Soil survey area

Wichita County, Kansas

Survey Area KS203• Kansas
The short version

The most common soil here is Richfield, on about 51% of the land: a silt loam, smooth, like flour. Ulysses and Buffalo Park come next.

About 99% of the land drains well.

USDA rates 78% of the land very limited for a standard septic drain field, and 9% very limited for homes with basements. That means extra cost or special design, not that it can't be done.

Worth knowing: 1% of the land floods occasionally or more, and bedrock lies within 40 inches under 2% 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.
Entisols
Young soils with little development — found on floodplains, dunes, and steep slopes. Properties vary widely by setting.
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.
Vertisols
High-clay soils that shrink and swell dramatically. Fertile but challenging for foundations and septic systems.

What This Means

Building & Foundations

Most soils are generally favorable for residential construction. Standard foundations are usually viable, though site-specific evaluation is always recommended.

Septic Systems

About 78% 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.
