Soil Properties of Brazilian Forested Headwater Catchments

185 georeferenced soil samples from a 20x20 meter grid across four headwater catchments in Juruena, Mato Grosso, Brazil. The dataset maps soil classes to the second category level of the Brazilian System of Soil Classification, analyzing texture and color variability at two depths. It was produced by ORNL_CLOUD, with platform metadata showing conflicting last update dates of 2004 and 2026.

Use Cases

• Mapping soil class distribution (e.g., Plintossolos, Argissolos, Latossolos) using geostatistics and the Brazilian Soil Classification System.
• Analyzing the relationship between soil color (redness index of diagnostic horizons) and soil classification categories.
• Studying the correlation between topographic position, elevation (below/above 280m), and soil type in forested headwater catchments.
• Validating geostatistical models for soil property prediction using field-sampled texture and color data from 0-20 cm and 40-60 cm depths.

Strengths

• Contains 185 precisely georeferenced sample points from a systematic 20x20 meter grid.
• Soil classes are mapped to the 2nd category level of the official Brazilian System of Soil Classification.
• Sampling at two depths (0-20 cm and 40-60 cm) allows for vertical profile analysis.
• Field validation and pedologic knowledge were incorporated into the mapping process.

Limitations

• Conflicting last updated dates exist between sources: one states 2004-08-18, another 2026-03-13.
• Specific column names, row counts, and dataset size are not provided by any source.
• The license is ambiguously listed as 'other-license-specified' without further details.
