Soil survey area

Schleicher County, Texas

Survey Area TX413• Texas
The short version

The most common soil here is Tarrant, on about 36% of the land: a very cobbly silty clay, smooth and very sticky when wet. Tobosa and Cho come next.

About all of the land drains well.

USDA rates all of the land very limited for a standard septic drain field, and 92% very limited for homes with basements. That means extra cost or special design, not that it can't be done.

Worth knowing: 2% of the land floods occasionally or more, and bedrock lies within 40 inches under 69% 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.
Vertisols
High-clay soils that shrink and swell dramatically. Fertile but challenging for foundations and septic systems.

What This Means

Building & Foundations

About 92% of soils are rated "very limited" for dwellings with basements. Specific challenges include shallow bedrock, flood-prone areas. A geotechnical assessment is recommended before building.

Septic Systems

About 100% 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

Drainage is generally favorable for gardening. Adding compost and mulch will improve fertility and water retention. Test your soil's pH before planting — most vegetables prefer 6.0-7.0.
