Description of soil ONFMB~~~~~A (FLAMBOROUGH)

General Characteristics
Classification O.HG

Orthic Humic Gleysol

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 Always

The water table is always present in the soil.
Root restrictions Fourth layer

The growth of plant roots is restricted by the fourth layer.
Type of root restricting layer Undifferentiated

Undifferentiated
Drainage Poorly drained

Water is removed so slowly in relation to supply that the soil remains wet for a comparatively large part of the time the soil is not frozen. Excess water is evident in the soil for a large part of the time. Subsurface flow or groundwater flow, or both, in addition to precipitation are the main water sources; there may also be a perched water table, with precipitation exceeding evapotranspiration. Soils have a wide range in available water storage capacity, texture, and depth, and are gleyed subgroups, Gleysols, and Organic soils.
Parent Materials
Mode of Deposition Texture Chemical properties
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 Coarse

Moderately Coarse (USDA Texture Classes: VFS,LVFS,CSL,SL,FSL,GSL,CBSL,GFSL).

 Moderately / Very Strongly Calcareous

6 - 40 CaCO3 equivalent (%)
