Abstract
This study was conducted in Kota district for characterization of wastewater irrigated soils of Kota district of Rajasthan. In Kota, urban and peri urban agriculture fields depends on particularly during summer season. The water quality significantly varies according to varies conditions. A quarterly survey was conducted and different characteristics of wastewater and source of waste water irrigated soils were determined. The irrigation effects of wastewater on soil properties were observed. The observation of sand content, pH and dehydrogenase activity were decreased and the other properties like Porosity, EC, BOD, COD, OC, available-NPK, SO4, Cl and heavy metals viz. Mn, Fe, Zn, Cu, Ni, Cd, Pb and Cr were increased. Observation of the impact of waste water on soil properties were studied in comparison with the reference tube well water irrigated soils collected from ten source points in district urban site. A slight decrease was observed during monsoon, it might be due to dilution effect of monsoon. Highest values were observed in summer of all study sites. Some parameters found above as the prescribed permission limits of Indian standards. Present investigation aim to determine the irrigation effects of wastewater on soil EC, pH, available- NPK, dehydrogenase activity and micronutrient content of Kota district of Rajasthan in India.
