USDA soil taxonomy

USDA Soil Taxonomy developed by United States Department of Agriculture and the National Cooperative Soil Survey provides an elaborate classification of soil types according to several parameters (most commonly their properties) and in several levels: "Order", "Suborder", "Great Group", "Subgroup", "Family", and "Series".

Example of classification of a soil type

Order: Entisols :Suborder: Fluvents ::Great Group: Torrifluvents:::Subgroup: Typic Torrifluvents ::::Family: Fine-loamy, mixed, superactive, calcareous, Typic Torrifluvents:::::Series: Jocity, Youngston.

Another Example

Order: Alfisols:Suborder: Xeralfs::Great Group: Durixeralfs:::Subgroup: Abruptic Durixeralfs::::Family: Fine, Mixed, Active, thermic Abruptic Durixeralfs:::::Series: San Joaquin (soil)Link to Official Series Description:
