Soil survey area

Ballard and McCracken Counties, Kentucky

Survey Area KY602• Kentucky
The short version

The most common soil here is Grenada, on about 19% of the land: a silt loam, smooth, like flour. Calloway and Loring come next.

About 19% of the land drains well, and 35% stays wet for long stretches; groundwater comes within two feet of the surface under 61% of it.

USDA rates 87% of the land very limited for a standard septic drain field, and 87% very limited for homes with basements. That means extra cost or special design, not that it can't be done.

Worth knowing: 30% of the land floods occasionally or more.

Soil Orders in This Area

The USDA classifies every soil into one of 12 soil orders. Here are the dominant orders found in this survey area.

Alfisols
Moderately weathered forest soils with clay-enriched subsoil. Productive for agriculture, generally good for building and septic.
Inceptisols
Young but developing soils found in mountains and river terraces. Variable properties — check drainage and bedrock depth.
Ultisols
Strongly weathered clay soils of the Southeast. Acidic and naturally low in nutrients. Clay subsoil can slow drainage.
Entisols
Young soils with little development — found on floodplains, dunes, and steep slopes. Properties vary widely by setting.

What This Means

Building & Foundations

About 87% of soils are rated "very limited" for dwellings with basements. Specific challenges include steep slopes, poor drainage in some areas, flood-prone areas. A geotechnical assessment is recommended before building.

Septic Systems

About 87% of soils are rated "very limited" for septic absorption fields. Despite good drainage overall, limitations may stem from shallow bedrock, steep slopes, or seasonal conditions. Engineered or alternative systems are frequently required. Always get a professional perc test before purchasing land that needs septic.

Gardening & Agriculture

Well-drained soils on sloped terrain — good for most plants but watch for erosion. Terracing, contour planting, and mulching help retain moisture and topsoil. Drip irrigation is more effective than sprinklers on slopes.
