What this means

What Ramsey soil means for gardens, lawns and septic systems

For gardens

Typical topsoil in Ramsey soils is very strongly acidic: pH 5.0 (most land between 4.5 and 5.0). Most vegetables and lawn grasses do best around 6.0 to 7.0, so lime is often needed; blueberries, azaleas and rhododendrons like it as it is.

Loamy topsoil (loam, silt loam and similar) covers 96% of mapped Ramsey acres: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is loam (39% of mapped Ramsey acres).

>99% of mapped Ramsey acres is excessively or somewhat excessively drained: water moves through fast, so gardens need more frequent watering in dry spells.

For lawns and yards

On 96% 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 Ramsey soils very limited, 0% somewhat limited and 0% not limited (4% 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.
