The real causes of land misusesuch as the land tenure systemare never analyzed. Moreover, putting in vetiver hedges has several other benefits: It does not require that each site be individually designed. The prime cause of erosion, according to this line of thinking, is societal. stronger than that of many hardwood species which have been proven positive for root and massive root system it offers better shear strength increase per unit fibre Thailand. this effect has to be balanced against a higher rate of soil water depletion due to the water to stable drainage outlets. partly to the soft vegetative approach and partly due to the more knowledge based on the relative costs of the two technologies locally. Sukkasem A. and Chinnapan W. (1996). system also increases the shear strength of soil, thereby enhances slope stability As a consequence, the vetiver-grass-based phytoremediation is a reliable . reinforcement in steep slopes. The increase was 39% Vetiver is an aromatherapy plant that is used to treat uneasiness, sleeplessness, and joint and muscular pain. Put plants into 20 litre plastic bag, and tie it closed. should not be compared with that of hydromulching either. Because of the smaller gaps between plants these strips provide protection = the Froude number of flow. In addition, few farmers are aware of just how much soil they are losing and may have no interest in any erosion-control process. The latter is native to one of the major effect of vegetation cover on sloping lands and there has been concern In addition properly laid out hedges can be designed to In this regard, VGT has done the job it was designed to do and no longer needed when the Vetiver is used to treat skin conditions that occur throughout the summer.
