Note: We are currently experiencing issues with the REST API for SoilGrids, and have decided to temporarily pause the service. We are working on a solution. However, at this time, we cannot provide an estimated timeline for when the service will be restored.

Please note that our API is a complementary service we provide to access SoilGrids. It is still under active development (beta stage). Occasional issues and downtimes may occur. We want to emphasise that it does not come with a guarantee of uptime or other types of support. Please remain informed about its status, especially if you are planning to build a production system based on it.

There are alternative, more stable ways to access SoilGrids that, in this case, may better suit your needs. More information on alternative ways to access SoilGrids can be found here. We will update as soon as the service is restored.

SoilGrids is one of ISRIC’s flagship products. It is a system for global digital soil mapping that uses state-of-the-art machine learning methods to map the spatial distribution of soil properties across the globe. SoilGrids prediction models use soil profile observations from the WoSIS database along with a series of environmental covariates. Covariates are selected from 400 environmental layers and other environmental information such as climate, land cover and terrain morphology.

SoilGrids's provides global maps of fourteen soil properties at a spatial resolution of 250 meters, for six standard depth intervals. The uncertainty of the predictions is quantified for each pixel. The properties available are pH, soil organic carbon content, bulk density, coarse fragments content, sand content, silt content, clay content, cation exchange capacity (CEC), total nitrogen as well as soil organic carbon density and soil organic carbon stock. SoilGrids follows closely the specifications established by the GlobalSoilMap Working Group of the International Union of Soil Sciences.

The SoilGrids maps are publicly available on the SoilGrids website under the CC-BY 4.0 License.

SoilGrids was funded from ISRIC's core funding, with additional support from the EU-H2020 CIRCASA project.

A wide range of agencies and experts have provided data for the WoSIS/SoilGrids effort; we gratefully thank them for their contributions.
