During the 4‐yr period of this trial, N fertilization increased dry matter yield in 2 out of 4 yr for biomass sorghum and there was no effect on dry matter yield of sweet sorghum.
High DM yield supports sorghum as a bioenergy crop, however, the relatively low nutrient removal rate may limit its utilization in nutrient‐rich environments such as spray fields.
Greatest dry matter yields achieved were ∼18.5 Mg ha−1 at a N fertilization rate of 67 kg N ha−1 yr−1 for biomass sorghum.

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.
