Current and Potential Soil Carbon Storage in Chilean Patagonia Volcanic Soils

1,660 soil samples from a national database covering the Chilean latitudinal gradient were used to model soil organic carbon (SOC) storage thresholds. The dataset includes 173 samples from the Aysén Region, showing an average SOC storage potential of 358 t C ha⁻¹, with current stocks 33.5% below capacity. Authored by Michell Figueroa and last updated in April 2026, this dataset quantifies carbon sequestration potential in volcanic soils.

Use Cases

• Modeling soil organic carbon storage potential based on reactive aluminum (Alₐ) content mentioned in the description
• Comparing current versus potential carbon stocks across different land uses (e.g., agricultural crops, grasslands, wetlands)
• Informing land management strategies aimed at enhancing carbon storage in volcanic soils
• Assessing the adequacy of soil texture-based models for estimating SOC in mineral-reactive soils

Strengths

• Based on a national soil database of 1,660 samples, providing a broad latitudinal gradient
• Includes 173 specific samples from the Aysén Region with detailed land-use context
• Quantifies a specific average SOC storage potential of 358 t C ha⁻¹ and a 33.5% capacity gap
• Released under a permissive CC-BY-4.0 license for reuse

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count for the primary dataset is unknown, which may limit suitability assessment
• The 101.7 KB file size suggests a limited scope, likely containing summary or model results rather than raw measurements
