About Soil in Bradley County, Tennessee

Bradley’s Strong Acidic Foundation

Bradley County soil shows an average pH of 5.17, which is more acidic than the Tennessee average of 5.35. This level sits well below the national median of 6.5, often requiring lime for traditional vegetable gardening.

A Balanced Mix of Soil Particles

The soil contains 26.8% sand, 47.2% silt, and 22.0% clay, a combination often referred to as variable in texture. This mixture provides a middle-ground for drainage and nutrient storage.

Moderate Fertility and Water Access

Organic matter levels at 1.96% are slightly below the state average of 2.44%. Additionally, the water storage capacity of 0.157 in/in is lower than the Tennessee benchmark of 0.171 in/in, requiring more frequent watering.

Local Hydrology and Drainage Variability

Official drainage classes and hydrologic groups for the dominant soil units remain unclassified in recent surveys. Growers typically find that Bradley’s varied topography creates pockets of both quick-draining and heavy-holding land.

Growing Options in Zone 7b

With a soil score of 30.1, Bradley County is well-suited for Zone 7b staples like peppers and ornamental shrubs. Adding compost can help bridge the gap in organic matter to create a more resilient garden.
