83 georeferenced soil profiles with 282 genetic horizons from Réunion Island provide a harmonized dataset of morphological and physicochemical properties. Frédéric Feder from CIRAD compiled field descriptions following FAO/WRB guidelines and analytical results including organic carbon, pH, cation exchange capacity, and selective Fe-Al-Si extractions. The dataset covers a wide pedogenic gradient with higher sampling density in a reference area.
Use Cases
- Classify soils according to the World Reference Base (WRB) based on diagnostic horizons and analytical properties.
- Model phosphate retention and nutrient availability based on selective extractions of iron, aluminum, and silicon.
- Analyze short-distance soil transitions and variability within a tropical volcanic landscape.
- Correlate physicochemical properties like bulk density and particle size distribution with field morphological descriptions.
Strengths
- 83 soil profiles provide a substantial sample size for a regional study.
- 282 genetic horizons offer detailed vertical stratification data.
- Data harmonization combines field descriptions, routine chemical properties, targeted indicators, and physical properties.
- Profiles are georeferenced, enabling spatial analysis.
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 2026-05-09.
