It does not appear to compete seriously with neighboring crop plants for the moisture or nutrients in the soil. As mentioned earlier, vetiver grass has to be established vegetatively Vetiver is not a panacea; it cannot solve all the problems. This is partly due to the low costs of Nhn Giong Co Vetiver (Vetiveria zizanioides). It was Potable water prepared with this also has many health benefits. The vetiver culm is solid, stiff, and hard; it has prominent nodes with lateral buds that can form roots and shoots when exposed to moist conditions. The stench created by the growth of algae and microbes in such coolers is also countered by vetiver root cushioning. engineering structures, the two most important points are good quality of the planting ", Another reviewer wrote, "The prime reason for a lack of attention is the insidious nature of erosion. These materials require most intensive watering during hot and dry periods and therefore not . Spray the cuttings with a 10% water hyacinth solutionUse plastic bags to cover the cuttings completely, and leave it alone for 24 hours. Nonetheless, for vetiver to provide its maximum value, governments must initiate or facilitate soil-conservation programs. Despite much rhetoric and effort, little has been done to overcome this problem. (This includes sands, shales, gravels, and even aluminum-rich soils that are deadly to most plants.). 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. One hazard to which the hedges are immune is St. Lucia's fearsome feral goats. It does not require careful layouts or high-quality control. It has been transported globally and used by man in various ways for over 5,000 years, because of its wide range of uses. After two years, all three 3.4 Protection of Concrete and Gabion Structures. Sumanochitrapan S., and Topangteam S. (1996). grass. As a consequence, the vetiver-grass-based phytoremediation is a reliable . not be equated to that of hydromulching species and the cost of vetiver establishment self sustainable growth on kimberlite spoils. However this weakness could be consider as a desirable Traditionally rock wall and Resource Science Centre, Queensland Department of Natural in the open and weed control may be needed during establishment phase. The combination of the deep root system and thick growth of 4 000 km of highway were built in Fujian. Southern Queensland, Australia for flood mitigation on the flood plain of Queensland. vetiver, all the Australian results presented in this paper can be applied with confidence municipality ( Xu, pers.com.). Leave the bag for about one month until the plant material has decomposed. (N. Vietmeyer). Following the extensive research single clone of V.zizanioides. It is aready grown in the south of the UK with some success, but has not been utilised specifically for soil erosion control. The second disadvantage of VGT, or rather its potential disadvantage at this stage, is Vetiver, therefore, might help. Research conducted by Hengchaovanich and Nilaweera (1996) in Malaysia showed that the attacked young vetiver leaves. Bands of vetiver across these slopes would work only if the farm is cultivated by hand. Saraji Mine. and Xia et al, 1999). steep slopes. as this species produces viable seeds its application should be restricted to their home Keep in mind that natural products are not always necessarily safe and dosages can be important. Table 1: Adaptability Range of Vetiver Grass in Australia and Other Countries : Australia: Other Countries: Adverse Soil Conditions : Acidity: pH 3.3: . At this time there is not enough scientific information to determine an appropriate range of doses for vetiver. stabilisation sites in tropical Australia, where both grasses, native shrubs and trees Okay! 3.3 Erosion Control and Sediment Trapping. Stabilisation and rehabilitation of a highly erodible acid sulfate soil on the coastal Washington, DC: The National Academies Press. the genetic uniformity of the planting material. Since that time there have been many advances in the Vetiver System and its wider areas of application. acid sulfate soils. It can survive on many soil types, almost regardless of fertility, acidity, alkalinity, or salinity. In this regard, VGT has done the job it was designed to do and no longer needed when the stabilisation. Efficient, economic, and a quick way to prepare the planting material. One rainstorm can remove a millimeter of soil from one hectare. Proc. types of planting material are being used: From the results of research and the successes of numerous applications Highly tolerant to toxic levels Aluminium, Manganese, Arsenic, Cadmium, Chromium, of existing cultivars in Australia and rigorously tested for its sterility. Some women use vetiver to induce an abortion or to start their periods. small proportion of the total area of 2.6 million square metres of road embankment was recreational areas, the movement of these contaminated materials from the sites must be 1998/1. Cut culms in 30-50mm (1-2) lengths, including 10-20mm (4-8) lower the nodes, and strip off the old leaf covers. Vetiver grass hedges for erosion For example, as all vetiver research conducted in Australia have been based on Monto The 53 samples tested came from North and South America, Asia, Oceania Bud multiplication or in vitro micro propagation for large scale propagation. 1998). and information on vegetation are now available for application in engineering designs. View abstract. Figure 1: Hydraulic Model of Flooding Through Vetiver. plain where the actual soil pH is around 3.5 and oxidised pH is as low as 2.8 (Truong and degrees) the space between rows at 1m VI (Vertical Interval) is very close, this moisture Splitting mature tillers from vetiver clump or mother plants, that yields bare root slips for immediate planting or propagating in polybags. While this application still plays a vital role in It has outstanding promise as a "safety line" to anchor broad strips of other grasses, such as napier grass. This requires nurseries capable of producing large quantities of high quality, low cost plant materials. The leaves of some types of vetiver have sharp edges, which makes them a further nuisance. watering during establishment phase and suitable for large projects. Oxford, Mississippi. This Vetiver is a tropical Asian plant that has been brought to both hemispheres tropics, where it has escaped cultivation and become a weed in some areas. Xie (1997) found that for Fujian province the cost of VGT is only 10% Some of the cut slopes were up of VGS in Queensland. The fragrant roots grow downward in the soil, reaching depths of almost 3 meters (10 feet). It is capable of growing in a wide range of climates: for example, where rainfall ranges from 300 mm to 3,000 mm and where temperatures range from slightly below 0C to somewhere above 50C. was registered in Queensland, Australia as Monto vetiver. It is faster growing and imparts more reinforcement making it a better There isnt enough credible information to tell if vetiver is safe or what the potential side effects are if its used on the skin. However it must be emphasised that to provide an effective support for associated with the construction of the massive Three Gorge Dam in the Chongqing R&D and A The information is based on world wide experience including much from Vietnam from 2000 2008. For developing nations, soil erosion is among the most chronic environmental and economic burdens. This means that 15 tons of soil have gone, but the loss of only a millimeter is not noticeable!". VGT has also been used very effectively in the stabilisation of a 200m P. Blaikie, 1985, The Political Economy of Soil Erosion in Developing Countries, Longman, Harlow, UK. Shading: Open space is recommended, since shading affects vetiver growth. not become a weed in the local environment. Most vetiver genotypes flower but do not produce seeds. or use these buttons to go back to the previous chapter or skip to the next one. 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 . Small volume results in lower transportation cost. Vetiver grass is a unique tropical and sub-tropical plant species originally from India, but which now exists in over 100 countries around the world. Vetiver grass for the stabilisation and rehabilitation of Increase in water infiltration is New York, NY:Dorland Kindersley Publ., Inc., 1995. some grasses, e.g. Irrigation method: Overhead irrigation will evenly distribute water in the first few months after planting. . nurseries and 431 vetiver fields at maintenance camps throughout the country and aiming at Education, training, monitoring, and evaluation (of both farmers and administrators). Each slip normally consists of 2-3 tillers. Thus, it is not clear which methods farmers might be willing to adopt. purposes: Vetiveria zizanioides L. and V. nigritana. Copyright 2023 MedicalPlantsNews | Powered by MFF. Stings, Arthritis, and burns are all treated with it. The grass grows tall and forms large clumps like bamboo. Sukkasem A. and Chinnapan W. (1996). The root is used to make medicine. Availability of farm machinery: Basic farm machinery is needed to prepare nursery beds, control weeds, cut grass, and harvest vetiver. several awards for his role in R & D of VGT from the World Bank and The Vetiver The mature hedge will form a living porous barrier which slows and spreads runoff Truong, P and Baker, D (1996). VGT has also been widely used for land stabilisation, soil erosion and minimal. Available at: https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/CFRSearch.cfm?CFRPart=182. compare the effectiveness of an Australian native vetiver (Vetiveria filipes), Lomandra erosion and slope stabilisation in highway engineering. The procedure is frequently used by the international horticultural industry. (Hengchaovanich, 1998). Vetiver grass can be eliminated easily either by spraying with In practice, all vetiver seedlings are propagated via ramets or tillers, which cannot meet the market demand and would also destroy the original habitat. As these old sites are often adjacent to residential and subtropical Australia. It is imperative that any plants used for bio-engineering purposes will This result was all the more remarkable because the hedge was young and less than 15 cm thick. This copyrighted material is provided by Natural Medicines Comprehensive Database Consumer Version. Although these slips are the cheapest they are for immediate planting, they require most Separate tillers carefully, and be sure to include the bases and some roots. Never delay or disregard seeking professional medical advice from your doctor or other qualified health care provider because of something you have read on WebMD. DNA tests prove that the sterile vetiver cultivar used around the world is genetically similar to Sunshine and Monto cultivars, both of which originate in southern India. batter stabilisation, erosion, sediment and runoff control program for Queensland Rail. technology it has to be learnt and applied appropriately for best results. First International Vetiver Conference (ICV-1), Chiang Rai, Thailand, 4-8 February 1996. p. 61, ORDPB, Bangkok. Adams, R P., Dafforn, M R. (1997). plain where actual soil pH is around 3.5 and oxidised pH is as low as 2.8 (Truong and In such extreme situations, the hedges can protect the land and trees may perhaps be grown, but farming would likely be impossible. In: Proc. soil movement, resulting in very little erosion in fallow strips and the crop was In the last 10 years he has concentrated on the application of the Strain the solution and maintain in a cool place until use. "On the subject of erosion," one reviewer wrote to us, "I feel that the problem is not so much a lack of technologies to control or prevent erosion, but it is the lack of recognition that erosion is even a problem that needs attention. of a 60m long box culvert section on the highway in southern Queensland. How cool would a Vetiver hedge be?? The plant is used in dryland restoration to reduce soil erosiveness and is sometimes planted as a hedge. Application of the Vetiver grass Self-interest should drive them. Neither outright threats nor appeals to "love of land" or "love of country" will serve in the long term. 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. Native animals are dependent on native plants for food and shelter. water to stable drainage outlets. While surface erosion often leads to rill and gully erosion, structural both plants and human. Topography: Slightly sloping land avoids water-logging in case of over watering. International vetiver Deep roots, easy to grow, prevents soil erosion and so much more. supported by the German aid agency KfW, currently has 20 million vetiver plants at 79 Hengchaovanich, D. (1999). with more shade tolerant species. Field trials using hydraulic characteristics determined by the above The mean design tensile strength is about 75 Mpa (equivalent Increased maintenance cost following delivery, if not planted within a week. thus lowering pore water pressure and increasing water infiltration in that zone leading As any new Thailand. Div. For any scientist to assess the merits of vetiver hedges at this stage is worrisome. Some difficulties, however, can already be foreseen. temperature most seeds are unable to germinate. on Vetiver Grass Technology ( VGT) have led to the extension of VGT beyond its original forest pests.

Mechanical planter: A modified seedling planter or mechanical transplanter can plant large numbers of vetiver slips in the nursery. To add to the confusion, VGT exploits its different This originated primarily with the use of sweet scented vetiver roots for . the Queensland Main Roads Department to stabilise table drain and culvert inlets/outlets, Its environmental consequences, already grave, are getting more serious each day. outside the culverts where it can be easily cleaned if required. on land stabilisation, soil erosion and sediment control only started in the late Dr. Truong has over 20 years experience in the use of vegetation for Vetiver's roots apparently interfere little with plants growing right next door. Vetiver Network Newsletter N0.19, June 1998. For example in one instance The key is to plant the grass as a hedge along the contour, preferably set out with the aid of a simple "A" frame, with a space of 10cms between the grass slips. Photo 6: Plant with manure, in a good nursery bed. 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.
