Agalawatta, 1998) Samarappuli, L.; Yogaratnam, N.Cultivations of deep rooting perennial crop like rubber is considered as a very desirable from of land use. They not only provide a canopy which reduces the adverse effects of excessive atmospheric warming but also many beneficial effects such as non removal of significant amount of soil water per unit area of land. Rubber plantations simulate to a natural forest condition but with an economical benefit.
