What this means

What the soils in Rutherford County mean for gardens, lawns and septic systems

For your garden

Typical topsoil in Rutherford County is moderately acidic: pH 5.8 (most land between 5.6 and 7.3). Many vegetables grow well here, and some gardens benefit from a little lime. Test before adding any.

Loamy topsoil (loam, silt loam and similar) covers 85% of the land: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is silt loam (54% of the land).

78% of the land is moderately well to excessively drained, which suits most garden plants.

For your lawn and yard

On 64% of the land, rain soaks in slowly (hydrologic groups C and D, including dual groups that are D until drained). Expect runoff and puddles after heavy rain: core-aerate compacted lawns and keep ground sloping away from foundations.

For a septic system

For conventional septic absorption fields, NRCS rates 70% of the land in Rutherford County very limited, 16% somewhat limited and 0% not limited (14% not rated, such as urban land, pits or water).

Statewide, 82% of the land is very limited, so Rutherford County is less restrictive than typical.

Where the soil is very limited (slow permeability, a high water table, flooding, shallow bedrock or steep slopes), alternative systems such as mound or sand-filter designs are common and cost more.

Flooding is mapped on 12% of the land (9% occasional, 3% frequent).

Only a licensed site evaluation or perc test at the actual lot decides whether a system is allowed and which design.

Drainage

How long the soil stays wet

The most common drainage class is well drained (73%). 78% of the land is moderately well drained or better, compared with 85% across Tennessee.

Septic absorption fields

NRCS rating for conventional drain fields

The rating looks at the soil from 24 to 60 inches deep: permeability, depth to a seasonal water table or bedrock, flooding and slope. “Very limited” means at least one feature is unfavorable enough that a conventional field is hard to make work.
