Newsletter – Vetiver Secrets, Soil Health, Wastewater, Forage (NL 2025-01)

The Secrets of Vetiver. As research is carried out on various attributes and applications of vetiver we are coming to learn how the plant functions and what it can do. A recent Chinese study “Reshaping the microenvironment and bacterial community of TNT- and RDX-contaminated soil by combined remediation with vetiver grass (Vetiveria ziznioides) and effective microorganism (EM) flora“ The degradation rates of TNT and RDX after 60 days of combined remediation were 95.66% and 84.37%, respectively.… Read the rest “Newsletter – Vetiver Secrets, Soil Health, Wastewater, Forage (NL 2025-01)”

Newsletter – The Vetiver System in 2024 (NL 2024-12)

The Vetiver System in 2024 As we come to the end of 2024 – which marked about 40 years since John Greenfield and Dick Grimshaw began to explore the use of Vetiver grass as an alternative to structural soil and moisture conservation practices in India – it is deeply satisfying to see that, by all appearances, not only has interest in the Vetiver System continued to expand globally, but that the use of VS has continued to gain traction as a sustainable and effective approach for addressing a wide range of environmental challenges around the globe.… Read the rest “Newsletter – The Vetiver System in 2024 (NL 2024-12)”

Slope Stabilization and Land Restoration (mining) in China

Feng Ziyuan who owns and manages the oldest vetiver service company in China (more than 20 years) has been a serious contributor to the advancement of the Vetiver System. He sets high standards resulting in above average VS applications, and he has been generous in sharing his results. This short presentation “Vetiver System Technology Application” that he made recently relates to his slope stabilization, mine, and gully restoration applications . Feng is also involved with the deign and execution of phytoremedial applications of vetiver for the treatment of waste and other contaminated water.… Read the rest “Slope Stabilization and Land Restoration (mining) in China”

Newsletter – Vetiver and Youth, Bio-engineering, Wastewater Treatment, Global Feedback (NL 2024-11)

This newsletter addresses Vetiver and youth, global outreach, feedback from users, and research news. Sharing experiences and information. The more this group and other vetiver users share their experiences the more people will use the technology. I see this happening in many countries and regions, recently especially in Latin America, India, Kenya, and Vietnam.   Key users, often with different approaches, are making real progress and creating interest for others. Sharing/information sources of current note include: the monthly webinar series “Conversatorio” hosted by Yorlene Cruz (Coordinator of the Costa Rica and member of Latin Vetiver Networks) are posted on TVNI’s Youtube channel;  the new Facebook page – Vetiver in Kenya – attracts a growing readership;  India’s Agricultural World Whatsapp, AW#VETIVER forum,  focusing on “all things vetiver” is expanding and contains lively discussion on a range of vetiver topics and applications.… Read the rest “Newsletter – Vetiver and Youth, Bio-engineering, Wastewater Treatment, Global Feedback (NL 2024-11)”

Black Cotton Soils (Vertisols) and the Vetiver System

What follows is a reprint of a note by the late John Greenfield on conservation practices for black cotton soils (vertisols) – It should be an interest too many of you.   I was faced with the problems of managing black cotton soils in the early 50s in Australia while working with the Soil Conservation Service. Overnight, a heavy storm had wiped out a large area of a farmers wheat crop and fence line leaving gullies several meters deep.… Read the rest “Black Cotton Soils (Vertisols) and the Vetiver System”
