Brown bast/TPD in detail

Formation of rubber roots by sleri
The picture shows the formation of new roots by slery where grasses was not available due to soil degradation. The highest place behind a tree needs organic matter to grow the roots. The soluble organic matter will flow to the lower place where earth worms can maitain the soil more fertile.
Biogas slery for Rubber trees
This BIOGAS plant completed by Biotec. This plant is able to maintain drainage waste with a safety precaution as water jacket system. Cow dung, waste water of rubber sheets and drainage waste without bathroom water can be used in it. Sufficient NPK are avilable in the slery for the growth of rubber trees. But the DRC will increase due to the availability of organic matter. In organic peat soil deficiency of magnesium will create Brown bast. Thus the application of magnesium is necessary to avoid Brown bast.
Main parts and functions of stem

The rubber tree expands with secondary growth, new phloem forms on one side of the cambium tissue, and new xylem on the other. This secondary xylem is known as rubber wood. Phloem is the path of carbohydrates from leaves to root end through the inner part like Artery in the human body. Between the cork cambium and phloem latex vessels are available with a flow from root to leaves like Vain in the human body. The deficiency of carbohydrates will dry the phloem at tapping period and cork cambium will more thicker in first stage without latex vessels.

Will be corrected and completed as soon as possible.
