The Vetiver System: Proven and Green Environmental Solutions
Vetiver grass (Chrysopogon zizanioides L.) is a perennial, tropical/sub tropical grass that has been used extensively world wide for soil erosion and sediment control and steep slope stabilisation for the last 20 years. Recently vetiver has also been used successfully for mine site rehabilitation in Australia, China, Latin America and South Africa, including stabilisation of steep slopes associated with bunds, tailings dams, and revegetation of mine tailings. Important attributes of vetiver grass are highly tolerant to: 1) Extreme acidity, alkalinity, sodicity, salinity and climatic conditions; 2) Very high levels of heavy metals, pollutants and nutrients; 3) It is sterile and has no potential to become a weed. |
