RADAMBRASIL: Soil Profile Data for the Amazon Basin

1,153 soil pits across the Amazon basin were described and sampled by horizon for texture and chemical composition. The data provides detailed soil profile descriptions based on the extensive RADAMBRASIL project surveys. It is stored in an ASCII comma separated format and includes companion documentation.

Use Cases

• Analyzing soil texture and chemical composition variations across the Amazon basin.
• Classifying soil types and horizons based on detailed profile descriptions.
• Modeling soil carbon and nitrogen stocks using horizon-specific data.
• Validating regional soil maps derived from aerial photography and geologic maps.

Strengths

• Contains data from 1,153 physically described and sampled soil pits.
• Profiles are analyzed by horizon for texture and chemistry, providing vertical detail.
• Based on the extensive, basin-wide RADAMBRASIL mapping project.

Limitations

• Column names and exact data structure are not specified in the provided metadata.
• Conflicting last-updated dates exist between platforms (1986 vs. 2026), suggesting potential metadata issues.
• The specific license terms under 'other-license-specified' are not detailed.
