Description of soil MBDFSs~~~~A (Dufresne)
| 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 | Unspecified period The water table is present in the soil during an unspecified period. |
| 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 | Very poorly drained Water is removed from the soil so slowly that the water table remains at or on the surface for the greater part of the time the soil is not frozen. Excess water is present in the soil for the greater part of the time. Groundwater flow and subsurface flow are the major water sources. Precipitation is less important except where there is a perched water table with precipitation exceeding evapotranspiration. Soils have a wide range in available water storage capacity, texture, and depth, and are either Gleysolic or Organic. |
| 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. |
Fine Fine (USDA Texture Classes: SC,SIC,C,GSIC). |
Moderately / Very Strongly Calcareous 6 - 40 CaCO3 equivalent (%) |
