Description of soil MBMOTt~~~~A (Montgomery)

General Characteristics
Classification GLR.BLC

Gleyed Rego Black Chernozem

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 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.

Parent Materials
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.

Medium

Medium (USDA Texture Classes: VFSL,L,SIL,SI,GL,GSIL).

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.

Moderately Fine

Moderately Fine (USDA Texture Classes: SCL,FSCL,VFSCL,CL,SICL,GSCL,GL,CBCL).

Moderately / Very Strongly Calcareous

6 - 40 CaCO3 equivalent (%)
