Soil survey area

Roberts County, Texas

Survey Area TX393• Texas
The short version

The most common soil here is Mobeetie, on about 14% of the land: a fine sandy loam, gritty and crumbly. Pep and Potter come next.

About 99% of the land drains well.

USDA rates 46% of the land very limited for a standard septic drain field, and 28% very limited for homes with basements. That means extra cost or special design, not that it can't be done.

Worth knowing: 9% of the land floods occasionally or more, and bedrock lies within 40 inches under 12% of it.

Soils change over short distances, so look up an address below for the soil at that exact spot and the reasons behind each rating.

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.

Mollisols
Fertile grassland soils with thick, dark topsoil. Among the best for agriculture, building, and gardening.
Inceptisols
Young but developing soils found in mountains and river terraces. Variable properties — check drainage and bedrock depth.
Alfisols
Moderately weathered forest soils with clay-enriched subsoil. Productive for agriculture, generally good for building and septic.
Aridisols
Dry-climate soils with low organic matter. Often have caliche layers that make excavation difficult. Low shrink-swell is good for foundations.
Entisols
Young soils with little development — found on floodplains, dunes, and steep slopes. Properties vary widely by setting.

What This Means

Building & Foundations

About 28% of soils have significant building limitations, while the rest are generally suitable. Check specific sites carefully — conditions vary across the area.

Septic Systems

About 46% of soils have significant septic limitations, while others are more suitable. A perc test is essential — conditions vary across the area.

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.
