What this means

What Harney soil means for gardens, lawns and septic systems

For gardens

Typical topsoil in Harney soils is slightly acidic: pH 6.3 (most land between 6.3 and 6.7), the range most vegetables, flowers and lawn grasses prefer.

Loamy topsoil (loam, silt loam and similar) covers 100% of mapped Harney acres: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is silt loam (88% of mapped Harney acres).

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

For lawns and yards

On 100% of mapped acres, rain soaks in slowly (hydrologic groups C and D, including dual groups that are D until drained). Expect runoff and puddles after heavy rain: core-aerate compacted lawns and keep ground sloping away from foundations.

For a septic system

For conventional septic absorption fields, NRCS rates 96% of the acres in mapped Harney soils very limited, 4% 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.
