Soils: The underlying geology of this area is classified as Alluvium of Pleistocene/Holocene origin and consists of undifferentiated Quaternary sediments of varying thickness including siliciclastics, organics and freshwater carbonates. The siliciclastics are light gray, tan, brown to black, unconsolidated to poorly consolidated, clean to clayey, silty, unfossiliferous, variably organic-bearing sands to blue green to olive green, poorly to moderately consolidated, sandy, silty clays. Organics occur as plant debris, roots, disseminated organic matrix and beds of peat. Freshwater carbonates, often referred to as marls in the literature, are scattered.

The primary soil types in the collection area are classified as Rutlege, Pickney and Pamlico soils, frequently flooded. The Rutlege series comprises very deep, very poorly drained persistently wet soils on flats, depressions and floodplains where shallow ponding is common. They are of marine or fluvial sediment origin. Thickness of these loamy sandy soils is greater than 1.5 meters and a reaction from extremely acid to strongly acid. The Pickney Series consists of very deep, very poorly drained soils. Permeability is rapid. These nearly level soils have negligible runoff and were formed by marine or fluvial sediments in the lower coastal plain on flats, depressions, stream terraces, and flood plains. Slopes range from 0 to 2 percent. The soils of this series are loamy fine sand that is very friable and extremely acid in the upper 0-25 cm. The lower strata are similar, while the lower strata from 0.8-2 meters are comprised of fine sand. The Pamlico series consists of very poorly drained soils that formed in decomposed organic material underlain by dominantly sandy sediment. The soils are on nearly level flood plains, bays, and depressions of the Coastal Plain. Slopes are less than 1 percent. Pamlico soils have 0.4-1.3 meters of organic material over dominantly sandy sediments. Reaction is extremely in the organic layers and ranges from extremely acid to strongly acid in the underlying mineral layers.
