Readily oxidizable carbon
WebThe mass fractions of total organic carbon, recalcitrant organic carbon, readily oxidizable organic carbon,microbial biomass carbon and dissolved organic carbon in each soil layer at 0–10, 10–20, 20–40 and 40–60 cm were measured, and the change characteristics of soil organic carbon components were also studied and compared.
