Soil freeze thaw

WebFeb 16, 2024 · The freeze-induced upward redistribution and enrichment of soil water and salt caused the rise and expansion of the soil salification layer, which was the main source of explosive accumulations of surface salt in springtime, and the FT processes contributed to the surface soil salinisation and alkalisation. Seasonally freeze-thaw (FT) processes … WebJan 31, 2011 · Latent heat flux displayed distinctly better correlation with unfrozen soil water content during the freezing and thawing stages than during the completely frozen and thawed stages. This implies that the diurnal cycle of unfrozen soil water, resulting from diurnal freeze/thaw cycles at the surface, has a significant impact on latent heat flux.
