Nodaway County, Missouri
The most common soil here is Shelby, on about 33% of the land: a clay loam, firm and a little sticky. Sharpsburg and Lamoni come next.
About 38% of the land drains well, and 36% stays wet for long stretches; groundwater comes within two feet of the surface under 35% of it.
USDA rates 99% of the land very limited for a standard septic drain field, and 42% very limited for homes with basements. That means extra cost or special design, not that it can't be done.
Worth knowing: 16% of the land floods occasionally or more.

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 42% of soils have significant building limitations, while the rest are generally suitable. Check specific sites carefully — conditions vary across the area.
Septic Systems
About 99% 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.
