Description of soil BCNPU~~~~~A (NEPTUNE)

General Characteristics
Classification O.HR

Orthic Humic Regosol

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 Non growing season

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

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 Anthropogenic

Materials modified by people,including those associated with mineral exploitation and waste disposal. They include materials deposited as a result of human activities or geological materials modified artificially so that their physical properties (structure, cohesion, compaction) have been drastically altered. Examples are areas of landfill, spoil heaps, open-pit mines and levelled irrigated areas.


Coarse (USDA Texture Classes: FS,LCS,LS,LFS,GLS,CBLS).

Moderately / Very Strongly Calcareous

6 - 40 CaCO3 equivalent (%)

Below Marine

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.


Coarse (USDA Texture Classes: FS,LCS,LS,LFS,GLS,CBLS).

Medium Acid to Neutral

pH 5.6 - 7.4
