Nutrient Exportations in Very-Short Rotation Coppice of Poplar

A. Berthelot, P. Maine, M. Preudhomme, J. Gauvin & J. Ranger
The production of above-ground biomass (leaves aside) was studied for six very-short rotation coppice stands (VSRC) of 1 or 2 year-old poplars planted on various sites. The number of stumps by hectare ranged from 5600 to 13330, the number of stems by stump from 1 (first rotation) to 16 (depending on rotations) and the -1 -1 production of biomass from 0,9 to 10 dt.ha.y . Wood chips coming from the harvested biomass were analysed to...
