Description of soil BCRUYa~~~~A (RUMSLEY)
| Classification | O.SB |
|---|---|
| Profile | Agricultural soil profile The soil has been disturbed 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 | Well drained Water is removed from the soil readily but not rapidly. Excess water flows downward readily into underlying pervious material or laterally as subsurface flow. Soils have intermediate available water storage capacity (4-5 cm) within the control section, and are generally intermediate in texture and depth. Water source is precipitation. On slopes subsurface flow may occur for short durations, but additions are equaled by losses. |
| Mode of Deposition | Texture | Chemical properties | |
|---|---|---|---|
| Uppermost | Colluvial Massive to moderately-well stratified, nonsorted to poorly sorted sediments with any range of particle sizes from clay to boulders that have reached their present position only by direct, gravity-induced movement. Processes include slow displacements such as creep and solifluction and rapid movements such as earth flows. |
Moderately Coarse Moderately Coarse (USDA Texture Classes: VFS,LVFS,CSL,SL,FSL,GSL,CBSL,GFSL). |
Medium Acid to Neutral pH 5.6 - 7.4 |
| Below | Igneous, acidic Igneous, acidic bedrock (dominantly granite) |
