Poplar Yield — 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Yield (areal biomass) of poplars (T5) as determined by clearcutting and weighing of harvested biomass. Biomass is recorded as the woody production since planting or coppicing and is based on complete harvest of the main plot area (i.e., entire plot minus microplot area).

This datatable is part of the Primary Production of the Poplar Treatment of the Main Cropping System Experiment dataset.

This dataset contains allometric and areal biomass data for the Poplar treatment (T5) of the Main Cropping System Experiment (MCSE) at the LTER Main Site. The Poplar treatment is managed as a short-rotation woody biomass system on an approximate 10-year rotation cycle with replanting or coppicing after harvest. Rotations are as follows:

  • First: planted in April 1989 with stem cuttings of Populus nigra x P. deltoids hybrid at a stocking density of 1 tree per 2 square meter, harvested in February 1999.
  • Second: trees allowed to coppice after 1999 harvest, coppicing produced multiple stems per tree, coppiced regrowth harvested in January 2008.
  • Third: planted in May 2009, after a fallow year, with stem cuttings of Populus nigra x P. maximowiczii at a density of 1 tree per 3.6 square meter, harvested in February 2018.
  • Fourth: planted in June 2019, after a fallow year, with stem cuttings of Populus nigra x P. maximowiczii at a density of 1 tree per 3.6 square meter.
