Photo: 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.

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.

Photo: CHN_RY05 China - Railroad stabilization. The site was a raised embankment, mainly sandfill, very difficult to compact and stabilize. You can see three rows of newly planted vetiver hedgerows evenly spaced above the rock foundation at the base of the railroad embankment.

Australia - Railroads in Queensland are now using vetiver to stabilize problem areas, such as this tunnel entrance

Vetiver newly planted and used to stabilize embankment and reduce sediment and rubble entering the drain, thus greatly reducing maintenance costs over time to clean out the drains that would normally fill with sediments if vetiver hedges were not present.

Vetiver two months later used to stabilize embankment and reduce sediment and rubble entering drain, thus greatly reducing maintenance costs over time to clean out the drains that would normally fill with sediments if vetiver hedges were not present.
