2026-08-28 Dataset of soil aggregates and aggregate‑associated organic carbon in Robinia pseudoacacia mixed‑plantations, Loess Plateau, China doi:10.57760/sciencedb.010kp en This dataset supports the manuscript "Companion species and soil depth drive asynchronous responses of aggregate stability and aggregate‑associated carbon in mixed plantations".Soil samples were collected from six plantation stands in Wuqi County, Loess Plateau: Robinia pseudoacacia monoculture (RP), five mixed‑plantation types (RP×AS, RP×HR, RP×AF, RP×PD, RP×PT). Soil layers: 0‑10 cm, 10‑20 cm, 20‑40 cm.Measurements include site stand characteristics, soil physicochemical properties, water‑stable aggregate size distribution, MWD, aggregate‑associated organic carbon (ASOC), particulate‑associated organic carbon (APOC), mineral‑associated organic carbon (AMOC), and root morphological traits.
