Soil in Bessemer, AL

The center of ZIP 35020 is mapped as Urban land: built-over ground without natural soil data. Garden soil here is usually imported or disturbed — test before you plant.

Soil Survey Staff, Natural Resources Conservation Service, USDA. Soil Survey Geographic (SSURGO) Database, via Soil Data Access, accessed 2026-10-29. The soil at the center point of ZIP 35020; soils change within a few hundred feet, so a home soil test (pH, nutrients) is still the best guide.
