Description of soil MBMCC~~~~~N (McClintock 2)

General Characteristics
Classification FI.OC

Fibric 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 Always

The water table is always present in the soil.

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 Poorly drained

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.

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

Extremely / Strongly Acidic

pH < 5.6

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.

Mesic

Mesic

Medium Acid to Neutral

pH 5.6 - 7.4

Lowest Glaciolacustrine

Used where there is evidence that the lacustrine materials were deposited in contact with glacial ice. One of the following characteristics must be present:

  • kettles or an otherwise irregular surface that is neither simply the result of normal settling and compaction in silt nor the result of piping
  • slump structures resulting from loss of support caused by melting of retaining ice
  • presence of numerous ice-rafted stones in the lacustrine silts.

Fine

Fine (USDA Texture Classes: SC,SIC,C,GSIC).

Moderately / Very Strongly Calcareous

6 - 40 CaCO3 equivalent (%)
