Free-Air Carbon Dioxide Enrichment of Soybean--Influence of Crop Variety on Residue Decomposition

Elevated atmospheric C(O)2 can result in larger plants returning greater amounts of residue to the soil. However, the effects of elevated C(O)2 on carbon (C) and nitrogen (N) cycling for different soybean varieties have not been examined. Aboveground residue of eight soybean [Glycine max (L.) Merr.]...
