Plain language summary
The soil carbon (C) accumulation rate was determined for switchgrass, as compared with selected C3 species in Nova Scotia, Canada. There was no effect of crops on total soil C retention, while soil 13C signature (δ13C) was enriched by 0.4‰ in switchgrass relative to other C3 species and C accumulation rate was 0.1 Mg-1ha-1yr-1 in the top 30-cm depth.
Abstract
The soil carbon (C) accumulation rate was determined for switchgrass, as compared with selected C3 species in Nova Scotia, Canada. There was no significant effect of crops on total soil C retention, whereas soil13 C signature (δ13 C) was enriched by 0.4‰ in switchgrass relative to other C3 species, and C accumulation rate was 0.06 Mg ha−1 yr−1 in the top 30 cm of soil.
