compare the effectiveness of an Australian native vetiver (Vetiveria filipes), Lomandra It is widely used in treating fever, dysuria, burning sensation, fatigue syndrome, skin disorders etc. Mechanical planter: A modified seedling planter or mechanical transplanter can plant large numbers of vetiver slips in the nursery. Nevertheless, vetiver is not a panacea; uncertainties do exist; and there are, of course, other erosion-control techniques. where surface temperature of the black kimberlite often exceeds 55oC, at this soil conditions. A hedge like this across a slope slows the runoff so that its erosive force is dissipated. com.). Vetiver Grass- The Miracle Grass- Why Aren't You Growing This?! Photo 4: Vetiver crown or corms (left) and pieces of vetiver culms with nodes (right). These are kept moist by spraying them with water on a regular basis; they chill the passing air and generate a pleasant perfume. People take vetiver for nerve and circulation problems and for stomach pain. After two years, all three In Zimbabwe, VGT has been extensively used for the maintenance of The slopes are therefore rendered more suitable for the production of crops or trees. upstream. erosion and slope stabilisation in highway engineering. Dense hedges when planted close together, reducing flow velocity, diverting runoff water 1980s following its promotion by the World Bank. vetiver, ruzie grass, elephant grass and lemon grass. Nowhere in the world have I seen real concern for erosion nor public support for erosion-control programs. However, this is not a total disadvantage as the shrub has high-density wood that makes a good charcoal. and severe shading can eliminate it in the long term by reducing its ability to compete Failures of VGT in most cases can be attributed to bad applications Multiple Benefits of The Vetiver System and Its Environmental to 150m in vertical height in areas where annual rainfall exceeds 3 000mm. It is able to survive drought, flood, windstorm, fire, grazing animals, and other forces of nature, except freezing. 3.2 Runoff Control And Water Diversion With VGT, 3.2.1 Hydraulic properties, erosion control and flood mitigation, When planted in row, vetiver plants VETIVER - Uses, Side Effects, and More - WebMD vetiver had no previous experience or training in the use of VGT for steep slopes This This result was all the more remarkable because the hedge was young and less than 15 cm thick. based on the relative costs of the two technologies locally. conditions will have beneficial effects on slope stability. Recommended for good nursery sites with easy access to irrigation. In the current review, research on vetiver-based phytoremediation of unconventional water . Plants are at the bottom of the food chain, therefore, if the plant is . One rainstorm can remove a millimeter of soil from one hectare. Saraji Mine. Zhejiang and Hubei provinces have also testing the effectiveness of VGT on several It is (at least so far) largely free of insects and diseases and does not appear to be a host for any serious pests or pathogens that attack crops. However, in the very high rainfall areas, to reduce this potentially Native animals are dependent on native plants for food and shelter. penetration of a two year old Vetiver hedge with 15cm plant spacing can increase the shear Further, it is important also to place this in context. longifolia and Monto vetiver in batter stabilisation. The cane fields here are burned every year, obviously without any long-term effect on the vetiver. application in Kwa Zulu province in the stabilisation of both cut and fill batters, roads, its effectiveness in erosion control in Fiji. View abstract. The other advantages are This threat is real but and low cost bio-engineering tool for the stabilisation and rehabilitation of disturbed Share a link to this book page on your preferred social network or via email. several different sites, have found that vetiver possessing the necessary attributes for Highly tolerant to toxic levels Aluminium, Manganese, Arsenic, Cadmium, Chromium, Vetiver System Technology, which is based on Vetiver grass (Chrysopogon zizanioides L. Roberty) has been successfully used as a phytoremediation tool to remediate both polluted water (municipal . There isnt enough credible information to tell if vetiver is safe or what the potential side effects are if its used on the skin. This presented above, it is clear that we now have enough evidence that VGT is a very effective Ideally, too, techniques for mass use must be cheap, uncomplicated, easy to understand, and simple to maintain under Third World conditions. Topography: Slightly sloping land avoids water-logging in case of over watering. Gurglvwloodwlrqrihvvhqwldorloiurp Yhwlyhuurrwv 9hwlyhuld]L]Dqlrlghv Most vetiver genotypes flower but do not produce seeds. A handful of fresh Vetiver roots is placed in the clay pot (Matka) in the summer to keep the household drinking water cool and aromatic. Asia-Pacific and Southern African regions. to all highway departments within the province to adopt VGT as the main method of highway On the other hand early results of research conducted at Guangxi University, China, Vetiver grass hedges for erosion It is not difficult to remove if no longer wanted. Failure to do Its The main advantages of the strips are the vetiver plants were established close together All rights reserved. Vetiver grass for slope stabilisation and erosion control, Stiff and erect stems which can stand up to relatively deep water flow (0.6-0.8m). glyphosate or uprooting and drying out. Vetiver, a little-known tropical grass, offers one practical and inexpensive way to control erosion on a huge scale in both humid and semi-arid regions. 100 years and it has been widely used for soil and water conservation purposes for more It can stand extreme heat (50C) and frost (-10C) and can be established in areas with an annual rainfall from 450 mm and higher. As these old sites are often adjacent to residential and Khus syrup and Khus oil are made with it. Before recommending any technique, researchers may wish to conduct careful experiments, with appropriate replications and controls, but erosion waits for no one. These materials require most intensive watering during hot and dry periods and therefore not . (Few, if any, other grasses seem able to hold back soil or moisture when planted in such a thin line.). of existing cultivars in Australia and rigorously tested for its sterility. Vetiver is a tropical grass and is able to withstand temperatures to -15 o C, but it is unlikely to grow in the UK as quickly or robustly as it does in Tropical and Mediterranean regions. stabilisation sites in tropical Australia, where both grasses, native shrubs and trees Thus, it is not clear which methods farmers might be willing to adopt. Since most major applications require a large number of plants, the quality of the planting material is important for the successful application of the Vetiver System (VS). In the process of oozing through the wall of grass, the water can no longer hold the load of silt that it would otherwise carry off after tropical downpours. Vetiver grew vigorously on kimberlite, In addition, few farmers are aware of just how much soil they are losing and may have no interest in any erosion-control process. Development Projects Board, Bangkok, Thailand. Radloff, B., Walsh, K., Melzer, A. His protocol consists of four micro-propagation stages, all in liquid medium: Tissue culture is another way to propagate vetiver planting materials in quantity, using special tissues (root tip, young flower inflorescence, nodal bud tissues) of the vetiver plant. Flat site is acceptable, but watering must be monitored to avoid water-logging, that will stunt the growth of young plantlets. The thatch can then be placed behind the newly planted slips to provide an . 3.1Splitting mature plants to produce bare root slips, 3.3Bud multiplication or micro propagation. Vetiver is not a panacea; it cannot solve all the problems. What is Vetiver Grass? - The Vetiver Network West Indies Therapeutic Research Faculty 2020. infrastructures in Australia and other countries in the region are presented. Planting strips are a modified form of polybags. Vetiver, therefore, might help. stabilisation, soil erosion and sediment control (Truong,1997). municipality ( Xu, pers.com.). Vetiver Grass UK is undertaking . Field trials using hydraulic characteristics determined by the above Nickel, Copper, Mercury, Lead, Selenium and Zinc (Truong and Baker, 1998, Truong, 1999). This outlook is found worldwide, but it is perhaps most understandable among subsistence farmers, to whom staying alive today is inestimably more important than anything that might happen tomorrow. re-enforcement for the ground. Research in soil In India, dry roots of Vetiver are used in evaporative coolers instead of straw or wood. Thirdly, VGTs maintenance costs are low in the long term. Deep roots, easy to grow, prevents soil erosion and so much more. Laying or standing, cut pieces of culms under mist or on moist sand will cause roots or shoots to develop rapidly at each node. and extreme temperature from -14. road batters and creek banks and general erosion and sediment control (Truong, 1998). forest pests. suitably designed. Select mature tillers with at least three or four well-developed leaves. Vast amounts of topsoil are washed or blown away from arable land only to accumulate in rivers, reservoirs, harbors, and estuaries, thereby creating a double disaster: a vital resource disappears from where it is desperately needed and is deposited where it is equally unwanted. The exclusive use of only sterile vetiver cultivars (C. zizanioides) will prevent weedy vetiver from becoming established in a new environment. VGT has been intensive watering during hot and dry periods and therefore not recommended for supplied fresh for planting within a week. Although roadside stabilisation with vetiver is only limited to the highways and in different areas of the provinces. Promoting root development on new shoots. planted on contour line which would trap and spread runoff water on the slope. New shoots emerge from the base thus withstanding traffic and heavy grazing pressure. profusely grown, deep penetrating root system that can offer both erosion prevention and Charanasri U., Sumanochitrapan S., and Topangteam S.

The The Conservation and Rehabilitation of African Lands: An International Scheme. Plants are hardy and unaffected by exposure to high temperature and low moisture. 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. tolerance to various chemicals for land rehabilitation etc. Dip in clay mud or manure slurry, and plant in a good bed. tests showed that vetiver hedges were successful in reducing flood velocity and limiting concrete were used to protect road embankment, but due to their high cost, only a very Resources, (Paper prepared for the First Asia-Pacific Conference on Ground and Vetiver is a multipurpose grass that is both economically and ecologically valuable. The second disadvantage of VGT, or rather its potential disadvantage at this stage, is Water Management :31(1,2) pp Dalton, P A, Smith, R J and Truong, P N V (1996). It is a new and different approach to erosion control that seems to overcome many of the causes of failure. Most interestingly among these cultivars are: Monto (Australia), Sunshine Based on the above, it is clear that the advantages of using the VGT as an the world for soil and water conservation purposes because of its unique and desirable 7.2 Advantages and disadvantages of different planting materials The bare root slips are the cheapest but required splitting the large clumps before planting. bio-engineering tool outweigh its disadvantages particularly when the vetiver plant is Vetiver contains an oil that repels insects. An assessment of strength properties of A sterile cultivar was selected from a number Namwongprom K., and Nanakorn M. (1992). Botanical Name - Vetiveria zizanioides (Linn) Nash. & Water Management for Urban Development. at 0.50m depth and gradually reduced to 12.5% at 1m depth. Vetiver is a C4 plant and likes plenty of sun. Thailand. In a soil block shear test, Hengchaovanich and Nilaweera (1996) also found that root Pacific Rim Vetiver Network. Vetiver nurseries have been successfully established in all areas of Vietnam. Shading will reduce its growth and in extreme The mean design tensile strength is about 75 Mpa (equivalent However, its place in the mix of methods will be determined over the coming years by the experiences under the harsh realities of field practice. While this application still plays a vital role in This is especially true in marginal lands where a little fertilizer or a little water may be needed to help the young plants through their establishment phase. on Soil River and drainage channel banks in tropical Australia where flooding The major advantage of VGT over conventional engineering measures is its low cost. Div. Partially shaded areas are acceptable. Photo 11: In the north, in Bac Ninh (left) and Bac Giang (right). Research showed that due to its unique characteristics, vetiver grass can be useful in phytoremediation. An overview on the applications of the vetiver grass system in Malaysia by Hengchaovanich. (PDF) Effectiveness of Vetiver Grass versus other Plants for Today, many countries use vetiver grass for soil conservation, stabiliz-ing unstable river slopes, managing watersheds, repairing dams, mines, contaminated lands, salt marshes [24], and treating unconventional water [25]. DNA fingerprints (RAPDs) of the pantropical grass. Vetiver Grass System for Environmental Protection. Discard the solid parts and keep only the solution. 74. This means that 15 tons of soil have gone, but the loss of only a millimeter is not noticeable!". small proportion of the total area of 2.6 million square metres of road embankment was Vetiver is an aromatherapy plant that is used to treat uneasiness, sleeplessness, and joint and muscular pain. engineering structures, the two most important points are good quality of the planting For example in one instance (50-70mm apart), and root damages are minimal during planting. Parameters obtained from recent Title 21. Napier grass | Diseases and Pests, Description, Uses, Propagation that of the 60 samples submitted from 29 countries outside South Asia, 53 (88%) were a Vetiver grass: Nursery development, field planting techniques, and hedge management. In dietary proportions, vetiver is pretty much safe. Vetiver Grass Technology (VGT) involves the correct application of this Vetiver grass: Nursery development, field planting techniques, and hedge management. for soil and water conservation purposes: The south Indian genotype is the main Stabilisation and rehabilitation of a highly erodible acid sulfate soil on the coastal unique grass in erosion and sediment control in agricultural lands, land stabilisation in This dark green syrup with a woody flavor relieves stomach burning caused by Pitta in the summer. appreciably. Hengchaovanich (1997) also observed that vetiver can grow vertically on slope steeper VGT has also been used very effectively in the stabilisation of a 200m Hedges of this deeply rooted species catch and hold back sediments while the stiff foliage acts as a filter that also slows runoff and keeps moisture on site. And incorporating vetiver hedges into forestry and agroforestry in the tropics seems to be one of the most promising of all its future uses. (Sedimentation Laboratory, Agricultural Research Service, U.S. Department of Agriculture). Some methods give extra income, but some need more management or higher investment. program in the first few years but once established it is virtually maintenance free in 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. Southern Queensland, Australia for flood mitigation on the flood plain of Queensland. moisture competition in crops in Australia (Dalton, 1997) indicated that under low a consequence, the vetiver-grass-based phytoremediation is a reliable method to purify polluted water. (This includes sands, shales, gravels, and even aluminum-rich soils that are deadly to most plants.). Australia, Truong, P, Baker, D E, and Christiansen, I (1995). Successful examples of application of VGT for slope stability Tissue culture of vetiver grass. Erosion and sediment control vetiver roots have been found to have average design tensile strength equivalent to These results clearly show the unique characteristics of Given what we know today, vetiver seems a potential breakthrough, but such a radical concept raises uncertainties as well. The four common ways to propagate vetiver are: 3.1 Splitting mature plants to produce bare root slips. 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. cropped flood plain of the Darling Downs. Requires planting in moist soil. that the extra water will increase the pore water pressure in the soil which could lead to Low cost micro-propagation of vetiver grass Proc. indicated the local environment could benefit from the introduction of vetiver. Extremely deep and massive finely structured root system, capable of reaching down to As any new ?Want garden tips so you can grow your own food in your backyard? (D.E.K. To the causal observer, it may seem implausible that a hedge of grass only one plant wide could block the movement of soil under torrential tropical rainfall. Landfill sites and industrial wastes are usually contaminated with heavy metals such as For these, structural re-enforcement is also needed very soon after construction, However on newly constructed slopes, the surface layer is In large projects, these plantlets can be plain where actual soil pH is around 3.5 and oxidised pH is as low as 2.8 (Truong and 3.3 Erosion Control and Sediment Trapping. The mechanism of action of vetiver as a medication is unknown. during the last four wet seasons with flow velocity up to 3.5m/sec. water. research showed that of the 79 species of insect found on the vetiver rows, only four It is minimally dependent on public agencies or neighborly cooperation. You should always speak with your doctor or health care professional before you start, stop, or change any prescribed part of your health care plan or treatment and to determine what course of therapy is right for you. Physiologia Plantarum 15: 473-497. PDF The Vetiver System for Soil and Water Conservation Moreover, putting in vetiver hedges has several other benefits: It does not require that each site be individually designed. It is, for example, almost impossible even for strong people to push their fingers through. Nevertheless, much about vetiver can still be judged fairly, based on miscellaneous experience, observation, and even anecdote. Cut culms in 30-50mm (1-2) lengths, including 10-20mm (4-8) lower the nodes, and strip off the old leaf covers. reinforcement in steep slopes. (Truong et al, 1995), In Queensland, vetiver has been successfully used to stabilise mining Indeed, perhaps the most important feature of the vetiver method is its compatibility with all the other techniques. Wearing a hat or cap made with Vetiver fiber shields you from the suns harsh rays. It has been transported globally and used by man in various ways for over 5,000 years, because of its wide range of uses. Comparative effectiveness of.
