Carbon debt of field-scale conservation reserve program grasslands converted to annual and perennial bioenergy crops
Over 5 million ha of US Conservation Reserve Program (CRP) grasslands have been converted to annual crops since 2000, driven mainly by demand for corn grain ethanol. Much of the soil carbon sequestered under CRP is lost upon conversion, creating a ‘carbon debt’ that is presumed to be repaid by futur...
