Soil pH classes for the world (0-20cm) with relative proportion of dominant class

Which soils are suitable for rice production? Where do degraded soils occur and why did they degrade? What is the water holding capacity of these soils? When studying global issues such as food security or climate change mitigation, researchers and other interested parties often need detailed soil information. ISRIC – World Soil Information, in collaboration with its partners, is developing a wide range of datasets and webservices that are crucial for solving the five big problems of our time: food insecurity, climate change, environmental degradation, water scarcity, and threats to biodiversity; this is "a new era for soil science" writes Rik van den Bosch, Director ISRIC


Data download facility

In collaboration, ISRIC has been working for over 40 years on datasets and maps at local, national and global scale and at various resolutions. Our website provides access to a data download facility, through which ISRIC project-related data sets can be downloaded. A wider range of information (datasets, reports, scanned maps) can be queried and accessed using ISRIC's GeoNetwork metadata service; this service harvests soil-related metadata from a wide range of data providers.


World Soil Information Service

ISRIC is developing a centralized and user-focused database known as WoSIS (World Soil Information Service). This service will Here users will be able to easily extract "shared", validated and authorized data from the ISRIC data repository (see Data Policy) - soil profile data as well as area-class soil maps. Through a single set of web tools, WoSIS will allow visitors to access, process and visualize various types of soil-related data. 


SoilGrids is a collection of updatable soil property and class maps of the world, initially at a resolution of 1 km, produced using state-of-the-art model-based statistical methods;  the SoilGrids system is intended to facilitate global soil data initiatives and may serve as a bridge between global and local soil mapping, particularly in countires with limited soil survey data. 

SoilGrids is part of GSIF, the Global Soil Information Facility, aimed at facilitating global digital soil mapping. To save and help collate new soil data, ISRIC is constructing a framework for soil data storage called SoilInfoApp, that is linked to WOSIS. The SoilInfoApp concept is based on crowd sourcing and resembles the Wikipedia approach. Individuals and organizations collecting soil data or working with existing soil information are invited to contribute their data to the WoSIS effort. Intellectual property and other rights remain with the data provider(s), and  ‘access rights’ are fully documented in the metadata and data access register (see Data Policy).
