Description of soil MBCWB~~~~~N (Cowan Bay)
| Classification | R.G |
|---|---|
| Profile | Native soil profile The soil is in native condition (undisturbed by agriculture). |
| Kind of material | Mineral The soil material is primarily composed of mineral 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 | Lithic Lithic (consolidated bedrock) |
| 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 | Till (Morainal) Morainal material (till) deposited by glacial ice: a mixture of boulders, sand, silt, and clay. |
Moderately Coarse Moderately Coarse (USDA Texture Classes: VFS,LVFS,CSL,SL,FSL,GSL,CBSL,GFSL). |
