Assessment Of Seasonal Variations Of Chemical Fertilizers Residues In Agricultural Areas Of Najangud Taluk, Mysore District

Abstract

The use of chemical fertilizers to the agricultural farm lands has increased many folds during recent years. In order to study residual impact of the chemical fertilizer as well as nutrients inflow into the water resources has considerably increased water pollution problems. During the present study, seasonal variations of chemical fertilizer residues along and selected water quality parameters have been carried out. From the experimental results, it can be concluded that, a significant variations in urea and DAP residues was observed in all the three seasons. The maximum concentration of chemical fertilizers residues was observed during winter, followed by summer season, which implies, during rainy season urea and DAP residues were carried into nearby water resources, which may persist during winter season. In case of water quality parameters, except, nitrate and phosphate majority of the parameters were found to be within the desirable limits of WHO standards.
