Abstract:
... The multiple schema for the classification of soils rely on differing criteria but the major soil science systems, including the United States Department of Agriculture (USDA) and the international harmonized World Reference Base for Soil Resources soil classification systems, are primarily based on inferred pedogenesis. Largely these classifications are compiled from individual observations of so ...

Monitoring the β value, which is the slope of the linear regression relating soil δ13C to the logarithm of soil organic carbon (SOC) content, provides an approach to infer SOC dynamics. In this study, ...
