What this means
What Devol soil means for gardens, lawns and septic systems
For gardens
Typical topsoil in Devol soils is moderately acidic: pH 6.0 (most land between 6.0 and 6.7). Many vegetables grow well here, and some gardens benefit from a little lime. Test before adding any.
Sandy topsoil covers 65% of mapped Devol 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 (38% of mapped Devol acres).
100% of mapped Devol acres is moderately well to excessively drained, which suits most garden plants.
For lawns and yards
90% 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 88% of the acres in mapped Devol soils very limited, 0% somewhat limited and 0% not limited (12% 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.
