Effects of Pig Slurry Application on the Characteristics of Runoff and Leaching Water in Volcanic Ash Soil in Jeju
This experiment was conducted to determine the effects of applying level of pig slurry on the characteristics of runoff and leaching water in lysimeter. Treatments were broken down into five treatments such as non chemical fertilizer, chemical fertilizer (200kg N/ha) and pig slurry (200, 400, 600kg N/ha), and 3-timerepeated randomized complete block design was fulfilled. The concentrations of NO3-N was raised(p<0.05) in proportion to the applying level of pig slurry. NO3-N concentration of leaching water collected from soil depth 20cm and 40cm was intensified as the applying level of pig slurry was higher (p<0.05) in pig slurry 600kg N/ha application. In conclusion, pig slurry at the volcanic ash soil in Jeju area can replace the chemical fertilizer as it is tested that applying 200kg N/ha of pig slurry and chemical fertilizer show the same productivity of sorghum×sudangrass hybrid. But more than 200kg N/ha of pig slurry may not be appropriate because it may contaminate the runoff and leaching water even though it may increase for the forage productivity.
