Coal Flyash Dump Successfully Stabilized with Vetiver Grass

When not stabilized and protected, fly ash dumps, associated with coal fired power generation plants, are serious health hazards due to heavy metals (Zn, Pb, Cu, Ni, Cd, and As) in the fly ash dust and associated dumpsite leachates. These toxic chemicals impact surrounding people, animals, land and groundwater. Phytoremedial mitigation using vetiver grass can be very effective, primarily through phytostabilization of the fly ash, with phytoextraction of toxic metals as a secondary benefit.  Vetiver when grown in fly ash: has a dense mass of ash binding roots; is tolerant to the heavy metals (that when extracted remain mainly in the roots — the leaves can be fed safely to livestock or used for other purposes); and shows no significant sign of plant damage thus assuring long term survival.  … Read the rest “Coal Flyash Dump Successfully Stabilized with Vetiver Grass”

China – Vetiver Research and Development

China – Vetiver Research and Development. Recently Liyu Xu, China Vetiver Network Coordinator, sent me the digital text (in English) of a book published in 2003 relating to the title of this post. It contains useful information and data from 1988 to 2003 – a period when there was a lot of vetiver activity following the introduction of the Vetiver System to the World Bank funded Red Soils Project located in Jiangxi and Fujian Province in 1988.… Read the rest “China – Vetiver Research and Development”

Vetiver Roots – The Hidden Half.

  This new book by Dr. Paul Truong provides a wealth of information on the function and unique role of the roots of vetiver grass that allow for a wide range of environmental mitigation. Paul Truong, TVNI’s Technical Director, has been undertaking research and development of Vetiver System Technology (VST). He was fortunate to be located in Queensland, Australia, allowing him to research and apply a wide range of VST applications, under many different climatic and ecological conditions.… Read the rest “Vetiver Roots – The Hidden Half.”

“RIDGE TO REEF – A CRITICAL ROLE FOR VETIVER GRASS” – A QUICK FIX?

The tropical island watershed conservation “Ridge to Reef” concept is a popular strategy for reducing soil erosion and sediment/pollutant movement from the upper watersheds to populated coastal areas and in-shore waters. Ridge to Reef programs could be accelerated and be more effective if Vetiver Grass Technology (VGT) was applied more widely and through community initiative.
