Description of soil MBWIT~~~~~N (Witchai)
| Classification | BRE.SC |
|---|---|
| Profile | Native soil profile The soil is in native condition (undisturbed by agriculture). |
| Kind of material | Unclassified This material was not classified due to an absence of information or an unusual situation, such as rockland or an extremely shallow soil. |
| Water table | Never The water table is not present in the soil at any time. |
| Root restrictions | Sixth layer The growth of plant roots is restricted by the sixth 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 | Lacustrine Sediment, generally consisting of either stratified fine sand, silt, and clay deposited on the lake bed, or moderately-well sorted, stratified sand and coarse materials that consist of near lake shore or beach deposits. These materials have either settled from suspension in bodies of standing fresh water or accumulated at their margins through wave action. |
Fine Fine (USDA Texture Classes: SC,SIC,C,GSIC). |
Moderately / Very Strongly Calcareous 6 - 40 CaCO3 equivalent (%) |
| Middle | Lacustrine Sediment, generally consisting of either stratified fine sand, silt, and clay deposited on the lake bed, or moderately-well sorted, stratified sand and coarse materials that consist of near lake shore or beach deposits. These materials have either settled from suspension in bodies of standing fresh water or accumulated at their margins through wave action. |
Moderately Fine Moderately Fine (USDA Texture Classes: SCL,FSCL,VFSCL,CL,SICL,GSCL,GL,CBCL). |
Extremely Calcareous > 40 CaCO3 equivalent (%) |
| Lowest | Igneous, acidic Igneous, acidic bedrock (dominantly granite) |
