Several million hectares of soils of the southeastern United States are subject to inundation by tidal action. The influence of seawater is reflected in the higher proportions of Na and Mg in these soils than in surrounding upland soils or soils in fresh water marshes. Rise in sea level and subsidence of some coastal areas have combined to submerge soils. Diagnostic features such as argillic and spodic horizons were formed prior to submergence. Sulfides have accumulated in some soils. Other soils have features resulting from continuous saturation of sediments deposited in water. Organic materials have accumulated over extensive areas. Additions to Soil Taxonomy are proposed for further testing, including subgroups of Hydraquents and Sulfaquents and halic great groups of Alfisols, Entisols, and Histosols. Field observations indicate a need for refinement of the definition of sulfidic materials. Soil surveys of tidal areas are designed to meet the needs of potential users.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
