Abstract
In this study, to estimate the transforming (runoff and leachate) rate of the livestock resources applying to agricultural crop land as fertilizer, field scale test was conducted and the results were obtained as follows. According to results of livestock resources effect to agricultural land, the total amount of harvested crop from testing bed was $0.437kg/m^2$, and nutrient contents were $0.024{\pm}0.006%$ and $0.020{\pm}0.004%$ for N and P, respectively. Dynamics of contaminants in the livestock resources to be supplied to agricultural crop land showed that concentrations were continuously decreased to the level of blank test bed until 60 days of planting. The amount of runoff from farm land showed the tendency to increase according to the increase of rainfall intensity. Run-off ratio of 10mm/h rainfall intensity for agricultural land showed that each contaminant concentration was increased due to rainfall intensity with 8 mm/h, specifically SS showed the highest increase.
