Describes a series of periodic analyses on one-year-old Populus 'I-214' nursery stock to determine, on the basis of (1) the dry-matter production of each tree as a whole (roots excluded) and (2) the relative content of N, P2O5 and K2O, and of its component parts (leaves, bark, wood) the quantities of nutrients taken up by the roots between each date of measurement (roughly one month apart), and their net accumulation in the various parts of the tree, throughout the annual cycle of growth.
