Description of soil MBWUS1~~~~N (Wuskwatim 1)

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 Third layer

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

Type of root restricting layer Cryic

Cryic (frozen) horizon

Drainage Imperfectly drained

Water is removed from the soil sufficiently slowly in relation to supply, to keep the soil wet for a significant part of the growing season. Excess water moves slowly downward if precipitation is the major supply. If subsurface water or groundwater, or both, is the main source, the flow rate may vary but the soil remains wet for a significant part of the growing season. Precipitation is the main source if available water storage capacity is high; contribution by subsurface flow or groundwater flow, or both, increases as available water storage capacity decreases. Soils have a wide range in available water supply, texture, and depth, and are gleyed phases of well drained subgroups.

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.
