This study was conducted to determine the effects of application levels of pig slurry on the characteristics of runoff water in volcanic ash soil in Jeju, Korea. This study was arranged in randomized complete block design. The data represent the means of the three experiments. Experimental plots were consisted of five treatments such as no fertilizer, chemical fertilizer at 200kg N/ha/year and pig slurry levels at 200, 400 and 600kg N/ha/year. The concentrations of BOD and COD in 600kg N/ha pig slurry were significantly higher (p less than 0.05) than those of the other treatments at initial sampling at 12 days after application.
