Abstract:
... Biomass sorghums [Sorghum bicolor (L.) Moench] are short-day photoperiod sensitive (PS) types, meaning that the crop will grow vegetatively late into the fall season in subtropical and temperate environments. This feature results in high biomass yield potential and mitigates drought susceptibility. The objective of this study is to assess biomass growth patterns and associated changes in compositi ...

Abstract:
... Previous greenhouse gas (GHG) assessments for the shrub willow biomass crops (SWBC) production system lacked quantitative data on the soil CO₂ efflux (Fc). This study quantifies the mean annual cumulative Fc, the C sequestration in the above- and belowground biomass, and the carbon balance of the production system. We utilized four SWBC fields, which have been in production for 5, 12, 14, and 19 y ...
