USDA soil survey context for land, development, agricultural, and due-diligence workflows.

US Soils is published by USDA NRCS Soil Data Access and covers United States soil survey areas represented in SSURGO or STATSGO.

It refreshes on a schedule the publisher sets.

Last verified . That is when these facts were last rebuilt from the ParcelOps source registry, not when USDA NRCS Soil Data Access last refreshed the data itself.

API access

What this source cannot tell you

  • ⚠ Anything outside United States soil survey areas represented in SSURGO or STATSGO. A request past that edge comes back empty rather than approximated.
  • ⚠ Which years it spans, because the covered period is not declared.
  • ⚠ Anything USDA NRCS Soil Data Access does not publish. ParcelOps returns this source as it stands and never fills a blank field from a different one.
  • ⚠ Soil survey context does not replace current field investigation, engineering, or site-specific geotechnical analysis.
