Description of soil NBSAD1~~~~N (ST. AMAND)

Orthic Luvic Gleysol

The soil is in native condition (undisturbed by agriculture).

The soil material is primarily composed of mineral particles.

The water table is always present in the soil.

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

Undifferentiated

Water is removed from the soil sufficiently slowly in relation to supply, to keep the soil wet for a significant part of the growing season. Excess water moves slowly downward if precipitation is the major supply. If subsurface water or groundwater, or both, is the main source, the flow rate may vary but the soil remains wet for a significant part of the growing season. Precipitation is the main source if available water storage capacity is high; contribution by subsurface flow or groundwater flow, or both, increases as available water storage capacity decreases. Soils have a wide range in available water supply, texture, and depth, and are gleyed phases of well drained subgroups.

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.

Fine (USDA Texture Classes: SC,SIC,C,GSIC).

pH 5.6 - 7.4

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

Fine (USDA Texture Classes: SC,SIC,C,GSIC).
