What this means

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

For your garden

Typical topsoil in Burlington County is very strongly acidic: pH 4.6 (most land between 4.0 and 5.8). 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.

Sandy topsoil covers 53% of the land. 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 sand (35% of the land).

64% of the land is moderately well to excessively drained, which suits most garden plants.

For your lawn and yard

37% of the land is in hydrologic group A, where water soaks in fast. Lawns there dry out quickly; deeper, less frequent watering and organic matter help.

A seasonal high water table comes within 18 inches of the surface on 35% 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 99% of the land in Burlington County very limited, <1% somewhat limited and <1% not limited (1% not rated, such as urban land, pits or water).

Statewide, 90% of the land is very limited, so Burlington County is more restrictive than typical.

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 16% of the land (3% occasional, 12% frequent).

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

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.
