초록

The nutrients runoff including nitrogen and phosphorous was investigated to find out the characteristics of nutrient discharge from the slurrigated area using digested animal manure. The results obtained are summarized as follows: 1.The concentrations of T-N, $NH_4$- N, EC, T- P and Cl- were high in flood runoff. 2.The concentration of nutrients by the surface runoff, except for $NO_3$-N, showed a tendency of increasing when the period of dry days before the rain fall was long. And the concentration of N$NO_3$-N increased in the inflow section where subsurface drainage flowed in. 3.The quality of water was generally influenced by the discharge of water quantity from slurrigated area. However the runoff concentration influenced the water quality when it was high enough. 4.To reduce loss of the nutrients and improve the fertilization effect, it is not recommended to apply slurry in rainy season.
