What this means
What Edneyville soil means for gardens, lawns and septic systems
For gardens
Typical topsoil in Edneyville soils is strongly acidic: pH 5.3 (most land between 5.0 and 5.3). 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 >99% of mapped Edneyville acres: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is gravelly fine sandy loam (37% of mapped Edneyville acres).
100% of mapped Edneyville acres is moderately well to excessively drained, which suits most garden plants.
For lawns and yards
69% of mapped acres is in hydrologic group A, where water soaks in fast. Lawns there dry out quickly; deeper, less frequent watering and organic matter help.
For a septic system
For conventional septic absorption fields, NRCS rates >99% of the acres in mapped Edneyville soils very limited, 0% somewhat limited and 0% not limited.
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.
Only a licensed site evaluation or perc test at the actual lot decides whether a system is allowed and which design.
