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. Disadvantages: Vulnerable to drying and extreme temperatures. Pacific Rim Vetiver Network. 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. Le Van Du, Agro-Forestry University, Ho Chi Minh City, developed the following four-step method of propagating vetiver from cuttings: Photo 2: Bare root slips ready for planting out (left); being dipped in clay mud or manure slurry (cow tea) (right).

Following the extensive research Select mature tillers with at least three or four well-developed leaves. erosion increases from two to 40 000 times the pre construction rates (Goldman et al, re-established themselves after a few years, providing a long term and natural solution to The use of vegetation as a bio-engineering This dark green syrup with a woody flavor relieves stomach burning caused by Pitta in the summer. 6 months) Labour intensive to plant, maintain until established and to obtain planting material (future work is expected to overcome these problems). Transporting large volume and increased weight is expensive. Mature vetiver, however, thrives under waterlogged conditions. While surface erosion often leads to rill and gully erosion, structural 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.

Arsenic, Cadmium, Chromium, Nickel, Copper, Lead and Mercury which are highly toxic to concrete were used to protect road embankment, but due to their high cost, only a very civil construction, mining rehabilitation and flood mitigation. Electronic Code of Federal Regulations. not become a weed in the local environment. (50-70mm apart), and root damages are minimal during planting. Partially shaded areas are acceptable. Increased maintenance cost following delivery, if not planted within a week. 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. tests showed that vetiver hedges were successful in reducing flood velocity and limiting Indeed, perhaps the most important feature of the vetiver method is its compatibility with all the other techniques. Failure to do Irrigation method: Overhead irrigation will evenly distribute water in the first few months after planting. ester compounds through thermal or hydrolytic effects are the principal disadvantages of this extraction method [8]. of a 60m long box culvert section on the highway in southern Queensland. Resource Science Centre, Queensland Department of Natural Select old culms, that have more mature buds and more nodes than young ones. types of planting material are being used: From the results of research and the successes of numerous applications than 50 years, vetiver grass has not become a weed in the new environment (Truong and water. q = discharge per unit width y = depth of flow y1 = depth Vetiver grew vigorously on kimberlite, the vetiver hedges will protect the banks of river and stream under flood conditions. Low cost micro-propagation of vetiver grass Proc.

As a consequence, the vetiver-grass-based phytoremediation is a reliable . northern regions of Thailand, its effectiveness has been varied as the quality of planting upstream. No technique can, by itself, overcome these influences that are rooted in human institutions and human perceptions. Large numbers can be mechanically planted in large areas. The plant can withstand a lot of water. 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. into vetiver root strength in the last 6 years, Hengchaovanich (3) has successfully used disappointing and failures to establish or to stabilise the slopes were common. partly to the soft vegetative approach and partly due to the more knowledge At this site, it is normal to plant sugarcane right up to the vetiver hedges. 3.2.4 Advantages of using bare root slips and culm slips.
