Coppice Poplar Branch and Stem Biomass — Main Cropping System Experiment (MCSE)
Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Poplars were clearcut in 1999. Since then, several trees per plot per year have been destructively sampled. This table integrates stem and branch data (KBS019-011 and KBS019-012).
This datatable is part of the Poplar Biomass by Allometric Equations dataset. Poplars are grown as cellulose crop at the Main Cropping System Experiment. The first rotation was planted at a stocking density of 1 tree per 2 square meter. After the first harvest the trees were allowed to coppice. After the second harvest the trees were replanted. The third rotation was planted at 1 tree per 3.6 square meter. For the first two rotations the species planted was Populus nigra x P. deltoids hybrid for the third rotation it is Populus nigra x P. maximowiczii.
