Description of soil QCTNH90000N (TERRES NOIRES, HUMIQUE)
| Classification | TY.H |
|---|---|
| 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 | No root restricting layer The growth of plant roots is not restricted by any soil layer. |
| Type of root restricting layer | n/a Not Applicable |
| Drainage | Very poorly drained Water is removed from the soil so slowly that the water table remains at or on the surface for the greater part of the time the soil is not frozen. Excess water is present in the soil for the greater part of the time. Groundwater flow and subsurface flow are the major water sources. Precipitation is less important except where there is a perched water table with precipitation exceeding evapotranspiration. Soils have a wide range in available water storage capacity, texture, and depth, and are either Gleysolic or Organic. |
| Mode of Deposition | Texture | Chemical properties |
|---|---|---|
| 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. |
