Younger trees are likely to contain up to 80 % of the total inorganic constitution of sof-twoods and hardwoods. Among them Ca predominates constituting often up to about 50 % of the total inorga-nics. A variety of other elements can also be detected in wood tissues, altogether about seventy, however only ed so far as essential, meaning that life cycle. These are the above mentioned carbon (C), nickel (Ni) and chlorine (Cl). N, P,
