Revealing the changes in organic carbon (OC) and labile (LOC) fractions soil aggregates is of great significance for better understanding sources sink effects tea plantations. In this study, samples were collected at 0–20 cm depth plantations with different stand ages (including 0 years (nudation), 8 years, 15 23 years) Guangxi, China. Then, divided into sized >2 mm, 2–1 1–0.25 <0.25 mm) by a suitable moisture classification method determination OC LOC fractions. aggregate stability (as indicated mean weight diameter (MWD) geometric (GMD)) was highest cultivation, indicating that these (15-year-old) had stable structure provided physical protection storage. At depth, stocks mainly distributed mm aggregates, regardless ages, implying main carriers During first increased then decreased, reaching levels which critical point from to source after cultivation. Therefore, attention should be paid late (15–23 stage so as maintain effect
