Description of soil MBSCR~~~~~N (Screech Creek)

Terric Fibric Organic Cryosol

The soil is in native condition (undisturbed by agriculture).

The soil material is primarily composed of organic particles.

The water table is always present in the soil.

The growth of plant roots is restricted by the third layer.

Cryic (frozen) horizon

Water is removed so slowly in relation to supply that the soil remains wet for a comparatively large part of the time the soil is not frozen. Excess water is evident in the soil for a large part of the time. Subsurface flow or groundwater flow, or both, in addition to precipitation are the main water sources; there may also be a perched water table, with precipitation exceeding evapotranspiration. Soils have a wide range in available water storage capacity, texture, and depth, and are gleyed subgroups, Gleysols, and Organic soils.

This class is used for forest peatcovered or forest peat-filled areas where the water table is at or above the peat surface. The dominant peat materials are shallow to deep mesic to humic forest and fen peat formed in a eutrophic environment resulting from strong water movement from the margins or other mineral sources.

Mesic

pH 5.6 - 7.4

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.

Moderately Fine (USDA Texture Classes: SCL,FSCL,VFSCL,CL,SICL,GSCL,GL,CBCL).
