CHN_RY02 This series of images relates to the first use of vetiver for rail road stabilization in China. The site was a raised embankment, mainly sandfill, very difficult to compact and stabilize. Vetiver was used successfuly as shown in the next few slides.
CHN-RY06 China - Railroad stabilization. The site was a raised embankment, mainly sandfill, very difficult to compact and stabilize. You can see the rock used to stabilize the foot of the slope.
CHN-RY14 China - Railroad stabilization. The site was a raised embankment, mainly sandfill, very difficult to compact and stabilize. Here workmen prepare the slope surface for vetiver hedge planting.
CHN_RY03 China - Railroad stabilization. The site was a raised embankment, mainly sandfill, very difficult to compact and stabilize. Making a mud/fertilizer slurry to dip the roots in prior to planting - Standard practice in China to stimulate new root growth when using bare rooted planting material. This treatment insures that the root zone is kept humid during the transplanting process and that nutrients are immediately available to newly emerging roots.
