The Vetiver System has many agricultural uses for: soil and water conservation, soil moisture improvement, groundwater recharge, recycling soil nutrients, pest control, mulch, forage, clean up of agricultural contaminated waste water, protection of farm infrastructure (canals, drains, roads, and building sites). The Vetiver System will reduce soil loss from farm land by as much as 90% and will reduce rainfall runoff by as much as 70%, thus significantly increasing the effective rainfall available to crops. The impact goes further - groundwater is recharged to the extent that ephemeral streams flow longer and stronger, wetlands are rejuvenated, wild life habitat is improved and soil fertility improves - resulting in increased crop yields that have been measured as much as 40%.

Vetiver grass for pest control in adjacent crops. Vetiver hosts many different insects 99% of which do no damage to the plant. On the other hand many of those hosted insects such as parastoidal wasps destroy leaf sucking insects on adjacent crops. Also vetiver is a dead end trap crop for stem borer of rice, sorgum and maize.


In South Africa's Western Cape vetiver is being grown between rows of grapes to suspress weeds (when cut as mulch - 4 times a year), conserve moisture, recycle nutients, improve organic matter, and stop and erosion. Reports from Vietnam, Spain, and Italy alsssso show benefits to grapes from vetiver planting. We have seen in Thailand and Vietnam that where perennial plants have been grown in close association with vetiver the plants develop a positive symbiotic relationship with vetiver and greatly benefit from the mychoriza activity associated with the vetiver roots and the improveement of avaaailable soil moisture.

Tulube man

"The Vetiver Man of Tulube" - a farmer from western Ethiopia who has in this year of dought obtained four times the average yield of maize using vetiver hedgerows supported by other improved crop practices. Vetiver hedgerows were key in that they enabled efficient use of rainfall and soil fertility improvements. Read the full story. A pdf file of this story can be downloaded.

Vetiver Grass - The Hedge Against Erosion: A technology for soil and water conservation and embankment stabilization

This video was first prepared in 1995 and is a voice over slide production describing how vetiver grass technology works. Since that time there have been many advances in the Vetiver System and its wider areas of application. However the basic technology remains very much the same, and the video provides a useful entry point for a new user. (28 mins)
