Description of soil BC$TF~~~~~N (TIDAL FLAT)

General Characteristics
Classification R.G

Rego Gleysol

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).

Water table Always

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.

Parent Materials
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).
