Description of soil ABMKWaa~~~N (MIKKWA)

General Characteristics
Classification ME.OC

Mesic Organic Cryosol

Profile Native soil profile

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

Kind of material Organic

The soil material is primarily composed of organic particles.

Water table Unspecified period

The water table is present in the soil during an unspecified period.

Root restrictions Fourth layer

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

Type of root restricting layer Cryic

Cryic (frozen) horizon

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
Uppermost Sphagnum Peat

These deposits consist of sphagnum or forest peat formed in an ombrotrophic environment caused by the slightly elevated nature of the bog. They tend to be disassociated from nutrient-rich ground water or surrounding mineral soils.

Fibric

Fibric

Medium Acid to Neutral

pH 5.6 - 7.4

Middle Forest Peat

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.

Fibric

Fibric

Undifferentiated

Undifferentiated acidity and/or calcareousness

Lowest Fen Peat

These deposits consist of sedge peat derived primarily from sedges with inclusions of partially decayed stems of shrubs formed in a eutrophic environment due to the close association of the material with mineral-rich waters.

Undifferentiated acidity and/or calcareousness
