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%.

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. Unofficially the wine is great with a subtle flavor. We will publish an official report from the wine taster later. The vines look very healthy too. Wine producers in Australia, California and the Mediterranean countries might also be interested in this application. We have seen in Thailand that where perennial plants have been grown in close association with vetiver that the plants develop a positive symbiotic relationship with vetiver and greatly benefit from the mychoriza activity associated with the vetiver roots.

"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 System for Soil Erosion Control in Ethiopia. A slide show put together by Alemu Mekonnen in 2000 gives quite a good idea of the soil erosion and soil loss that Ethiopian farmers are faced with, and how the Vetiver System can help mitigate the problems. Since 2000 VS applications have extended to many other parts of the country. A paper describing this work provides a good background this slide show. |
