Morkill Valley Podzol

Soil Site Details: Morkill Valley 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. Podzols are one of the forest soil types in the Canadian soil classification system, often present in coniferous forests. Podzols generally have a B horizon that is enriched with amorphous material composed mainly of humified organic matter, Al and Fe. 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%). This site is further classified into the Forgetmenot Soil Association. These soils are usually rapidly well-drained, making them prone to moisture deficiencies in the summer. The parent material is made up of deep gravelly fluvial and glacio-fluvial deposits.
