Description of soil MBDMRds~~~A (Delmar, drained, saline)
| Classification | R.HG |
|---|---|
| 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 | Always The water table is always present in the soil. |
| Root restrictions | First layer The growth of plant roots is restricted by the first (uppermost) layer. |
| Type of root restricting layer | Salinity Salinity (conductivity > 4 dS/m) |
| Drainage | Imperfectly drained Water is removed from the soil sufficiently slowly in relation to supply, to keep the soil wet for a significant part of the growing season. Excess water moves slowly downward if precipitation is the major supply. If subsurface water or groundwater, or both, is the main source, the flow rate may vary but the soil remains wet for a significant part of the growing season. Precipitation is the main source if available water storage capacity is high; contribution by subsurface flow or groundwater flow, or both, increases as available water storage capacity decreases. Soils have a wide range in available water supply, texture, and depth, and are gleyed phases of well drained subgroups. |
| 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. |
Moderately Coarse Moderately Coarse (USDA Texture Classes: VFS,LVFS,CSL,SL,FSL,GSL,CBSL,GFSL). |
Moderately / Very Strongly Calcareous 6 - 40 CaCO3 equivalent (%) |
| Below | 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. |
Very Fine Very Fine (USDA Texture Classes: HC (more than 60% clay). |
Moderately / Very Strongly Calcareous 6 - 40 CaCO3 equivalent (%) |
