Abstract
Evaporation from a salty soil generates salt accumulation near the surface with the subsequent deterioration of the soil quality. Salinization mechanisms are poorly understood despite their global impact. Vapor flux and solute transport were studied under evaporation conditions. Laboratory experiments consisted of open sand and silt columns initially saturated with epsomite (MgSO4 7H2O) or halite (NaCl) solutions. Salt precipitation occurred only above the evaporation front, which occupied a ver...
