This study mainly focused on assessment of the effects of VFS systems applied on an upland field in South Korea. In order to develop VFS systems for this study, the upland field affiliated with Kyungpook National University, located on Gyengsangbuk-do Gunwi-gun, southern part of South Korea, was selected. The size and slope of the study area are 1,500m2 and 7%. Various vegetation species including Kentucky bluegrass, Tall fescue, Milk vetch, Hairy vetch, Barley,and Rye were selected for the experiment, and the northern typed garlic was cultivated on the upland field. The monitoring system including flumes, water level gauges, a rainfall gauge were installed to assess the VFS systems. Germination and growth of the vegetations were monitored, and the effects of VFS were also investigated. As a result, the Barley and Rye VFS systems showed better possibilities for reducing non-point source pollution loads in early stage of their growth than the other vegetations. Further study will be proceeded to investigate with various field conditions.
