The logs of plantation forest are much smaller in size and having a considerably higher percentage of sapwood when compared to the logs of natural forest. The research and development of plantation timbers emphasizes on the analyses of the logs in order to assess the expected output of sawmills, to give initial indication of the drying and machining processes, plus to provide insight regarding the potential usage. This article explains on the analysis and formulae concerning the proportion of the sapwood/heartwood of plantation logs.
