Peri-Rhizosphere Soil Carbon Data from Eight Cropland Sites

A paired dataset from eight cropland sites compares soil organic carbon (SOC), dissolved organic carbon (DOC), particulate organic carbon, and enzyme activity between classical rhizosphere, peri-rhizosphere, and bulk soil fractions. The dataset includes China-scale extrapolation under current and future climate scenarios. It was authored by Jian-Ying Qi and last updated on April 10, 2026.

Use Cases

• Modeling the spatial extent of root-associated carbon accumulation based on SOC and DOC enrichment data.
• Comparing carbon pool dynamics between particulate and mineral-associated organic fractions.
• Analyzing the coupling between SOC variation and DOC or particulate organic carbon using delta-based analyses.
• Projecting soil carbon retention under future climate scenarios using China-scale extrapolation data.

Strengths

• Data from eight distinct cropland sites provides comparative analysis.
• Includes multiple carbon metrics: SOC, DOC, particulate organic carbon, and mineral-associated organic carbon.
• Paired field design allows direct comparison of classical rhizosphere, peri-rhizosphere, and bulk soil.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Geographic coverage is limited to eight sites, though extrapolation is performed.
