Paddy Subsoil Carbon Response to Elevated CO2 and Temperature

A four-year field experiment investigated the impact of climate change factors on soil organic carbon in a subtropical rice paddy. Data from this study illustrates significant declines in subsoil carbon under elevated CO2 and warming conditions. The dataset was authored by Xueli Ding and published via figshare in April 2026.

Use Cases

• Analyze subsoil SOC decline under elevated CO2 and temperature treatments over four years.
• Compare the stability of topsoil SOC versus subsoil SOC using experimental condition labels.
• Model the relationship between climate variables and SOC sequestration metrics in paddy soils.

Strengths

• Data originates from a controlled four-year field experiment.
• Focuses on a specific and understudied environment: subtropical rice paddy subsoils.

Limitations

• The dataset is very small at 17.7 KB, indicating limited scope or summary-level data.
• Specific sample sizes, row counts, and measured column variables are not provided.
