This study was conducted to investigate the effects of application levels of swine manure fermented with sawdust(SMFS) and degree of the slope on productivity of corn, and nitrogen and organic matter runoff in corn cultivation soil. Main plots were consisted of the degree of slope, such as 0, 5 and 10, and the subplots consisted of application levels of SMFS, such as control, 200kgN/ha and 400kgN/ha. Lysimeter was constructed with 0.33m width, 3m length and 0.4m height. Dry matter(DM) yields of corn decreased as the slope increased but there was no significant differences between the degree of the slope. DM yields increased significantly as application levels of SMFS increased (p0.05).
