Research of green control technology for agricultural non-point source pollution was conducted in this project. The management strategies of agricultural non-point source pollution in the United States, the Netherlands, the United Kingdom, Japan, and South Korea and etc. were collected and evaluated, and the common best management practices and green control technologies for agricultural non-point source pollution were explored as well. This project analyzed the source and amount of pollution discharges in nine rivers, and proposed applicable management strategies. Furthermore, with different quantity of fertilizers addition and the application of phototrophic bacteria, the results of field test in Taipei, Taoyuan, and Taitung conclued that phototrophic bacteria could promote the tested crops to effectively acquire nutrients with similar harvest compared to the application without phtotrophic bacteria. Conversely, excessive fertilization might not be necessary to enhance the crops growth and cause crops damage. As the fertilizers addition increased, nutrients mass in infiltration water and runoff water was higher either because most fertilizers were lost rapidly with rainfall or irrigation water. Moreover, three expert consultation meetings, two promotional activities, and the promotion guideline were completed to support government’s future work regarding the application of green control technologies for agricultural non-point source pollution mitigtion.
