This study was conducted to investigate the effect of swine liquid manure (SLM) and phosphorus fertilizer from September, 1998 to July, 1999 on the soil fertility on Italian ryegrass field, Cheju volcanic ash soil. pH (1st investigated), Mg (2nd investigated) and Cu content (2nd investigated) on soil grown by Italian ryegrass were significantly increased by an increase of fertilzier P(P0.05). Pig liquid manure application increased significantly pH(1 s), OM(1 st), Mg (2 nd), C/N ratio (1 and 2nd) and Cu(1 st and 2nd) content in soil(P0.05).
