Cryosolic soils occupy about 3 672 000 km2 (about 40%) of Canada's land area.
These soils have permafrost (permanently frozen material) within one metre of the surface. As permafrost is a barrier to roots and water, the active layer above it may become a saturated, semifluid material in spring. Commonly the permafrost layer near the surface contains abundant ice. Melting of ice and frozen materials, resulting from disturbance of the surface vegetation (boreal forest or tundra), may cause slumping of the soil and disruption of roads, pipelines and buildings.
Since these soils are all frozen, its hard to use the soils for agricultural uses. But, sometimes its mixed with other soils to firm them up or create a better ground for planting
