Dear Author I am working attached to the Rubber Research Institute of Sri Lanka and did so many experimental works related to soil fertility mgt for rubber growing soils. Actually, I did much experiment related to the studies of the microbial application. Therefore, I prefer to follow much current research related to that field, and this book gives much more support for those activities Further soil P application is very much important to us and hopes to apply activities included in the text for enhancing fertilizer use efficiency under rubber plantations.
