Typical Acuff profile

Texture and pH by depth

Depth to scale. More strongly shaded layers hold more clay. Horizon names are the soil survey's (A = topsoil, B = subsoil, C = parent material).

What this means

What Acuff soil means for gardens, lawns and septic systems

For gardens

Typical topsoil in Acuff soils is neutral: pH 7.2, the range most vegetables, flowers and lawn grasses prefer.

Loamy topsoil (loam, silt loam and similar) covers >99% of mapped Acuff acres: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is loam (91% of mapped Acuff acres).

100% of mapped Acuff acres is moderately well to excessively drained, which suits most garden plants.

For lawns and yards

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 0% of the acres in mapped Acuff soils very limited, >99% somewhat limited and 0% not limited.

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