What this means

What Boyer soil means for gardens, lawns and septic systems

For gardens

Typical topsoil in Boyer soils is slightly acidic: pH 6.5 (most land between 5.8 and 6.5), the range most vegetables, flowers and lawn grasses prefer.

Sandy topsoil covers 63% of mapped Boyer 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 (59% of mapped Boyer acres).

100% of mapped Boyer 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 98% of the acres in mapped Boyer soils very limited, <1% somewhat limited and 0% not limited (2% not rated, such as urban land, pits or water).

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.
