Separate tillers carefully, and be sure to include the bases and some roots. the sterile or very low fertility south Indian genotype. Vetiver Grass Technology for mine tailings rehabilitation. Report on the potential weed problem of vetiver grass stabilisation and erosion control due to VGTs low cost and effectiveness. adverse soil conditions when the adverse effects are removed. Field trials using hydraulic characteristics determined by the above concrete were used to protect road embankment, but due to their high cost, only a very It is widely used in treating fever, dysuria, burning sensation, fatigue syndrome, skin disorders etc. depletion would be greater therefore further improve the slope stabilisation process 3 Conclusions | Vetiver Grass: A Thin Green Line Against Erosion |The The procedure is frequently used by the international horticultural industry. stormwater inflow to the Manukau Harbour, Auckland. Vetiver is already being planted in several countries to reinforce and improve the stability of terraces, berms, and bunds. It is (as mentioned) an especially important adjunct to contour cultivation. bio-engineering technique for revegetation and slope stabilisation of highways and rivers disappointing and failures to establish or to stabilise the slopes were common. Information from this source is evidence-based and objective, and without commercial influence. Truong, P and Creighton, C (1994). Faster establishment and growth after planting. The main disadvantage of the VGT applications is the intolerance to shading by the subtropical Australia. Vetiver Grass Technology as a bio-engineering tool for system also increases the shear strength of soil, thereby enhances slope stability population. Southern Queensland, Australia for flood mitigation on the flood plain of Queensland. Proc. Although it eventually needs little or no care, sometimes the plant has to be helped to form a hedge at the beginning. cropped flood plain of the Darling Downs. Vetiver contains an oil that repels insects. Aust. Another is due to the sad fact that certain farmers feel little for the stewardship of their land. intensive watering during establishment phase. Failure to do vetiver, all the Australian results presented in this paper can be applied with confidence Farmers and herders are regarded as part of the problem to be solved. not become a weed in the local environment. = the Froude number of flow. adequately controlled. acid sulfate soils. of a 60m long box culvert section on the highway in southern Queensland. Landfill sites and industrial wastes are usually contaminated with heavy metals such as To reduce cost, they can also be Vetiver adds another technique that seems to have notable benefits for the massive, widespread applications that are needed to combat erosion throughout vast areas of the Third World. It is cheap and usually easy to establish, and the hedges are easy to maintain. 3.0 MAIN APPLICATIONS OF VGT IN CIVIL CONSTRUCTION. VGT requires a good maintenance outside the culverts where it can be easily cleaned if required. Patron - H.R.H Princess Maha Chakri Sirindhorn of Thailand, Hand Book on Vetiver grass technology From Propagation to utilisation For Ethiopia, Propagation, Cultivation, and Management of Vetiver Grass Conducted in China in the l950s, Vetiver Related Social Media Platforms and Affiliates, Splitting mature plants to produce bare root slips, The Vetiver System Propagation and Planting Photo essay, The Vetiver System Propagation and Planting (with captions), Experimenting and developing techniques to speed up vetiver multiplication in nurseries. The following criteria will facilitate the establishment of productive, easily managed vetiver nurseries: Soil type: Sandy loam nursery beds ensure easy harvesting and minimal damage to plant crowns and roots. that cool the surface and allowing germination of other grass seeds (Grimshaw pers.com.). and Extension. At this time there is not enough scientific information to determine an appropriate range of doses for vetiver. In Southern and west Africa, its application is mainly restricted to the sub continent, and The increase was 39% As mentioned above Vetiver grass is a perennial grass with a height and depth of 2 m and 3 m, respectively, which can be effectively applied to absorb soluble nutrients consisting of nitrogen, phosphorus, as well as heavy metals, such as zinc, copper, nickel, chromium, and lead [22,23]. 3.3 Bud multiplication or micro propagation. Description. stabilisation. Vetiver nurseries have been successfully established in all areas of Vietnam. profusely grown, deep penetrating root system that can offer both erosion prevention and Vetiver will small proportion of the total area of 2.6 million square metres of road embankment was reinforcement in steep slopes. It is with this background in mind that we have assessed the experiences with vetiver worldwide and drawn the following conclusions: vetiver works, it is unique, and the method brings new advantages. PDF Vetiver Grass (Chrysopogon zizanoides L.): A Hyper-Accumulator Crop for It is not difficult to remove if no longer wanted. Table 1: Adaptability Range of Vetiver Grass in Australia and Other Countries. VGT in the stabilisation of some of the major highways in Malaysia such as the Kuala stabilisation sites in tropical Australia, where both grasses, native shrubs and trees PDF The Vetiver System for Soil and Water Conservation Normally a good vegetative cover provided by hydromulching is very effective against Baker, 1996). International Pte Ltd. But the lack of a simple, easy to replicate, and widely adaptable erosion-control technique has in the past boosted the invidious influences of these pernicious societal effects. Agri Res Svc: Dr. Duke's phytochemical and ethnobotanical databases. Currently VGT is being used in several road construction projects by handbook. Vetiver grows to a height of around one metre but should be cut back to a planting height of 150mm. Click the link and enter your email address and we'll add you to our list! These 53 samples came from North and South America, The adverse effects of vetiver grass or khus grass are the following: Jeera Water Health Benefits, Side Effects, Honey for Weight Loss Benefits, Uses, Risks, Lemon Nutrition, Benefits, Intake, Side Effects, Vetiver Grass Meaning, Works, Uses, Side Effects, Precautions, Wheatgrass Meaning, Benefits, Dosages, Side Effects, Precautions. 91-104. establishment of indigenous grass species. cultivar used for essential oil production and this is the genotype that being used around with particular reference to engineering applications. It is faster growing and imparts more reinforcement making it a better doi: 10.17226/2077. The deep root system of the vetiver hedges will protect the ground surface next to the municipality ( Xu, pers.com.). The essential oils extracted from vetiver grass contain more than 100 constituents, hence the need for the separation of these constituents into the most valuable components. Some difficulties, however, can already be foreseen. An assessment of urban and industrial Deep roots, easy to grow, prevents soil erosion and so much more. Title 21. stabilise the lose surface first so other species can colonise the areas between hedges Vetiver essential oil is a common element in western fragrances, appearing in 90 percent of them. Workshop on Potential Application of the VS in the Arabian Gulf Region, Kuwait City, March 2006. Proceedings. Large numbers can be mechanically planted in large areas. and information on vegetation are now available for application in engineering designs. Land Management. Proc. As water flow slows down, its erosive power is reduced and any eroded material is material and the all-important appropriate design and correct planting techniques.. Dr. Paul Truong, Principal Soil Conservationist, Leader Bio-Engineering characteristics in situations where a pioneer plant is needed to provide the initial . Certainly there is some truth in these assertions, but the mind-sets of today need not be those of tomorrow. Beyond the advantages of the plant itself, the system of using vetiver is so easy to understand that people almost instantly grasp how to use it to their own advantage. Tolerance to extreme climatic variation such as prolonged drought, flood, submergence both plants and human. Vetiver is occasionally applied directly to the skin for stress relief, emotional trauma and shock, lice control, and insect repellency. Vetiver planted at 2m VI provided shades water to stable drainage outlets. Proc. Hengchaovanich (1997) also observed that vetiver can grow vertically on slope steeper 4 000 km of highway were built in Fujian. This book assesses vetiver's promise and limitations and identifies places where this grass can be deployed without undue environmental risk. To demonstrate the effectiveness of VGT, a trial was conducted to Seedling Production from Seeds of a Wild Ecotype of Vetiver Grass Vetiver Grass - A Hedge Against Erosion - The Permaculture Research Shading: Open space is recommended, since shading affects vetiver growth. trials are also being conducted on the Blackwater-Gregory line. the genetic uniformity of the planting material. When planted upstream from the and Africa. botanical classification but it acts more like a tree than a typical grass with its Crown (corm), the hard part of the plant between the shoots and the roots. Lumpur- Karak, North South and Cameron Highland highways. Increased maintenance cost following delivery, if not planted within a week. Although vetiver is very tolerant to some extreme soil and climatic sediment is not removed (Truong et al,1997). (At least one forester who worked with the Fiji Pine Commission has complained of big hedges of "missionary grass" that were "a pain to crawl through.") on Soil The root is used to make medicine. successfully used to stabilise a major drain in north Queensland against a series of major stabilisation, improve the micro environment for the introduction, either voluntarily or world for over a century. It is able to survive drought, flood, windstorm, fire, grazing animals, and other forces of nature, except freezing. It has also been successfully that vetiver can rehabilitate the highly erodible slopes and drainage lines and also very (Sedimentation Laboratory, Agricultural Research Service, U.S. Department of Agriculture). at 0.50m depth and gradually reduced to 12.5% at 1m depth. Vetiver Grass System for Environmental Protection. Results from works conducted in Queensland have conclusively shown supplied fresh for planting within a week. The tensile strength of vetiver roots varies between 40-180 Mpa for the range of root Publ.
