The study on vetiver grass has been done for about 17 years now. Although it has been a long time, the grass has created a number of benefits which are highly effective. It is such a miracle that this kind of grass can produce benefits for different area conditions may it be the plains or the mountains, shallow soil or deep soil. For the deep soil, it appears that the root of this grass can go down up to 5 to 6 metres and does not spread to the sides which means that it is not dangerous to the root system of the plants that are useful.
