The Cold Vadose Zone: Hydrological and Ecological Significance of Frozen‐Soil Processes
Approximately 50% of soils in the Northern Hemisphere experience seasonal freezing and thawing, which influences physical, chemical, and biological processes in the vadose zone. Soil freeze–thaw drives mechanical processes, including frost heave and soil aggregate formation and breakdown, and contro...
