Stable Isotope Ratio Analysis for Tracing thee Major Pollution Source in Agricultural Watersheds

It has been acknowledged that fertilizer and animal waste have different ratio of \ulcornerN/\ulcornerN which is presented as a symbol of $\delta$\ulcornerN, and that the values of $\delta$\ulcornerN for fertilizer and animal waste are placed less than +8 $\textperthousand$ and higher than +10$\textperthousand$, respectively. By this reason, the demarcation range for the source nitrogen mass ratio is between +8$\textperthousand$ and +10$\textperthousand$. In this study, we would suggest a possible method to trace the major pollution basis using the nitrogen isotope analysis method for management of water quality.
