About Soil in Hamblen County, Tennessee
Typical Tennessee Acidity and Texture
Hamblen County's soil profile shows a pH of 5.32, which aligns closely with the Tennessee state average of 5.35. This remains much more acidic than the national median of 6.5, suggesting most local soils need lime for traditional gardening. While specific taxonomic orders are not listed here, the chemical profile is very representative of the region.
Heavy Silt and Clay Mix
The soil composition is 45.7% silt and 24.2% clay, with sand making up the remaining 27.0%. This creates a dense texture that is excellent at holding onto nutrients but can be difficult to work when it is too dry or too wet. Managing this soil requires patience to avoid damaging the structure through improper tilling.
Improving Organic Matter for Resilience
Organic matter content is 1.50%, falling below the state average of 2.44% and the national 2.0% benchmark. The available water capacity is 0.161 in/in, slightly trailing the state average of 0.171. Consistent use of cover crops or organic mulch can help improve these numbers and protect your plants from drying out.
Understanding Local Soil Scores
Hamblen County has a soil score of 28.6, which is lower than the state average of 38.5. While specific drainage and hydrologic group data are not available, this score suggests some limitations for intensive agriculture or construction. Local land managers should conduct site-specific tests to understand how water moves through their property.
