This study was conducted to evaluate mineral content of Winter Rye, Nitrogen Balance, Soil chemical characteristics and NO,-N level in infiltration water as affected by different slurry application on the basis of N contents respectively and was arranged as a randomized complete block design with seven treatments (chemical fertilizer 160kg Nha, cattle slurry 160 . 320 - 480kg Nha, swine slurry 160 - 320 - 480kg Nha) and conducted at National Livestock Research Institute, RDA, in Suweon fiom Sep. 1996. to Apr. 1997. The results obtained are summarized as follows : Nirogen, Phosphorous, Calcium and Potassium of Winter Rye slightly increased as slurry application level was increased (p<O.O5), but not significant difference was found Magnesium, Cap ratio and W(Ca+Mg) equivalent ratio of Winter Rye. $NO_3$-N content ($\mu$g/g) of Winter Rye was shown fiom 780 to 1,462 in all treatments, especially , the swine slurry plots were significantly higher than that of cattle sluny plots (p < 0.05). As slurry application increased, show a marked trend toward surplus N input in all treatment. The pH of the topsoil (0~IOcm) was shown 6om 5.1 to 5.4 except the plot of chemical fertilizer before experiment pH of 5.1, but the pH of the subsoil (10~20cm) tended not to be regular. The content of available ,$P_2O_5$ inaeased with the increased application of slurry, particularly, the topsoil (O- 1Ocm) were much higher than the subsoil (10~20cm). The $NO_3$-N content of infiltration water (depth:lm) was increased as affected by sluny application.
