Description
A global soil data set containing 131,472 samples from 20,920 profiles, prepared by ISRIC for the IGBP-DIS Global Soil Data Task. The data were derived from ISRIC's Soil Information System and USDA-NRCS sources, clustered by textural class and clay mineral activity. It is intended for developing pedotransfer functions for key soil properties like organic carbon, total nitrogen, and water holding capacity.
Use Cases
Developing pedotransfer functions for soil organic carbon based on soil sample clusters.
Predicting soil water holding capacity using derived chemical and physical soil data.
Modeling soil thermal properties for climate and ecosystem studies.
Analyzing global soil total nitrogen content from clustered sample data.
Strengths
Contains data for 131,472 soil samples from 20,920 profiles.
Samples are clustered into 9 functional groups based on textural class and clay mineral activity.
Derived from authoritative sources including ISRIC's ISIS and USDA-NRCS data.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Last update date is unknown; freshness unverified.
Row count is unknown, which may limit suitability assessment.
