Solonetzic Soils Location
Solonetzic soils cover almost 73 000 km2 (0.7%) of Canada's land area
Solonetzic soils are grassland or grassland-forest transition soils whose features reflect the influence of sodium on soil horizon formation. High sodium contents are inherited from incorporation of marine shale into the parent sediments and sodium can be further concentrated by groundwater flow. The high sodium content is diagnostic for the Bn horizon. The sodium also commonly leads to movement of clay from the Ae to the B horizon, forming a Bnt horizon. The B horizon commonly overlies a C horizon with sodium salts, gypsum, and calcium carbonate (Csk horizon).
The presence of a sodium-enriched B horizon in the rooting zone can cause significant agronomic problems for crop cultivation.This makes it hard for growing crops and other agricultural features.
