USAGE

Sandalwood oil also known as fragrance oil, perfume oil, body oil and air fresners. The oil has a woody, exotic smell, subtle and lingering and the colour is pale yellow to pale gold. The essential oil contains Alpha-santalol and beta-santalol amount to more than 90 % of the oil – making it very superior sandalwood oil. The main chemical components are santalol, santyl acetate and santalene (Bo Jensen, Denmark). Sandalwood oil is used in many therapies to control muscle problem, mental disorders, fighting bacteria and many more.

Soil

Red ferruginous loam is the most common soil on which sandal tree occurs, the underlying rock often is metamorphic and chiefly gneiss. It is not exacting as to the depth of the soil and is frequently found on rocky ground and on stony or gravelly soils.

Sandal requires good drainage and does not stand water logged ground. Best growth of tree is on rich fairly moist such as garden loam and well drained deep alluvium on the river banks. (Troup, 1921) Sandal grows better in slight alkaline condition soil PH Range between 6.7. To 7.5.

Climate

Sandalwood grows best between attitudes of 700 to 1100m though it may go up to 1500m and descend as low as 300m.

Silviculture

Silviculture guidelines to minimize fungal attack risk to the Tropical sandalwood industry. The recommendations will as follows:

1. High risk periods of high spore count in the air and what weather events cause a greater presence of spores.
2. High risk periods of high spore count in the water system and what irrigation events cause a greater presence of spores. Methods of branch pruning – branch size, optimum length of stump, sealing of pruning, chemical spraying after pruning the plantation.
3. A pruning strategy of single verses multiple stems on heartwood production. On the one hand, multiple stems may produce less heartwood oil than a single stem; however, the reduced pruning may reduce fungal attack.
4. The effect of root pruning on fungal presence in sandalwood trees.
5. The risk of keeping infected trees within a plantation.

Heart Wood Formation & Oil Content

Heartwood formation in sandal trees generally starts around 10-13 years of age, but what trig-gers this process has not been very well understood. Certain factors, generally relating to stress, such as gravelly dry soil, insolation, and range of elevation (500-700 m), seem to provide the right environment for the formation of heartwood, irrespective of the size of the stem after 10 years of age. The occurrence of heartwood varies. The value of heartwood is due to its oil content, and the superiority of the oil is due to the percentage of santalol.

1. In a tree the oil content is highest in the root, next highest in the stem at ground level, and gradually tapers off towards the tip of the stem.
2. Similarly, there is a gradient in oil content from the core to the periphery of the heartwood in a stem.
   
   Depending upon their age, trees can be called young or mature, although this is an empirical classification and holds good only for a particular population. The oil content and its composi-tion may differ at the same age:
3. Young trees (height less than 10 m, girth less than 50 cm, and heartwood diameter 0.5-2 cm) have heartwood with 0.2-2 percent oil content, which has 85 percent santalol, 5 percent ace-tate, and 5 percent santalenes.
4. Mature trees (height 15-20 m, girth 0.5-1 m, and heartwood diameter 10-20 cm) have heartwood with oil content of 2- 6.2 percent, which has over 90 percent santalol, 3-5 percent acetate, and 3 percent santalenes.

Pest And Disease:

Spike disease is one of the important diseases of sandal. This disease is caused by mycoplasma-like organisms (MLO). It can occur at any stage of development of the tree. As the disease progresses, the new leaves become smaller, narrower or more pointed and fewer in number with each successive year until the new shoots give an appearance of fine spike. At the advance stage of disease, the inter nodal distance on twigs becomes small, haustorial connection between the host and sandal breaks and the plant dies in about 2 to 3 years.

Spread of disease is sporadic and the disease is transmitted in nature by insect vectors. It has been found that other insect vectors in addition to Nephotettix virescens may also be responsi-ble for transmission of disease. So far no permanent remedial measures have been prescribed for control of spike disease.

Stem borers Zeuzera coffease Nietn (red borer) Indarbela quardinotata Walker (bark-feeding caterpillar) and Aristobia octofasiculata Aurivillius (heartwood borer) are some of the pests causing considerable damage to living trees.

Harvesting, Yield & Returns

The price of Sandalwood in India is everyday increasing price Rs. 20,000 per tonne in 1980, Rs. 200,000 per tonne in 1990; Rs. 4000,000 per tonne in 2004 and 7500,000 per tonne in 2014. India uses all S. album domestically and export is prohibited (USDA, 1990). Export of timber from India is totally banned except for handicraft pieces of sandalwood up to 50g weight. FAO, 1984 notes that it is a priority species for in setup conservation. Since then, sandalwood oil and handicrafts have become more important. International demand for sandalwood is estimated to the 10,000 mt per year. USA and France are the two largest importers of Indian sandalwood oil. Imports into the Middle are also increasing.
