity (EC) and nutrient concentrations (nitrogen, phosphorus, potassium). The results revealed a noticeable improvement in soil moisture retention and organic matter content due to TWW irrigation, contributing to enhanced fertility. Study concludes that while TWW irrigation can improve certain soil qualities and reduce dependence on freshwater, careful management is necessary to mitigate the potential long-term impacts of salinity and contaminants.
