How do changes in bulk soil organic carbon content affect carbon concentrations in individual soil particle fractions? X. M. Yang, C. F. Drury, W. D. Reynolds & J. Y. Yang We test the common assumption that organic carbon (OC) storage occurs on sand-sized soil particles only after the OC storage capacity on silt- and clay-sized particles is saturated. Soil samples from a Brookston clay loam in Southwestern Ontario were analysed for the OC concentrations in bulk soil, and on the clay (
