What this means
What the soils in Rowan County mean for gardens, lawns and septic systems
For your garden
Typical topsoil in Rowan County is strongly acidic: pH 5.5 (most land between 5.3 and 6.4). Most vegetables and lawn grasses do best around 6.0 to 7.0, so lime is often needed; blueberries, azaleas and rhododendrons like it as it is.
Loamy topsoil (loam, silt loam and similar) covers 89% of the land: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is sandy clay loam (37% of the land).
90% of the land is moderately well to excessively drained, which suits most garden plants.
For your lawn and yard
Most land is in hydrologic groups B and C, where rain soaks in at a moderate pace.
For a septic system
For conventional septic absorption fields, NRCS rates 54% of the land in Rowan County very limited, 45% somewhat limited and 0% not limited (2% not rated, such as urban land, pits or water).
Statewide, 76% of the land is very limited, so Rowan 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 10% of the land (<1% occasional, 9% 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 (83%). 90% of the land is moderately well drained or better, compared with 68% across North Carolina.

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.
