BACKGROUND: It is essential to prioritize the exact andclear understanding of agricultural nonpoint sourcepollution (NPS) controls. The realistic policies and systemsshould also be developed based on this understanding. Therefore, this study aimed to present agricultural BestManagement Practices (BMPs) applicable for the fieldsbased on the Delphi survey result. METHODS AND RESULTS: This study deduced theevaluation items to assess each BMP for agricultural NPScontrol and conducted the surveying using the Delphimethod based on agricultural BMP experts. In addition, itson-the-spot application were evaluated. Considering itsimportance, technical, social and economic proprietiesshowed that political support was ranked first and followedby cost investment, labor investment, reduction effect andresident participation. The survey findings by agriculturalBMP experts showed the good performance of on-the-spotapplication can be achieved from fertilization by soiltesting, residue and green manure application and contourplowing which are applicable within a field. AgriculturalBMPs, highly applicable for the fields, were thecountermeasures that farmers who are the principal bodiesof agricultural NPS control could be participated directly. CONCLUSION: The active participation of farmers isessential for effective control of agricultural NPS. It isnecessary to establish various incentive systems.
