Poplar Biomass at Harvest
Poplar plots are clearcut and biomass is measured, by weighing the biomass harvested. Biomass is the standing crop, or production since last clearcut, in g/m2, based on 9088 m2. However, poplar density is not constant across the plots. The 2007 data are from the S1x2m planting density on the southern half of the plot.
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.
