us applications in erosion and sediment control. VS was first developed by the World Bank for soil and water conservation in India in the 1980s. Research and development conducted in Queensland and overseas since then have also shown VS to be very effective in:
• Water erosion control in agricultural lands such as flood erosion control, contour bank substitution and in gully stabilization.
• Erosion and sediment control on steep slopes as a bioengineering technique. It has been used successfully for steep outer batter slopes on dams.
• Mine rehabilitation, Vetiver grass is highly tolerant to heavy metals as well as to extreme edaphic and climatic conditions. Vetiver roots have a tufted vertically growing root structure. The roots are one of the most important organizational systems that make Vetiver a MIRACLE GRASS for its multifarious applications in soil and water conservation, soil health, and raw material for Vetiver root handicrafts, environmental and perfumery products. A lot of fiversity is found in the Vetiver root system in nature, and a search for root morphology and geometry could lead to a desired root type. Vetiver grass is a plant with deep-root system penetrating straight into the soil and spreading like an underground barrier capable of filtering sediments and protecting the soil surface from runoff, but it is incapable of propagating itself by seed. It is a perennial densely tufted grass found throughout tropical and subtropical plains and lower hills, particularly along riverbanks and over marshy land. Its is ideal for soil and moisture conservation, and to prevent the worsening of the environment. Gravity-guided penetrative and branching property of roots that enables soil and rocky substrates to be explored and in a steadily expanding way that keeps in proportion to the aerial root system it supports, physically for stability and chemically for metabolic and reproductive ongoing, makes the root as the lifeline of plant machinery. Thus, in a true perspective roots are the most vital components strongly in contrast with their modest outward appearance just as physical support axes. Vetiver is a suitable case since its roots system is an important organ having value for commercial and environmental applications. Most grasses have fibrous roots, which spread out from the underground part of the culm and hold the soil in a horizontal pattern. The vetiver roots, however, penetrate vertically into the soil, whether it is the main root, secondary root or the fibrous ramification.
