Umbraquult, Typic

Typic Umbraquults are moderately extensive on the low coastal plains along the Atlantic Ocean. Some of the soils have been drained and cleared and are used as cropland or pasture, but many are used as forest. Umbraquults are among the wettest of the Aquults, and their argillic horizon is not so strongly developed as that in most of the other Aquults. The natural vegetation consisted mostly of water-tolerant trees and herbs.
Aquults are the Ultisols in wet areas where ground water is very close to the surface during part of each year, usually in winter and spring in middle latitudes, and is deep at another time. These soils are mostly grayish or olive in the subsoil and formed mainly in alluvium and marine deposits that are of Pleistocene age or older. Aquults are extensive on the coastal plains in the United States, particularly along the Atlantic Ocean and the Gulf of Mexico. Their slopes are gentle. Most of the soils had and many still have a forest vegetation. Aquults have an ochric or umbric epipedon and an argillic or kandic horizon. Some have a fragipan, and others have plinthite in or below the argillic or kandic horizon.
