Typical landscape of a Toisnot soil. The Toisnot series (Typic Fragiaquults) consists of very deep (moderately deep to the fragipan), poorly drained, slowly permeable soils with slow to ponded runoff. They formed in fluvial or marine sediments in the upper Coastal Plain. Slopes range from 0 to 2 percent. Depth to a seasonal high water table (endosaturation) is 0 to 12 inches, primarily in December to April.
Toisnot soils are in shallow depressions, around the heads of drainageways, and on the outer fringe of stream terraces next to the better drained uplands, in the upper Coastal Plain. They occupy the transition areas between soils with contrasting drainage. On some landscapes, these soils extend down shallow drainageways for short distances. Slopes are generally less than 2 percent. Near the type location, the mean annual rainfall is 49 inches and mean annual temperature is 62 degrees F.
Most areas are in mixed forests of hardwoods and pine. Native trees include oak, maple, sweetgum, yellow-poplar, and loblolly pine, with understory plants as sweet bay, myrtle, gallberry, and smilax. Small acreages have been cleared and used for pasture, corn, and soybeans.
Toisnot soils are of small extent along Upper Coastal Plain areas of North Carolina and possibly South Carolina and Virginia.
