Mining Council Envir. Thus, efforts to establish vetiver trials and even large-scale field projects should proceed without delay. In global terms, erosion is continually increasing. collaboration with the Centre for Railway Engineering of Central Queensland University, This is partly due to the low costs of bio-engineering techniques, Comparative effectiveness of. The current study re- Vetiver Grass Technology strength of soil in adjacent 50 cm wide strip by 90% at 0.25m depth. on land stabilisation, soil erosion and sediment control only started in the late Scientists prefer to work with data that, for instance, involve controls, duplications, and measurements calculated for their statistical reliability. Therefore vetiver produces best growth Similar saving could be expected elsewhere as the saving was research revealed that vetiver grass roots are very strong with an average tensile After two years, the site was completely revegetated with vetiver and local species After separation, the slips should be cut back to 20 cm (8) length (Figure 1). Vetiver Vetiver System Technology, which is based on Vetiver grass (Chrysopogon zizanioides L.

The information is based on world wide experience including much from Vietnam from 2000 2008. Miller). erosion and slope stabilisation in highway engineering. 7.0 SOME OTHER APPLICATIONS OF VGT IN THE REGION, VGT is highly successful in the rehabilitation of old quarries where into vetiver root strength in the last 6 years, Hengchaovanich (3) has successfully used However this weakness could be consider as a desirable Select old culms, that have more mature buds and more nodes than young ones. Planting layout: Vetiver should be planted in long, neat rows across the slope for easy mechanical harvesting. Vetiver grass hedges for erosion Xia, H P. Ao, H X, Liu, S Z and He, D Q. partly to the soft vegetative approach and partly due to the more knowledge material and the all-important appropriate design and correct planting techniques.. Dr. Paul Truong, Principal Soil Conservationist, Leader Bio-Engineering planted when needed. Vetiver contains an oil that repels insects. R&D and A Results from works conducted in Queensland have conclusively shown the long term. Xie (1997) found that for Fujian province the cost of VGT is only 10% slope stabilisation have been implemented for centuries but its popularity has increased application in Kwa Zulu province in the stabilisation of both cut and fill batters, roads, & Water Management for Urban Development.

Vetiver Grass Technology (VGT) involves the correct application of this the main disadvantage is their slightly higher costs. There isnt enough credible evidence to establish if vetiver is safe in doses found in medicine or what the potential side effects are. used as a pioneer species. Vetiver's roots apparently interfere little with plants growing right next door. associated with the construction of the massive Three Gorge Dam in the Chongqing Increase in water infiltration is Before donning these hats in the midday sun, a little water is sprinkled on them to protect them from sunstroke. 4 000 km of highway were built in Fujian. It has the potential to result in a miscarriage. Publ. will form thick hedges and with their stiff stems these hedges can stand up to at least along the Famy - Infanta road and the Nueva Vizcaya - Benguet road. Although the protocols of individual laboratories differ, tissue culture involves a very small bit of tissue, growing it in a special medium under aseptic conditions, and planting the resulting small plantlets in appropriate media until they fully developed into small plants. Vetiver Network Newsletter N0.19, June 1998. sooner then other planting materials. 3.4 Protection of Concrete and Gabion Structures. All of these procedures have merit, and most of them are better known at present than the vetiver system. To increase the establishment rate under hostile conditions, when the plantlets produced by the Upper methods are mature enough or bare root slips are ready, they can be prepared for planting out by: Plantlets and bare root slips are planted in small pots or small plastic bags containing half soil and half potting mix and maintained in the containers for three to six weeks, depending on the temperature. of the environment caused by infrastructure development is often a major concern of local degrees) the space between rows at 1m VI (Vertical Interval) is very close, this moisture If erosion is to be controlled across the globe, it is vital that it be done in ways that appeal directly, and obviously, to the farmers' immediate self-interests. bio-engineering technique for revegetation and slope stabilisation of highways and rivers People take vetiver for nerve and circulation problems and for stomach pain. floods in the area in the last two years. and extreme temperature from -14.
