Forest Soil Carbon and Microbial Data from Subtropical Red Soils, 10-40 Year Stands

A 2026 dataset by Fuxing Tan from figshare analyzes soil organic carbon, iron oxides, and microbial communities across different forest types and stand ages in a subtropical acidic red soil region. It includes measurements of free iron oxides, iron-bound organic carbon, and microbial life-history strategies from coniferous, mixed, and broad-leaved forests aged 10, 20, and 40 years. The data supports research on soil carbon stabilization mechanisms.

Use Cases

• Modeling soil carbon sequestration potential based on forest type and stand age dynamics described in the study.
• Analyzing relationships between iron oxide content and microbial community strategies (r- vs K-strategists) as indicated in the description.
• Investigating the role of specific microbial functional traits, such as unspecific monooxygenase in broad-leaved forests, on iron-bound organic carbon formation.

Strengths

• Data spans three distinct forest types (coniferous, mixed, broad-leaved) and three stand ages (10, 20, 40 years), providing comparative structure.
• Includes multiple measured variables: soil organic carbon, free iron oxides, iron-bound organic carbon, and microbial community composition.
• Analysis includes structural equation modeling and correlation analysis with statistical significance (p < 0.05) as noted in the description.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data file is a 2.3 MB DOCX document, which may require extraction or conversion for analysis.
