Abstract:
The objectives of present study were to determine the effects of wastewater irrigation effects on physical, chemical and biological indicators of soils of Bundi district of Rajasthan to assess soil quality in reference to tube well water. However, the quality of water and conditions under which water is used are varying significantly. A quarterly survey was conducted and 40 soil samples from wastewater and 08 from tube well irrigated sites were collected. The different soil properties of wastewater and tube well water irrigated soils were determined. The sand content, soil pH and soil dehydrogenase activity were decreased due to wastewater irrigation. The soil porosity, EC, OC, available-NPK, SO^-₄, Cl^-, heavy metals (Mn, Fe, Zn, Cu, Ni, Cd, Pb and Cr) were observed higher in wastewater irrigated soils as compared to reference tube well water irrigated soils. A slight decrease was observed during monsoon, it might be due to dilution effects. Highest values were observed in summer of all study sites. Some parameters found above as the prescribed permission limits of Indian standards.
