The soil profile above consists of an 8 cm (3.14 inches) layer of peat and/or mucky peat underlain by a 1 cm (0.4 inches) layer of muck. The remaining soil layers are sandy soil material. In LRRs R, W, X, and Y, observations would begin below the peat, mucky peat, and muck layers (9 cm). In LRRs, F, G, H, and M, observations would start at the actual soil surface. In all remaining LRRs, observations would begin at the muck surface (8 cm).
This soil is in the Duckston soil series. The Duckston series (Typic Psammaquents) consists of poorly drained sands near the Lower and Mid-Atlantic coast. They have very slow runoff and very rapid permeability above the water table. The water table fluctuates in relation to the tides and the surface is flooded following heavy rains or high storm tides. At the time of observation, the water table was at a depth of 43 cm.
Duckston soils are mainly in shallow depressions between coastal dunes and on nearly level flats between the dunes and marshes generally at elevations less than 5 feet above mean tide level. Slopes are typically less than 2 percent and surfaces are plane to concave. The soil formed in sandy sediments reworked by waves and wind. Average annual precipitation near the type location is about 48 inches and mean annual temperature about 62 degrees F. The soils are periodically flooded with salt water; salinity is variable according to length of time since last flooding.
Vegetation is a coastal shrub plant community. Locally, a maritime forest exists on a minor acreage of the soil. Duckston soils are of moderate extent along the Lower and Mid-Atlantic coast in Florida, Georgia, South Carolina, North Carolina, and Virginia.
