Description of soil ONMATHR~~~A (MALTON)
| Classification | O.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 | Third layer The growth of plant roots is restricted by the third layer. |
| Type of root restricting layer | Compact Till Compact (Basal) Till |
| 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 | Glaciolacustrine Used where there is evidence that the lacustrine materials were deposited in contact with glacial ice. One of the following characteristics must be present:
|
Moderately Fine Moderately Fine (USDA Texture Classes: SCL,FSCL,VFSCL,CL,SICL,GSCL,GL,CBCL). |
Moderately / Very Strongly Calcareous 6 - 40 CaCO3 equivalent (%) |
| Below | Till (Morainal) Morainal material (till) deposited by glacial ice: a mixture of boulders, sand, silt, and clay. |
Fine Fine (USDA Texture Classes: SC,SIC,C,GSIC). |
Weakly Calcareous < 6 CaCO3 equivalent (%) |
