His Majesty King Bhumibol Adulyadej The Great first began the Vetiver Grass Project at Huai Sai, Phetchaburi Province, where samples were grown especially for the first experiment.

Initial results indicated the Vetiver grass had taken strong root in the soil and its surface foliage was also sufficiently strong and dense to act as a harrier, well able to resist flowing water. Many organizations cooperated together to help develop and promote the Vetiver Grass Project in accordance with his aspirations.

In 1993. by unanimous agreement, the International Erosion Control Association ( IECA) presented the International Erosion Control Association's International Merit Award to His Majesty King Bhumibol Adulyadej The Great for his outstanding leadership in adapting Vetiver Grass for soil, water, and environmental conservation.

In the same year the World Bank presented a Bronze-plate featuring a Vetiver Grass Sculpture as an Award to His Majesty King Bhumibol Adulyadej The Great, praising His Majesty's role as a major soil and water conservationist
