Abstract
In this study, the nutrient removal capacity of paddy field was investigated. Paddy field was considered as a constructed wetland. The present study was conducted during a cropping period in a rice cultivation area located in Hampyung-gun, Jeollanamdo, Korea. Water balance and mass balance of nutrients were estimated after intensive field monitoring. The surface runoff losses of T-N and T-P were 20.82 kg/ha and 1.55 kg/ha, respectively. The losses were 13.2% and 6.4% of T-N and T-P input into paddy fields, respectively. The results showed that the paddy fields have nutrient removal function.
