Short summary
Dedicated bioenergy crops are required for future energy production; however the effects of land use change from traditional crops to biofuel crops on soil microbial communities, which drive greenhouse gas production, are largely unknown. We used quantitative PCR to enumerate these microbial communities to assess the sustainability of different bioenergy crops, including miscanthus and corn. We found that miscanthus may be a suitable crop for bioenergy production in variable Ontario conditions.
