In the plantation industry, it is essential to carefully assess the ecological conditions at the planting site and to assess whether a potential species will survive and grow. Agarwood Plant is not demanding regarding soil and climatic conditions, occurring naturally in all ecological zones and on a variety of soils (avoid clay soil). Planting on sloping lands is therefore recommended.
To reduce the mortality rate, seedlings are ready to transplanting into ground when achieving 60~90cm height. Older seedlings might not be good due to root coiling in the confined polybag if polybag is not big enough. Don’t buy seedlings with small polybag older seedling 120cm and above. There are various ways to plant Agarwood (Gaharu) seedlings.
From Seedling to Mature for 6 Year
At the end of the 6th year the tree has to be stressed to produce the resin. Thus the inoculation procedure has to be done. The trunk will be harvested every four months once until the whole tree is felled. After the INNOCULATION has been completed there is a waiting period of 18 months where the tree will be cut down and the wood pieces will be crushed into wood dust.
The Bark of the tree is carefully removed to apply the inoculation solution
Every tree is then Labelled to identify the cut down after 18 months
OIL EXTRACTION PROCESS
The most important aspect when extracting the essential oil is to ensure that the fungus inoculated in the tree that are at least 6 – 8 years old in order to obtain the oil. The extraction process is carried out through water or steam distillation. At the first stage of steam distillation process, the Agarwood is immersed in water for one-three months. Then, the soaked wood dust is placed in huge boilers where the water evaporates along with the resin and collected in a condenser. The steam extraction method is more popular in the East – Asian countries. Water distillation is the process for obtaining essential oils. In this method, Agarwood dust are fully submerged in water, producing a wood ‘soup’, followed by boiling process in huge boilers. The steam containing the aromatic plant molecules is captured and condensed, and the oil floats to the top of the distilled water component. When the condensed material cools down, the oil and hydrosol are separated and the essential oil
