Inman soil series

What this means

What Inman soil means for gardens, lawns and septic systems

For gardens

Typical topsoil in Inman soils is slightly acidic: pH 6.2 (most land between 6.2 and 6.5), the range most vegetables, flowers and lawn grasses prefer.

Loamy topsoil (loam, silt loam and similar) covers 89% of mapped Inman acres: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is flaggy silty clay loam (78% of mapped Inman acres).

>99% of mapped Inman acres is moderately well to excessively drained, which suits most garden plants.

For lawns and yards

On >99% 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 >99% of the acres in mapped Inman 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.
