Description of soil BC$TF~~~~~N (TIDAL FLAT)
|Profile||Native soil profile
The soil is in native condition (undisturbed by agriculture).
|Kind of material||True Non-soil
This is a true non-soil (e.g. airport or lake).
The water table is always present in the soil.
|Root restrictions||First layer
The growth of plant roots is restricted by the first (uppermost) layer.
|Type of root restricting layer||Salinity
Salinity (conductivity > 4 dS/m)
|Drainage||Very poorly drained
Water is removed from the soil so slowly that the water table remains at or on the surface for the greater part of the time the soil is not frozen. Excess water is present in the soil for the greater part of the time. Groundwater flow and subsurface flow are the major water sources. Precipitation is less important except where there is a perched water table with precipitation exceeding evapotranspiration. Soils have a wide range in available water storage capacity, texture, and depth, and are either Gleysolic or Organic.
|Mode of Deposition||Texture||Chemical properties|
Unconsolidated deposits of clay, silt, sand, or gravel that are well to moderately well sorted and well to moderately well stratified (in some places containing shells). The deposits have settled from suspension in salt or brackish water bodies or have accumulated at their margins through shoreline processes such as wave action and longshore drift. Nonfossiliferous deposits may be judged marine if they are located in an area that may reasonably be considered to have contained salt water at the time the deposits were formed.
Medium (USDA Texture Classes: VFSL,L,SIL,SI,GL,GSIL).
