Description of soil ABBWFxt~~~N (BAWLF)

General Characteristics
Classification R.BLC

Rego Black Chernozem

Profile Native soil profile

The soil is in native condition (undisturbed 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 Second layer

The growth of plant roots is restricted by the second layer.

Type of root restricting layer Salinity

Salinity (conductivity > 4 dS/m)

Drainage Moderately well drained

Water is removed from the soil somewhat slowly in relation to supply. Excess water is removed somewhat slowly due to low perviousness, shallow water table, lack of gradient, or some combination of these. Soils have intermediate to high water storage capacity (5-6 cm) within the control section and are usually medium to fined textured. Precipitation is the dominant water source in medium to fine textured soils; precipitation and significant additions by subsurface flow are necessary in coarse textured soils.

Parent Materials
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:

  • kettles or an otherwise irregular surface that is neither simply the result of normal settling and compaction in silt nor the result of piping
  • slump structures resulting from loss of support caused by melting of retaining ice
  • presence of numerous ice-rafted stones in the lacustrine silts.

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.

Moderately Fine

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