Vetiver for Land Restoration

Friday, January 8, 2016

Liyu Xu, Vetiver Coordinator for China, has been promoting the Vetiver System for 20 years, and continues to provide us with feedback on the use of vetiver in south China. Most of the areas that he personally is involved with are relatively high rainfall and hilly areas where soil is poor and where people are poor. In Yunnan province a group of farmers have formed a cooperative to support the production of cattle and goats using vetiver as the main source of feed. Liyu's note is at: http://www.vetiver.org/CHN_cooperative%20of%20raising%20cattle.pdf and is well worth reading. The bottom line is that when grown as a forage, and managed and fed on a rotational cutting system at a time when the vetiver leaf is young it is possible to get good growth and substantial increase in incomes. It is interesting that these farmers also sell some of their vetiver as plant material to local construction companies for slope stabilization and other purposes. In addition on farm erosion and rainfall runoff is reduced. Seems to be a WIN WIN situation!!
I have been writing about the potential of these multipurpose applications of vetiver for a number of years now. This one from Yunnan is a good example. Vetiver is grown and managed (not just as a hedge) as a forage crop supporting in this case 3 head of cattle/ha; it is cut as forage every two or three weeks (at larger scale it could be strip grazed); some of it is being harvested and sold as planting material; it is drought tolerant, it grows with minimum inputs, and is protecting and enhancing the soil. The cow manure will either be used for biogas production or returned to the land. The cooperativer structure is interesting, quote "The cooperative operates as a combination of company, cooperative, and farmers. The Yunnan Vetiver Sci-Tech Co. Ltd, a branch company of Kunming Guangbao Biotechnology
Engineering Co. Ltd is a shareholder in the form of technical service, seedling
supply, and Vetiver plant material repurchase; the cooperative distributes seedlings to farmers in terms of
individual need; and the farmers individually cultivate the Vetiver. Worth trying in other countries????Dick Grimshaw
