1. Vetiver grass is a plant that has spread deep into the root system distribution on Earth, making a straight wall-like Panel filter sediments and soil, soil screen, well it should be. Alternative education Try planting. Try planting vetiver grass to prevent erosion of soil in the area of development studies centre, and any other area that is widely somayangkwang. 2. The trial operation of planting vetiver, consider the characteristics of the terrain, broken down by nature of the area. G planting vetiver grass mountain, vetiver planting across the slope and in the Groove of the mountains. In order to prevent the erosion of the soil. And to help retain moisture in the soil. ข. planting vetiver grass on the slopes, perform the following. -Planting by the transformation. -Plant transformation. Convert each 1 or 2 concepts -For converting crops to planting crops according to Groove. C. planting vetiver grass around the pool to prevent the reservoir, the shallow due to sediment from soil erosion, as well as help maintain soil above. Basin and allows the forest area, gets multiple completion water quickly through ash. Discography. Planting vetiver planting vetiver as a water source area over the protective soil sludge and waste water flowing into the well to save the image. Before and after the operation as proof. 3. The results of experimental studies. All data should be stored on the growth of stems and roots. The ability to preserve the integrity of the soil and keep moisture in the soil and about the various species of vetiver grass. By the Department of highways is one of the agencies, the importance of soil and water resources conservation, including environmental impacts due to erosion of the soil-slope road. Has engaged in the development and widespread use of vetiver stemming from the initiative? Generally defined as the maintenance agency policy and construction on the highway, especially cut new planting vetiver grass to prevent erosion of soil slope North Slope vehicles and vehicles in various lines, along with promoting academic technical data distributes about vetiver as well as agencies in the region and make a video on TV project, planting vetiver about applications. Vetiver planting technique on the job. Target area of vetiver-mounted plasma display plant operations Department of highways is cutting through the soil slopes-north country (Back Slope) slope-land reclamation of country road (Side Slope) and tends to cause erosion of the soil. For the mountain in northern areas. In the South and Northeast, which are mainly covered with sand soil degradation that comes from the granite and sandstone is the target area in order to prevent the erosion of soil and soil conservation.
