Description of soil ONBUFSH~~~A (BURFORD)

General Characteristics
Classification O.GBL

Orthic 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 Never

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

Root restrictions Fifth layer

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

Type of root restricting layer Lithic

Lithic (consolidated bedrock)

Drainage Rapidly drained

Water is removed from the soil rapidly in relation to supply. Excess water flows downward if underlying material is pervious. Subsurface flow may occur on steep gradients during heavy rainfall. Soils have low available water storage capacity (2.5-4 cm) within the control section, and are usually coarse textured, or shallow, or both. Water source is precipitation.

Parent Materials
Mode of Deposition Texture Chemical properties
Glaciofluvial

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.

Very Coarse

Very Coarse (USDA Texture Classes: VCS,CS,S,GS,CBS).

Moderately / Very Strongly Calcareous

6 - 40 CaCO3 equivalent (%)
