Description of soil ONDOO~~~~~A (DOURO)
| Classification | O.MB |
|---|---|
| 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 | Third layer The growth of plant roots is restricted by the third 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 |
|---|---|---|
| Till (Morainal) Morainal material (till) deposited by glacial ice: a mixture of boulders, sand, silt, and clay. |
Medium Skeletal Medium Skeletal (USDA Texture Classes: VGSL, VGL). |
Moderately / Very Strongly Calcareous 6 - 40 CaCO3 equivalent (%) |
