The system consists of the relational database for agricultural NPS data, a data processing module, and a web site for the visual presentation online. The data collected from the Yongnam Irrigation District were used in this study. The database was constructed using MySQL Server 5.5 with meteorological, hydrological, water quality, soil characteristics, and farming factors. The data process module and web site were developed using Microsoft C# and ASP.NET, respectively. The data process module was composed of two submodule; data input module and data analysis module to validate data. The results of this study showed the applicability to a variety of agricultural NPS data. Furthermore, the system developed in this study are expected to provide an appropriate data management tool for agricultural NPS studies.
