Short summary
Switchgrass is a deep-rooted perennial grass bioenergy crop that can sequester soil C. Although switchgrass ecotypes vary in root biomass and architecture, little is known about their effect on soil microbial communities throughout the soil profile. By examining labeled root-C uptake in the microbial community, we found that ecotypes supported different microbial communities. The more fungal community associated with the upland ecotype could promote C sequestration by enhancing soil aggregation.
