What this means

What Valentine soil means for gardens, lawns and septic systems

For gardens

Typical topsoil in Valentine soils is slightly acidic: pH 6.5, the range most vegetables, flowers and lawn grasses prefer.

Sandy topsoil covers 100% of mapped Valentine 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 fine sand (94% of mapped Valentine acres).

100% of mapped Valentine acres is excessively or somewhat excessively drained: water moves through fast, so gardens need more frequent watering in dry spells.

For lawns and yards

100% 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 100% of the acres in mapped Valentine 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.
