What this means

What the soils in Hinds County mean for gardens, lawns and septic systems

For your garden

Typical topsoil in Hinds County is strongly acidic: pH 5.3 (most land between 5.1 and 6.2). 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 97% of the land: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is silt loam (94% of the land).

89% of the land is moderately well to excessively drained, which suits most garden plants.

For your lawn and yard

On 67% of the land, 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.

A seasonal high water table comes within 18 inches of the surface on 26% of the land, often in spring. Basements, sump pumps and lawns in low spots feel it first.

For a septic system

For conventional septic absorption fields, NRCS rates 88% of the land in Hinds County very limited, 9% somewhat limited and 0% not limited (3% not rated, such as urban land, pits or water).

That is close to the state as a whole (92% very 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.

Flooding is mapped on 28% of the land (24% occasional, 4% frequent).

Only a licensed site evaluation or perc test at the actual lot decides whether a system is allowed and which design.

Drainage

How long the soil stays wet

The most common drainage class is moderately well drained (58%). 89% of the land is moderately well drained or better, compared with 62% across Mississippi.

Septic absorption fields

NRCS rating for conventional drain fields

The rating looks at the soil from 24 to 60 inches deep: permeability, depth to a seasonal water table or bedrock, flooding and slope. “Very limited” means at least one feature is unfavorable enough that a conventional field is hard to make work.
