Howard County, Missouri
The most common soil here is Lindley, on about 10% of the land: a loam, a balanced mix that crumbles in your hand. Winfield and Menfro come next.
About 34% of the land drains well, and 27% stays wet for long stretches; groundwater comes within two feet of the surface under 21% of it.
USDA rates 96% of the land very limited for a standard septic drain field, and 67% 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 9% 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.
What This Means
Building & Foundations
About 67% of soils are rated "very limited" for dwellings with basements. Specific challenges include steep slopes, poor drainage in some areas, flood-prone areas. A geotechnical assessment is recommended before building.
Septic Systems
About 96% 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.
