Description of soil BCSTL09~~~N (STEEPLAND 2)
| Classification | O.EB |
|---|---|
| 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 | Never The water table is not present in the soil at any time. |
| 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 | Rapidly drained Water is removed from the soil rapidly in relation to supply. Excess water flows downward if underlying material is pervious. Subsurface flow may occur on steep gradients during heavy rainfall. Soils have low available water storage capacity (2.5-4 cm) within the control section, and are usually coarse textured, or shallow, or both. Water source is precipitation. |
| Mode of Deposition | Texture | Chemical properties | |
|---|---|---|---|
| Uppermost | 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 Skeletal Medium Skeletal (USDA Texture Classes: VGSL, VGL). |
Medium Acid to Neutral pH 5.6 - 7.4 |
| Below | Undifferentiated Bedrock, undifferentiated |
