Selection of Optimum Rotation Time for Maximum Biomass Production of Fast-Growing Tree Species

H. Shin, J.-K. Yeo & Y.-B. Koo
For maximum biomass production of fast­growing tree species used as raw material of pellet or bioethanol, it is important to select optimal rotation time. We planted twelve clones of Populus and Salix spp. In fallow land with three different ration times and compared biomass production. Harvested biomass varied with clones as well as rotation time. Survival rates were decreased in all clones by years and the annual rotation clones showed drastic mortality after the first­year...
