Global Stabilized Soil Organic Carbon Stocks and Drivers

A global assessment of stabilized soil organic carbon (SSOC) stocks and controlling factors in the surface one-meter layer. The dataset estimates a global SSOC stock of 1300 Pg C, with wetlands storing the largest pools per hectare. It was created by Zhaoxin Li and last updated in May 2026.

Use Cases

• Modeling soil carbon sequestration potential based on SSOC stock estimates.
• Analyzing the influence of soil properties (SOC, pH, bulk density) on carbon stabilization.
• Mapping global SSOC distribution across land types (wetlands, forests, grasslands, croplands).
• Evaluating soil negative carbon potential (SNCP) as an indicator for climate mitigation strategies.
• Benchmarking Earth system models with global SSOC stock data.

Strengths

• Provides a global estimate of 1300 Pg C for stabilized soil organic carbon stocks.
• Identifies soil properties as the dominant moderating factor (77-92%) for SSOC.
• Includes geospatial data formats (TIF) and tabular data (CSV, RData) totaling 102.9 MB.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the last update date is May 2026.
