| Research Abstract |
The vegetation sheet is being used as one of the erosion prevention of the surface soil. That method, however, has disadvantages such as that there is the preferable season. In addition, both the seed and the nutrient contained in the vegetation sheet are flushed by the heavy rainfall on the slope, then the growth of vegetation is obstructed. In this study a method of temporarily stabilizing the surface soil until the seed germinates from the vegetation sheet was proposed. This method uses the processing liquid material that doesn't influence a slope and surrounding environment. As the result of outdoor and laboratory testing concerning the vegetation activity and water retentivity, the applicability and the limitations of this method have made clear.
