is a Data Source.
It is part of the BER collection.
The Soil Survey Geographic Database (SSURGO) is a detailed digital soil-survey dataset produced by the USDA Natural Resources Conservation Service (NRCS). It provides spatial map units and associated tabular attributes describing the physical and chemical properties of soils across the United States, generally at scales from 1:12,000 to 1:63,360. SSURGO is the most detailed level of the USDA soil-survey series and is widely used in land management, agriculture, and environmental modeling. It serves as an upstream data source for KnowWhereGraph.

The Soil Survey Geographic Database (SSURGO) is the most detailed level of soil mapping produced by the USDA Natural Resources Conservation Service (NRCS). It captures soil-survey map units as spatial polygons together with extensive tabular attributes describing soil composition, physical and chemical properties, and interpretations for use.
SSURGO data are collected and distributed by survey area (typically a county or similar unit) and are commonly applied in agriculture, land-use planning, and environmental modeling. The database is an upstream data source for KnowWhereGraph.
