Description of soil ONCHD~~~~~A (CHANDOS)
| Classification | O.DYB |
|---|---|
| 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 | Fifth layer The growth of plant roots is restricted by the fifth 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 |
|---|---|---|
| Fluvial These sediments generally consist of gravel and sand with a minor fraction of silt and rarely of clay. The gravels are typically rounded and contain interstitial sand. |
Very Coarse Very Coarse (USDA Texture Classes: VCS,CS,S,GS,CBS). |
Medium Acid to Neutral pH 5.6 - 7.4 |
