Soil Responses to Bioenergy Crop Production in the North Carolina Piedmont
AGRONOMY JOURNAL, 109(4), 1368–1378.
Core Ideas Three bioenergy and two traditional cropping systems were compared in the North Carolina Piedmont. Bioenergy crops sorghum, switchgrass, and giant mischanthus produced large yields. Removal of N, P, and K was least for perennial bioenergy crops. Perennial bioenergy crops had slightly poorer soil physical conditions after 3 yr. Organic C pools were greatest with giant miscanthus and fescue.
