Kamloops Solonetz

Soil Site Details: Kamloops Solonetz

Soils on this site are Solonetzic. These soils have been influenced by salt accumulation. Very unique plant communities have adapted to live in these high-salt (saline) conditions!

Technical Description
This soil at this grassland site is in the Solonetzic Order. Solonetzic soils occur in the semi-arid interior plains of BC in association with Chernozemic soils (to a lesser extent with Luvisols and Gleysols). They have B horizons that are very hard when dry and swell to a sticky mass of very low permeability when wet. The diagnostic horizon of this soil is a Bn horizon where the ratio of exchangeable Ca to Na/Mg is low (<1:10). This site has lacustrine parent material (saline). PDF with details: No further details
