Description of soil MBPHG1~~~~N (Pemichigamau 1)
| Classification | FI.OC |
|---|---|
| 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 | Third layer The growth of plant roots is restricted by the third 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. |
| 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. |
Mesic Mesic |
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 |
Extremely / Strongly Acidic pH < 5.6 |
| Lowest | Undifferentiated mineral A sequence of more than three types of genetic mineral materials outcropping on a steep erosional escarpment. This complex class is to be used where units relating to individual genetic materials cannot be delimited separately at the scale of mapping. It may include colluvium derived from the various genetic materials and resting upon the scarp slope. |
Medium Medium (USDA Texture Classes: VFSL,L,SIL,SI,GL,GSIL). |
Moderately / Very Strongly Calcareous 6 - 40 CaCO3 equivalent (%) |
