Description of soil MBCWF~~~~~A (Crawford)

Gleyed Black Chernozem

The soil has been disturbed by agriculture.

The soil material is primarily composed of mineral particles.

The water table is present in the soil during an unspecified period.

The growth of plant roots is not restricted by any soil layer.

Not Applicable

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.

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 (USDA Texture Classes: VFS,LVFS,CSL,SL,FSL,GSL,CBSL,GFSL).

6 - 40 CaCO₃ equivalent (%)

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 (USDA Texture Classes: VGS, VGLS).

< 6 CaCO₃ equivalent (%)

Morainal material (till) deposited by glacial ice: a mixture of boulders, sand, silt, and clay.

Very Fine (USDA Texture Classes: HC (more than 60% clay).

< 6 CaCO₃ equivalent (%)
