Quantifying C stocks in high-yield, short-rotation woody crop production systems for forest and bioenergy values and CO2 emission reduction
Short-rotation woody crop (SRWC) systems sequester atmospheric CO2 in their fibre and surrounding soil. Studies have promoted the carbon (C) sequestration potential of concentrated SRWC systems, but most examine only aboveground biomass and soil organic carbon (SOC) stocks on young systems (<6 ye...

| description | Short-rotation woody crop (SRWC) systems sequester atmospheric CO2 in their fibre and surrounding soil. Studies have promoted the carbon (C) sequestration potential of concentrated SRWC systems, but most examine only aboveground biomass and soil organic carbon (SOC) stocks on young systems (<6 years). The objectives of this study therefore were, (a) to quantify above- and belowground carbon stocks within an 8-year-old concentrated SRWC system and (b) to compare SOC stocks between SRWC systems and an adjacent conventional agricultural system. Fibre C accumulations among clones in concentrated SRWC systems ranged from 1.02 to 5.34 t ha-1 y-1. SOC stocks for concentrated SRWC averaged 78.66 t C ha-1 (0-30 cm), with an increase of 1.16 t C ha-1 y-1 compared to the baseline measurements in 2009 (69.42 t C ha-1). SOC stocks for the agricultural system (0-30 cm) have dropped to 63.80 t C ha-1, averaging a loss of 0.70 t C ha-1 y-1 since 2009. Results presented in this study suggest that concentrated SRWC systems have the potential to mitigate climate change through the sequestration of significant amounts of atmospheric CO2 in their biomass and in soils. |
