Effects of aggregates size and glucose addition on soil organic carbon mineralization and Q10 values under wide temperature change conditions

Abstract Soil organic carbon mineralization (SOCmin) plays an important role in soil carbon (C) cycling in terrestrial ecosystems. The contribution of soil aggregates (Sa) to SOCmin and the effects of glucose addition on temperature sensitivity of SOCmin (Q10) are not clear. A laboratory incubation experiment has been set to examine the SOCmin of Sa by changing the soil temperature and adding glucose. The undisturbed soil samples (CK) were separated into four aggregate size fractions (
