Chemical composition varies with tree part (root, stem, or branch), type of wood (i. e., normal, tension, or compression) geographic location, climate, and soil conditions. Analytical data accumulated from many years of work and from many different laboratories have helped to define average expected values for the chemical composition of wood.
