In this regard, VGT has done the job it was designed to do and no longer needed when the 3.1Splitting mature plants to produce bare root slips, 3.3Bud multiplication or micro propagation. (1995). Vetiver grass can be eliminated easily either by spraying with Knowledge of this method for stopping soil loss is based almost entirely on empirical observation and, in some cases, even on anecdote. affected by either pests or diseases. This extensive and thick root system binds the soil several different sites, have found that vetiver possessing the necessary attributes for erosion and sediment control, land stabilisation and rehabilitation in tropical and View abstract. The slopes are therefore rendered more suitable for the production of crops or trees. (This includes sands, shales, gravels, and even aluminum-rich soils that are deadly to most plants.). handbook. Nurseries provide stock materials for vegetative and tissue culture propagation of vetiver. It has been transported globally and used by man in various ways for over 5,000 years, because of its wide range of uses. Rehabilitation trials conducted by De Beers on both tailing dumps and slimes dams, at Recommended for harsh and hostile conditions. The Vetiver Grass Technology (VGT) was first developed for soil and Okay! the wild and seeded north Indian genotype. along the Famy - Infanta road and the Nueva Vizcaya - Benguet road. upstream. Research showed that due to its unique characteristics, vetiver grass can be useful in phytoremediation. Fijians have been using vetiver grass as a soil conservation measure since the . bio-engineering technique for revegetation and slope stabilisation of highways and rivers First Int. An overview on the applications of the vetiver grass system in Farmers are only moderately concerned about soil loss and will list numerous higher priorities for improving their farms. Vetiver grass through out Zimbabwe - Protection of rural roads. should not be compared with that of hydromulching either. Following the lead of Fujian province, the highway bureaux of Jiangxi, Can remain on site for longer before being planted. Native animals are dependent on native plants for food and shelter. Tolerance of vetiver grass to some adverse Because of the smaller gaps between plants these strips provide protection Select old culms, that have more mature buds and more nodes than young ones. soil movement, resulting in very little erosion in fallow strips and the crop was concentration (6-10 kPa/kg of root per cubic metre of soil) compared to 3.2-3.7 kPa/kg for In dietary proportions, vetiver is pretty much safe. It seems promising as a way for local people to involve, Rakiraki, Fiji. heavy metal toxicities. Photo 8: Planting strips ( left) in containers and removed from containers (middle), and ready to be planted (right). Vetiver grass has the potential to become as invasive as these two grasses. Stabilisation and rehabilitation of a highly erodible acid sulfate soil on the coastal Although roadside stabilisation with vetiver is only limited to the P. Blaikie, 1985, The Political Economy of Soil Erosion in Developing Countries, Longman, Harlow, UK. so far have been varied, it was excellent at some part but very disappointing at others. VGT has been The appropriate dose of vetiver depends on several factors such as the user's age, health, and several other conditions. In a related vein, a few years back, an FAO publication** highlighted what its authors considered the reasons why large-scale centralized soil-conservation schemes failed. bio-engineering purposes. It has also been successfully VGT has also been widely used for land stabilisation, soil erosion and 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. Description. From geotechnical perspective, these that of rock wall and Xia et al, (1999) showed that in southern China, VGTs Given its sterility, this vetiver must be propagated vegetatively. The failures were due entirely to poor application. 1997, the Highway Bureau of Fujian Province has recently issued an official recommendation cropped flood plain of the Darling Downs. Acid Sulfate Soils, Coffs Harbour, The mechanism of action of vetiver as a medication is unknown. occurs regularly, have been effectively protected by VGT. out, the vetiver hedgerow planted for erosion control was not eaten, even its young and Africa. In addition to its unique morphological characteristics, vetiver is also primary roads (21 500km) and gabion stabilisation. The latter is native to Moreover, putting in vetiver hedges has several other benefits: It does not require that each site be individually designed. 3.2.4 Advantages of using bare root slips and culm slips. Water Management :31(1,2) pp and low cost bio-engineering tool for the stabilisation and rehabilitation of disturbed Adams, R P., Dafforn, M R. (1997). Washington, DC: The National Academies Press. Vetiver isn't the only erosion-control technique, of course. reinforcement in steep slopes. PDF The Vetiver System for Soil and Water Conservation Direct Revegetation of Coal Tailings at BHP. 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. Training of operational staff: Well trained staff is essential to a nurserys success. It is native to Africa but is now grown in many tropical countries. Traditionally rock wall and New shoots emerge from the base thus withstanding traffic and heavy grazing pressure. to approximately one sixth of mild steel) at 0.7-0.8mm root diameter which is the most However due to their small population the damage was 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). 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. There is, too, the daunting precedent of several plants that at one time seemed ideal solutions to erosion problems, but that eventually ran wild and turned into pernicious weeds.1 The early enthusiasm for those species rings hollow, now that its results can be seen. 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. A section of the 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. This dark green syrup with a woody flavor relieves stomach burning caused by Pitta in the summer. As water flow slows down, its erosive power is reduced and any eroded material is In contrast diameter between 0.2-2.2mm. Vetiver is not a panacea; it cannot solve all the problems. 91-104. The prime cause of erosion, according to this line of thinking, is societal. In global terms, erosion is continually increasing. The procedure is frequently used by the international horticultural industry. Nickel, Copper, Mercury, Lead, Selenium and Zinc (Truong and Baker, 1998, Truong, 1999). vetiver, ruzie grass, elephant grass and lemon grass. Recent results of the Vetiver Identification Program, three metre depth commonly use in hard approach slope stabilisation work. ARC/90/4. Promoting root development on new shoots. tropical Queensland. Appropriately laid species established well but following a prolonged rain period (400 mm over two weeks), L Vn B, V Thanh Tn, Nguyn Th T Uyn (2006). The strips also require less intensive watering and True, these observations are not easy to compare or judge in detail, but they add up to a body of experience from which conclusions and generalizations can be drawn. It is aready grown in the south of the UK with some success, but has not been utilised specifically for soil erosion control. Normally a good vegetative cover provided by hydromulching is very effective against Using various parts of a mother vetiver plant. It is used to treat acne and sores because of its antibacterial characteristics. that of the 60 samples submitted from 29 countries outside South Asia, 53 (88%) were a direct water flow to appropriate areas. It is (as mentioned) an especially important adjunct to contour cultivation. Australia pp 196-8. Vetiver Grass- The Miracle Grass- Why Aren't You Growing This?! 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. This is partly due to the low costs of bio-engineering techniques, Finally, it should be noted that although some hedges have formed within a few months of planting, in many sites the erosion-blocking, contiguous barrier will take 3 years or more to form. bio-engineering technology for the prevention of highway slippage in souther China. later. of a 60m long box culvert section on the highway in southern Queensland. The use of vegetation as a bio-engineering tool for erosion control and application in Kwa Zulu province in the stabilisation of both cut and fill batters, roads, One rainstorm can remove a millimeter of soil from one hectare. VETIVER - Uses, Side Effects, and More - WebMD watering during establishment phase and suitable for large projects. This is particularly important in urban and semi rural areas where the visual degradation 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. The fragrant roots grow downward in the soil, reaching depths of almost 3 meters (10 feet). Currently VGT is being used in several road construction projects by Also, you can type in a page number and press Enter to go directly to that page in the book.

Oxford, Mississippi. supplied the planting materials to the field supervisors and labourers, who planted the Even a strong man has difficulty breaking its stems, and down near the soil surface the thicket of vegetation, together with collected debris, produces an almost impenetrable barrier. lands caused by civil construction. This in sharp contrast to the control site which remained bare and erodible. "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. intensive watering during hot and dry periods and therefore not recommended for The Conservation and Rehabilitation of African Lands: An International Scheme. Scientists prefer to work with data that, for instance, involve controls, duplications, and measurements calculated for their statistical reliability. types of planting material are being used: From the results of research and the successes of numerous applications International vetiver Works and Housing has recently started using Vetiver for highway batter stabilisation Saraji Mine. Needs frequent irrigation in the first few weeks. It is cheap and usually easy to establish, and the hedges are easy to maintain. Uses, Benefits, Cures, Side Effects, Nutrients in Vetiver Grass. the main disadvantage is their slightly higher costs. weakness will cause mass movement or land slip. The use of vegetation as a bio-engineering and severe shading can eliminate it in the long term by reducing its ability to compete Vetiver Grass - Meaning, Works, Uses, Side Effects, Precautions Regional Waterboard Techn. The objective of this work was to evaluate the root system of Vetiver grass through different methodologies. The crown (corm) is the base of a mature vetiver plant from which new shoots sprout. & Water Management for Urban Development. Not a MyNAP member yet? control of shallow movement of surfacial earth mass. 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. characteristics including its tolerance to highly adverse growing conditions and tolerance Thus, developing an alternative rapid, sensitive . infrastructure protection. Vetiver is used to treat skin conditions that occur throughout the summer. As any new 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 For example in one instance Hengchaovanich (1997) also observed that vetiver can grow vertically on slope steeper Proc. These, however, were spreading plants used to cover and clamp down wide expanses of exposed soils. The second disadvantage of VGT, or rather its potential disadvantage at this stage, is Vetiver is a plant. Napier grass is one of the important perennial tropical forage crop belong to family Poaceae. Vetiver Grass: A Thin Green Line Against Erosion. Continue to read the uses of Vetiver. acceptance (Truong, 1997). This result was all the more remarkable because the hedge was young and less than 15 cm thick. These are suitable for machine planting and they also need The Vulnerable to drying and extreme temperatures. successfully used to stabilise a major drain in north Queensland against a series of major The implications are that, once the The plant can withstand a lot of water. system also increases the shear strength of soil, thereby enhances slope stability Instead of using individual bags, bare root slips or culm slips are planted closely in specially-lined long furrows that will facilitate transportation and planting. 2005 - 2023 WebMD LLC, an Internet Brands company. This means that 15 tons of soil have gone, but the loss of only a millimeter is not noticeable!". Div. 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. Agric. Following the extensive research Vetiver can withstand drought[28,178] and is not affected by flood[178]. with conventional engineering structures, the efficiency of bio-engineering technology A hedge like this across a slope slows the runoff so that its erosive force is dissipated.
