ENDOAQUEPT, FLUVAQUENTIC
Fluvaquentic Endoaquepts.—These soils have either 0.2 percent or more organic carbon (Holocene age) at a depth of 125 cm below the mineral soil surface or an irregular decrease in organic-carbon content (Holocene age) between a depth of 25 cm and either a depth of 125 cm below the mineral soil surface or a densic, lithic, or paralithic contact, whichever is shallower. They also have slopes of less than 25 percent. These soils are extensive in the United States. They are on flood plains in all parts of the country, except for the coldest and the driest parts. The native vegetation is mostly water-tolerant trees and grasses. Some of these soils are used as forest, and some have been cleared and artificially drained and are used as cropland or pasture.

Center: Typical landscape associated with the soil profile.
Right: Common redoximorphic feature in the subsoil (iron concentration lining cylindrical pore) in a depleted matrix.
