Building on earlier research showing the carbon payback time of biofuel crops grown on certain types of land, the new study uses «a new, geographically detailed database of crop locations and yields, along with updated vegetation and soil biomass estimates, to provide carbon payback estimates that are more regionally
specific than those in previous studies,» write the authors.
The new protocols of sequencing and analysis allow us to extract quite more information
than in previous studies, which were limited to
specific regions or surface waters, to an unprecedented level of resolution.»
