Vetiver Grass an Eco Friendly Solution to Geo Synthetical Problems. This Grass help Prevents the Soil Erosion. A Herb, which grows up to a height of 5ft above the ground and reaches a root length of 4mts in a span of 3 years.
What is Vetiver?
A Herb, which grows up to a height of 5ft above the ground and reaches a root length of 4mts in a span of 3 years.
Vetiver grass is the key element in a low cost and efficient system, for soil and water conservation, infrastructure stabilization, pollution control, waste water treatment, mitigation and rehabilitation, sediment control, prevention of storm damage and many other environmental protection applications.
This grass is the main component to all Vetiver System bioengineering and conservation applications. The plant is unique. It can be used in the tropics and semi tropics, and areas that have a Mediterranean type climate where there are hot summers, and winters are temperate.
Following are the applications of VETIVER :
Although many grasses and trees have been tried over the years as measures to prevent erosion, to date only Vetiver grass has stood out.
How it Works?
Vetiver grass slip, approximately 2 m high, with a solid thick and primarily upright base system regularly estimating more than 3 m. In addition, it is through quality a hydrophyte, yet sometimes flourishes under xerophytic environs.
Vetiver grass slip develops better under damp environs, yet does well additionally under less dampness.
Hard to set up under shade, when it is expelled development recuperation is quick.
Develops best on profound sandy loam soils. But, it will develop on most soil sorts varying from dark splitting vertisols over to red alfisols. Vetiver grass slip will develop on rubble, both alkali (pH11) as well as acid (ph3) soils, it is retardant to elevated amounts of mineral cytotoxicity - manganese (550 ppm) and aluminum. Further, it will endure intact submergence in water for around five months. It develops on both deep and shallow soils.
Up to around 2,000 m. Over 2000 m development of Vetiver grass slip can be inhibited by minimum temperatures.
1-1.5% of parched load of the roots, which are reaped for refining
Matured levels under moist (irrigated) and fertile environs may be as elevated as 2,00,000 pounds for every ha. Generally 30,000 - 60,000 pounds/ha.
Diseases and Pests:
Vetiver grass slip is normally impervious to most diseases and pest. It looks to be more receptive to illness, when it is not growing well and weak, specifically on extremely superficial soils in relation with drought environs. Under the last environs, root parasite strikes may be critical.
Termites will just strike dying or dead sections of vetiver. If the strike is critical on Vetiver grass slip, the termite "slopes" made can cover living vetiver grass slip. Under such environs yearly blazing of vetiver hedges will enormously decrease the rate of termite harm because of wear out of dead plant material. Further, then again late research demonstrates that Vetiver has great ability like a "push pull" crop, captivating insects like stem borer far from contiguous maize crops.
Vetiver grass slip is acknowledged to live for a prolonged period. The longest transcribed period is around 60 years (at Msamfu Research Station in Zambia).
