TL;DR: A four-year field study was carried out to investigate water management practices and losses of nitrogen (N) and phosphorus (P) in rice paddy irrigation fields in southern Korea.
Abstract: Assessment and control of nutrient losses from paddy fields is important to protect water quality of lakes and streams in Korea A four-year field study was carried out to investigate water management practices and losses of nitrogen (N) and phosphorus (P) in rice paddy irrigation fields in southern Korea The amount and water quality of rainfall, irrigation, surface drainage, and infiltration were measured and analyzed to estimate inputs and losses of N and P The observed irrigation amount surpassed consumptive use, and approximately 52 to 69 percent of inflow (precipitation plus irrigation) was lost to surface drainage Field data showed that significant amounts of irrigation water and rainfall were not effectively used for rice paddy culture Water quality data indicated that drainage from paddy fields could degrade the recipient water environment The nutrient balance indicated that significant amounts of nutrients (295 percent of total N and 86 percent of total P compared to input) were lost through surface drainage Furthermore, up to half the nutrient losses occurred during nonstorm periods The study results indicate that inadequate water management influences N and P losses during both storm and nonstorm periods Proper water management is required to reduce nutrient losses through surface drainage from paddy fields; this includes such measures as minimum irrigation, effective use of rainfall, adoption of proper drainage outlet structures, and minimized forced surface drainage

TL;DR: Based on the study of the relationship between ecological environment quality and socio-economic development, the authors proposed the Coastal Resource-environmental Carrying Capacity (CRECC) which including three subsystems (the Resource's system, the Ecological system, and the Socio-economical system), as well as 6 first-level indices and 20 s-level indicators.
