Inceptisols are soils that exhibit minimal horizon development. They are more developed than Entisols, but still lack the features that are characteristic of other soil orders.

Inceptisols are widely distributed and occur under a wide range of ecological settings. They are often found on fairly steep slopes, young geomorphic surfaces, and on resistant parent materials. Land use varies considerably with Inceptisols. A sizable percentage of Inceptisols are found in mountainous areas and are used for forestry, recreation, and watershed.

With recent taxonomic changes, Inceptisols now occupy an estimated 17% of the global ice-free land area, the largest of any soil order. In the US, they occupy ~9.7% of the land area. Inceptisols support ~20% of the world's population, also the largest percentage of any of the soil orders.

Inceptisols are divided into 7 suborders: Aquepts, Anthrepts, Gelepts, Cryepts, Ustepts, Xerepts, and Udepts. Click here for more information about these suborders. Click here to view a map of their distribution in the US.
