Description of soil YTCHD~~~~~N (CHADBURN)

General Characteristics
Classification O.MB

Orthic Melanic Brunisol

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 Never

The water table is not present in the soil at any time.

Root restrictions No root restricting layer

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

Type of root restricting layer n/a

Not Applicable

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 Undifferentiated mineral

A sequence of more than three types of genetic mineral materials outcropping on a steep erosional escarpment. This complex class is to be used where units relating to individual genetic materials cannot be delimited separately at the scale of mapping. It may include colluvium derived from the various genetic materials and resting upon the scarp slope.

Medium

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

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 Skeletal

Medium Skeletal (USDA Texture Classes: VGSL, VGL).

Weakly Calcareous

< 6 CaCO3 equivalent (%)
