Soil survey area

Hempstead County, Arkansas

Survey Area AR057• Arkansas
The short version

The most common soil here is Sacul, on about 14% of the land: a very fine sandy loam, gritty and crumbly. Sawyer and Oktibbeha come next.

About 24% of the land drains well, and 29% stays wet for long stretches; groundwater comes within two feet of the surface under 29% of it.

USDA rates 93% of the land very limited for a standard septic drain field, and 63% very limited for homes with basements. That means extra cost or special design, not that it can't be done.

Worth knowing: 22% of the land floods occasionally or more, and bedrock lies within 40 inches under 2% of it.

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.

Ultisols
Strongly weathered clay soils of the Southeast. Acidic and naturally low in nutrients. Clay subsoil can slow drainage.
Vertisols
High-clay soils that shrink and swell dramatically. Fertile but challenging for foundations and septic systems.
Alfisols
Moderately weathered forest soils with clay-enriched subsoil. Productive for agriculture, generally good for building and septic.
Entisols
Young soils with little development — found on floodplains, dunes, and steep slopes. Properties vary widely by setting.

What This Means

Building & Foundations

About 63% of soils are rated "very limited" for dwellings with basements. Specific challenges include poor drainage in some areas, flood-prone areas. A geotechnical assessment is recommended before building.

Septic Systems

About 93% 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.
