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, 200kgNha and 400kgNha. 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 (pc0.05). DM yields decreased according to continuous cultivation of corn. Total nitrogen(TN) contents of the whole corn decreased as the slope increased(p<0.05). TN content in SMFS treatments was higher than that of non-SMFS treatment but there was no significantly different between SMFS treatments. TN yields decreased significantly as the slope and the application level of SMFS increased(p<0.05). Nitrogen and organic matter yields in the runoff waters increased as the slope and application levels of SMFS increased. The runoff of nitrogen and organic matter was more affected by the increase of the slope than application levels of SMFS. (Key words : Corn, Runoff, Swine manure, Degree of slope, Lysimeter)
