The Chinese Loess Plateau has undergone extensive revegetation to restore degraded land and enhance carbon sequestration. However, soil organic (SOC) sequestrated in the profiles of deep-rooted plants not been fully studied. Here, we investigated SOC within a 0–23 m profile farmlands apple orchards converted from with different ages (A5, <5 years; A10, ~10 A15, ~15 A20, >20 years) controlling factors on three loess tablelands (Changwu, Qingyang, Luochuan). results show that stocks among showed no significant difference (p = 0.88); however, trend tree ages, i.e., decrease for A5 A10 but an increase A15 A20. For vertical variability, stock was highest 0–1 m, regardless standing age; this layer only accounted 8.8% total (97.93 ± 9.18 kg m−2). Climate 82% variations controlled changes range, while texture dominated below 1 accounting 57% variations. thick, unsaturated zones provide implications future use management sustainability arid regions.
