Campbell River Podzol*

Soil Site Details: Campbell River Podzol

Soils on this site are classified as Podzols. Many would consider the Podzols to be the most visually striking soils in Canada. Podzols are one of the most common soils found under coniferous (evergreen) forests.

Technical Description
The soil at this site is of the Podzolic Order. Podzol soils are one of the forest soil types in the Canadian soil classification system, often present in coniferous forest. Podzols generally have a B horizon that is enriched with amorphous material composed mainly of humified organic matter, Al and Fe. The soil at this site falls into the Humo-Ferric Podzol Great Group. The diagnostic horizon is a Bf horizon thicker than 10 cm, that is reddish in colour and enriched with Fe/Al. It has a relatively low organic C content (0.5-5%). It is a Bose Duric Humo-Ferric Podzol. This soils is described as moderately to well-drained, with up to 10 cm of organic forest litter on the soil surface. The parent material is made up of glacial till.
