Vetiver could be used as an integrated technique for environmental management of mining activities. First, solid mining wastes could be stabilized not to release to surroundings. Second, wastewater including acid mine drainage (AMD) could be purified by phytofiltration. Third, the surrounding lands contaminated by heavy metals could be cleaned up by phytoextraction.
Entomologist Johnnie van den Berg (Potchefstroom University, South Africa) found that larvae prefer to lay eggs on vetiver leaves planted around the crop instead of on the maize or rice crop itself. Vetiver leaves are hairy, the larvae that hatch on them cannot move around easily, resulting in about 90% of the eggs are dead. Vetiver also harbors many helpful insects that are predators of pests that attack crops.
Objectives of Vetiver hedgerows include reducing soil erosion, preserving plant nutrient, maintaining soil organic matter, stabilizing soil chemical and physical properties, and storing water in soil. Appropriate use of land or soil and water resources with wise and economic could preserve soil fertility for the highest yield and sustainability.
Deforested land area is degraded mostly because of the topsoil being washed away by water runoff. In Thailand, upland farming with contour planting of vetiver strips can increase crop yield by 20%, decrease runoff by 50%, and erosion by 70%. This paper shows some research results of demonstrations on farming households’ lands in Vietnam.
Soil nailing is commonly implemented to strengthen the weak structure of the soil on the very steep slopes. However, soil nailing does not provide protection against surface erosion on these slopes. Application of Vetiver bioengineering is a perfect compliment for controlling the surface erosion problem of soil nailing. The slides demonstrate this complementary effect in Medellin, Colombia, and Vietnam.
Vetiver System has been established for dike stabilization, erosion and sediment control, and water quality improvement by treating uneaten food and feces. The slides demonstrate this application in a Basa farm near Can Tho City of Vietnam.
In the afternoon of the same day, a seminar on “Vetiver System: Empowering Sustainable Development” was held in Danang Administrative Center. During the Seminar, Vetiver experts presented keynote speeches, including applications of the Vetiver System: A review and update from the world to Vietnam and Danang, Notices in the research and application of Vetiver in Vietnam’s Central, and Ways to empower farmers and Vetiver planters for extra income. The Seminar […]
1. Benefits of Vetiver Essential Oil 1.1. ADHD Management Essential oils are portable, easy to use, and can be effective for relieving symptoms of ADHD and helping kids (or adults!) to focus. This simply studies only asked parents to help their children smell the oil right from the bottle a few times each day. Parents reported better attention and behavior from their children during the study period. 1.2. Anxiety Control […]
Potential application of Vetiver for remidiation of agent orange/dioxin contaminated soils at BienHoa Airbase
Project Manager: Dr.Ngo Thi Thuy Huong _ The VietNam Institute of Geosciences and Mineral Resources (VIGMR) The results shows that Vetiver – Monto ecotype could grow well and normally on soil polluted by Dioxin and Dioxin-Like Compounds in light and medium levels. The growth monitoring data indicated that the best growth period of Vetiver was eight months after planted when the stems reached up to 2.5 m, over 30 new […]
How to set up a wetland model with Vetiver: 1. Substrate and Collection Tanks 2. Filter Layers Large broken stones Small broken stones Small gravel layer Sand layer 3. Vetiver Plantation – Wastewater is led into the system through the distribution pipelines – Keep pumping until the ground is flooded – Leave Vetiver 2 hours to treat – […]
