What this means
What the soils in Kenton County mean for gardens, lawns and septic systems
For your garden
Typical topsoil in Kenton County is moderately acidic: pH 6.0 (most land between 5.5 and 6.5). 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 77% of the land: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is silty clay loam (38% of the land).
93% of the land is moderately well to excessively drained, which suits most garden plants.
For your lawn and yard
On 86% 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 91% of the land in Kenton County very limited, <1% somewhat limited and 0% not limited (9% not rated, such as urban land, pits or water).
Statewide, 79% of the land is very limited, so Kenton County is more 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 5% of the land (4% occasional, <1% 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 (69%). 93% of the land is moderately well drained or better, compared with 89% across Kentucky.

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.

- Kenton County, Kentucky (FIPS 21117): 103,747 acres of mapped land, 1,814 acres of open water excluded. State comparisons pool all mapped land in Kentucky.
- Method
- Shares are by mapped land area: each map unit’s acres in the county times each soil component’s percentage. Open water is excluded. Topsoil values use the first mineral horizon of each component. Full methodology.
