Shelby County land and soils

Steep, wind-deposited loess ridges along the Missouri River — some of the most erodible and most botanically distinctive ground in the Midwest.

Ida–Monona–Napier silt loams, deep and fine-textured, that gully quickly on exposed slopes and shed water fast.

Moisture: Dry to very dry on south- and west-facing ridges, mesic in the draws and toe slopes.
