2026-09-15 XDA28050303‑Black‑Soil Profile Survey Dataset doi:10.57760/sciencedb.iga.001fd en This dataset contains organic‑matter indicator data from black‑soil profile surveys, consisting of 3 Excel files (.xlsx). The dataset includes profile stratification information and soil organic carbon (SOC) content. Data contents: ‑ Profile stratification information: Upper and lower boundaries of soil horizons or depths; ‑ Organic‑matter content: SOM measurement results for each layered sample; ‑ Supplementary descriptive information: Records for anomalies, missing measurements, remarks and other items. Data Coverage: ‑ Indicator coverage: Soil organic carbon content (SOC); ‑ Structure coverage: Stratification information + indicator values + remark information; ‑ Spatial coverage: Sampling‑site scope subject to records within the files; ‑ Depth coverage: Subject to actual stratification records in each file. black‑soil profile surveys; soil organic carbon (SOC); soil horizons 潘喜才 PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
