How does Vetiver Grass Root (Ramacham) Plant Amend Soil
Vetiver should be among one of the essential plants grown in your surrounding area and also in your farms.
There are a few varieties of vetiver available throughout India. The south Indian varieties are generally considered superior because it has more aromatic oil in its roots. Farmers or consumers only need its roots for consumption and other utilities. It grows upto 3 to 4 feet tall and can be cut and used as mulch or be allowed to grow further with the purpose of living mulch depending on your requirement.
Vetiver has strong, healthy and aggressively growing root system. As per modern research aromatic oil is produced in the roots with the help of certain types of bacteria which feeds on specific materials present on the roots of vetiver.
Vetiver tiller is used for Propagation from the existing harvested stock
Ramacham is one of the rare plants which go deep into the soil close to 3 meters in the soil.
It takes close to 1.5 years for the old roots to start decaying once harvested; however the same clump produces new growth with every new season. At this depth it is very difficult to till and add biomass. So the roots add biomass deep inside the soil once decayed. Another wonderful benefit of this root is that just like coconut husk or coir pit it absorbs and retains water for few days. Your farm will be like one big coir pit under the surface. This is also one of the reasons in the wild because of various tree roots water is retained in the top layer. Along with other crops ground water will also be recharged.
The aromatic oil within the roots is an effective pest deterrent. Many types of nematodes, termites will also be repelled to a great extent.
It is essential to grow vetiver as inter crop along with vegetables and fruit orchard. There has been documented improvement in the yield and health of crops. The roots will also fetch a handsome amount from the market when harvested.
