This study carried out to investigate the effects of the types of animal manure and the dogies of the slope on productivity of com and the runoff of nitrogen and phosphorus in corn cultivation soil. Main plots were consisted of the degrees of slope, such as $0\%;9\%$ and $18\%$ and the subplots on consisted of the types of animal manure, such as chemical fertilizer (CF), compost of swine manure fermented with sawdust (CSMFS), and cattle slurry (CS). Erosion was constructed with 0.33 m width, 3 m length and 0.4 m height. The results obtained were summarized as follows; 1. Dry matter(DM) yield of corn decreased by an enhancement of the degrees of slope DM yield reveals that there is an increase in order CS > CF > CSMFS. 2. Nitrogen contents of the whole corn reveals that there is an increase in order CF>CS>CSMFS. However, nitrogen content was not affected by the degrees of slope. 3. Nitrogen yields (NY) of com decreased by an enhancement of the degrees of slope. NY of CS increased more than 2.0 fold as compared CSMFS. 4. Mineral nitrogen content in the runoff during the experiment was hardly influenced by both the degrees of slope and the types of animal manure. 5. $NO_3$ - N in the runoff during the experiment increased by an enhancement of the degrees of slope. 6. In the degrees of slope used in this experiment, $NH_4$-N and $PO_4$-P content in runoff was lower than 8 ug / ul and 1 ug/ul, respectively.
