It seems promising as a way for local people to involve, Rakiraki, Fiji. Hydraulic characteristics Based on the above, it is clear that the advantages of using the VGT as an bio-engineering tool outweigh its disadvantages particularly when the vetiver plant is used as a pioneer species. The resulting bare root slips can be dipped in various treatments, including rooting hormones, manure slurry (cow or horse tea), clay mud, or simple shallow water pools, until new roots appear. 74.
