ISRIC provides quality-assessed soil data and information to the global community. We collate, assess and standardise existing data sets describing basic soil chemical and physical properties for geo-located soil profiles. Using these point datasets, we develop new global and continental datasets through digital soil mapping.
ISRIC has two flagship soil information products: World Soil Information Service (WoSIS) and SoilGrids.
Launched in 2013, WoSIS is a unique, centralised global soil database that safeguards, standardises, and serves soil profile data. WoSIS draws on voluntary contributions from numerous data holders/providers worldwide who are willing to share their data for the greater benefit of the international community. By mid-2025, it comprises about 230,000 geo‑referenced profiles from 174 countries, representing over 900,000 soil layers and more than 6 million soil records (see Batjes et al, 2024). All the data is harmonised using compliant methods and accessible here.
SoilGrids is a system for global digital soil mapping that makes use of global soil profile information and covariate data to model the spatial distribution of soil properties across the globe. SoilGrids is a collection of soil property maps for the world produced using machine learning. It provides global maps of soil properties (among others pH, organic carbon, bulk density, texture fractions, and water content) at a spatial resolution of 250 meters, for six standard depth intervals. SoilGrids uses the soil profiles from WoSIS, along with numerous environmental covariates layers, including climate, land cover, and terrain data. It also quantifies prediction uncertainty, and it follows the GlobalSoilMap specifications. The SoilGrids maps are publicly available here.
