Description of soil MBCOC~~~~~N (Cooper Creek)
| Classification | TME.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 | 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 |
| Below | 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:
|
Fine Fine (USDA Texture Classes: SC,SIC,C,GSIC). |
Moderately / Very Strongly Calcareous 6 - 40 CaCO3 equivalent (%) |
