Average concentrations of K, P,
Mg, Ca in wood, bark, and branches of a Sassafras albidum. Wood concentrations are examined both for the center, middle, and outer sections of "cookies" and from the top, middle, and bottom of the tree
A cookie is a bole cross-section, roughly 2 cm thick.
The center hole is in the pith.
The middle hole is in the heartwood halfway between the
