Soil Order Of North Dakota

Soil / Sub OrderLocationCharacteristics
Mollisols/Ustolls, Udolls, and AquollsThey are found throughout the state.1. Ustolls are the more or less freely drained Mollisols of sub-humid to semiarid climates. It is prone to drought.
2. Udolls are the more or less freely drained Mollisols of humid climates.
3. Aquolls are the wet Mollisols.
Entisols/Orthents, Aquents, and FluventsOrthents and Fluvents in the Northwestern great plains, and Aquents in the northern glaciated plains1. Orthents are found on the recent erosional surface.
2. Fluvents are the more or less freely drained Entisols that formed in recent water-deposited sediments
3. Aquents are the wet Entisols
Alfisols/UstalfsIn a small part of northwestern great plains1. Ustalfs have a ustic soil moisture regime.
Vertisols/AquertsIn the Lake Agassiz Plain1. Aquerts are wet clayey soils. They have aquic conditions at or near the soil surface for extended periods during the year but also are dry enough in normal years for cracks to open during some periods.
