- 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 soil ¹³C signature (δ¹³C) 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.
