Hello azirgraff, more and more demand in the world timber industry. while the availability of high-quality seeds is very low. I think this technique is very effective hopefully this becomes a medium of socialization and information about teak planting, in the hope that farmers no longer plant teak from seeds that are not qualified. and also the pattern and method of planting in the cultivation of teak better by to make hedge orchard as a source of teak for producing high-quality seeds
