Carbon isotope ratios of great plains soils and in wheat-fallow systems

The purposes of this study were to improve knowledge of regional vegetation patterns of C3 and C4 plants in the North American Great Plains and to use delta 13C methodology and long-term research sites to determine contributions of small-grain crops to total soil organic carbon (SOC) now present.
