Description of soil ONBOOT~~~~A (BOOKTON)

General Characteristics
Classification BR.GBL

Brunisolic Gray Brown Luvisol

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 Fourth layer

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

Type of root restricting layer Compact Till

Compact (Basal) Till

Drainage Well drained

Water is removed from the soil readily but not rapidly. Excess water flows downward readily into underlying pervious material or laterally as subsurface flow. Soils have intermediate available water storage capacity (4-5 cm) within the control section, and are generally intermediate in texture and depth. Water source is precipitation. On slopes subsurface flow may occur for short durations, but additions are equaled by losses.

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).

Medium Acid to Neutral

pH 5.6 - 7.4

Below Till (Morainal)

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

Medium

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

Moderately / Very Strongly Calcareous

6 - 40 CaCO3 equivalent (%)
