Description of soil ONSTC~~~~~A (STEVEN CREEK)

Gleyed Melanic Brunisol

The soil has been disturbed by agriculture.

The soil material is primarily composed of mineral particles.

The water table is present in the soil during the non growing season.

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

Not Applicable

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.

Unconsolidated deposits of clay, silt, sand, or gravel that are well to moderately well sorted and well to moderately well stratified (in some places containing shells). The deposits have settled from suspension in salt or brackish water bodies or have accumulated at their margins through shoreline processes such as wave action and longshore drift. Nonfossiliferous deposits may be judged marine if they are located in an area that may reasonably be considered to have contained salt water at the time the deposits were formed.

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.

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