Click to enlarge Podzolic soils are forested soils found primarily on sandy deposits in ecozones (or parts of ecozones) where the mean annual precipitation is above 700 mm. Coniferous-dominated plant communities are the major vegetation type found on Podzolic soils. Podzolic soils have B horizons that are enriched with amorphous material composed of humified organic matter, aluminum and iron. These soils generally have organic surface horizons, a light coloured eluvial horizon (which may be absent), and a reddish to black B horizon with an abrupt upper boundary.
