ISRIC Soil Information System (ISIS)

ISRIC Soil Information System (ISIS) brings the ISRIC Soil Reference Collection on-line and characterizes a collection of monoliths with morphological, analytical data that represent the main soil reference groups of the World Reference Base for Soil Resources (WRB). ISIS holds data on the World Soil Reference Collection including over 950 monoliths from over 70 countries with detailed soil profile and environmental data. Users currently have access to site data (60 attributes on location, geology, landform, soil surface properties, hydrology, land-use, vegetation and climate) and soil data (soil profile description according to the FAO Guidelines; 100 physical, chemical and mineralogical attributes; and attributes for classification in the FAO-Unesco Legend (1974), the Revised FAO-Unesco Legend (1988), World Reference Base for Soil Resources (2006), USDA Soil Taxonomy, and a national classification system, as available). ISRIC will continue to enlarge its soil reference.
