Agricultural non-point source pollution control field tests applying green control technologies in Dahan River Basin were operated in this project, and the quality of soil, runoff water and infiltration water were sampled and analyzed during the field tests for assessing the distribution of fertilizers in environment and the application effects of green control technology. Applying biochar, biological agents, microbial fertilizers and slow release fertilizers, nutrient absorption ratio of crops was increased and further nutrient mass in infiltration water and runoff water was reduced. However, it was necessary to appropriately adjust farming and technology application methods based on functions of technology and soil fertility conditions of farmland. Moreover, two technical training, nineteen on site technical direction, and the design of promotion poster were also finished in order to cultivate the ability and experience of applying green control technologie s locally. Judicious use of fertilizers and pollution reduction at the source were implemented to achieve the goal of environmental protection and implemented to achieve the goal of environmental protection and sustainable use.sustainable use.
