Dawson Creek Luvisol

Soil Site Details: Dawson Creek Luvisol

Soils on this site are Luvisols. Over long periods of time, fine clay particles have slowly washed from the surface and accumulated deeper into these soils. The name Luvisol originated from the Latin word luo meaning to wash.

Technical Description
This soil is in the Luvisolic Order. Luvisols generally have light-coloured A and B horizons, with an important textural contrast between the two. Clays have eluviated from the A horizon(s) down into the B (illuvial) horizons due to lessivage, or the physical transfer of clays down the profile from vertical water movement. The diagnostic horizon of this soil is a Bt horizon (illuvial, enriched in silicate clay). This site has glaciall (morainal) parent material. The soil at this site falls into the Orthic Gray Luvisol Subgroup. There are well-developed Ae and Bt horizons with a thin (< 5 cm) mineral-organic surface horizon (Ah). These soil textures range from loam to clay loam. PDF with details: 23_Alcan.pdf
