Typical Tyner 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 Tyner soil means for gardens, lawns and septic systems

For gardens

Typical topsoil in Tyner soils is moderately acidic: pH 5.9 (most land between 5.8 and 5.9). Many vegetables grow well here, and some gardens benefit from a little lime. Test before adding any.

Sandy topsoil covers >99% of mapped Tyner acres. It drains fast and warms early in spring, but dries out and loses nutrients quickly: mulch, compost and steady watering help. The most common surface texture is loamy sand (98% of mapped Tyner acres).

89% of mapped Tyner acres is excessively or somewhat excessively drained: water moves through fast, so gardens need more frequent watering in dry spells.

For lawns and yards

>99% 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 Tyner 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.
