Description of soil MBMDNs~~~~A (Marsden)
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 | Poorly drained Water is removed so slowly in relation to supply that the soil remains wet for a comparatively large part of the time the soil is not frozen. Excess water is evident in the soil for a large part of the time. Subsurface flow or groundwater flow, or both, in addition to precipitation are the main water sources; there may also be a perched water table, with precipitation exceeding evapotranspiration. Soils have a wide range in available water storage capacity, texture, and depth, and are gleyed subgroups, Gleysols, and Organic soils. |
Mode of Deposition | Texture | Chemical properties | |
---|---|---|---|
Uppermost | Fluviolacustrine Fluviolacustrine |
Medium Medium (USDA Texture Classes: VFSL,L,SIL,SI,GL,GSIL). |
Moderately / Very Strongly Calcareous 6 - 40 CaCO3 equivalent (%) |
Middle | Glaciofluvial Material moved by glaciers and subsequently sorted and deposited by streams flowing from the melting ice. The deposits are stratified and may occur in the form of outwash plains, deltas, kames eskers, and kame terraces. See also glacial drift and till. |
Coarse Skeletal Coarse Skeletal (USDA Texture Classes: VGS, VGLS). |
Moderately / Very Strongly Calcareous 6 - 40 CaCO3 equivalent (%) |
Lowest | Till (Morainal) Morainal material (till) deposited by glacial ice: a mixture of boulders, sand, silt, and clay. |
Moderately Fine Moderately Fine (USDA Texture Classes: SCL,FSCL,VFSCL,CL,SICL,GSCL,GL,CBCL). |
Moderately / Very Strongly Calcareous 6 - 40 CaCO3 equivalent (%) |
