North Dakota Soil Surveys

53 survey areas

North Dakota has 53 USDA soil survey areas covering a wide range of landscapes and soil conditions. The most common soil order is Mollisols — grassland soils with a thick, dark, fertile topsoil rich in organic matter, making up roughly 84% of surveyed soils. Entisols — young soils with little profile development, often on floodplains or steep slopes account for another 9%.

In terms of drainage, 51% of North Dakota soils are classified as well drained. About 21% of soils have some form of poor drainage, which is important to consider for septic systems and foundations. Drainage class affects everything from septic system design to basement feasibility to garden planning.

Soil Types

Mollisols

84% of surveyed soils

Fertile grassland soils with thick, dark topsoil. Among the best for agriculture, building, and gardening.

Entisols

9% of surveyed soils

Young soils with little development — found on floodplains, dunes, and steep slopes. Properties vary widely by setting.

Vertisols

3% of surveyed soils

High-clay soils that shrink and swell dramatically. Fertile but challenging for foundations and septic systems.

Inceptisols

1% of surveyed soils

Young but developing soils found in mountains and river terraces. Variable properties — check drainage and bedrock depth.
