Soil survey area

Mitchell County, Kansas

Survey Area KS123• Kansas
The short version

The most common soil here is Harney, on about 46% of the land: a silt loam, smooth, like flour. Roxbury and Mento come next.

About 91% of the land drains well.

USDA rates 73% of the land very limited for a standard septic drain field, and 34% very limited for homes with basements. That means extra cost or special design, not that it can't be done.

Worth knowing: 10% of the land floods occasionally or more, and bedrock lies within 40 inches under 20% 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.

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.
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.

What This Means

Building & Foundations

About 34% of soils have significant building limitations, while the rest are generally suitable. Check specific sites carefully — conditions vary across the area.

Septic Systems

About 73% 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.
