what is salinity? high concentrations of dissolved mineral salts in the soil what are 4 contributing cations to salinity Na+, Ca2+, Mg2+, K+ What is sodicity high concentration of Na+ relative to Ca2+ and Mg2+ when does soil salinization occur? when groundwater containing salt is able to reach the root zone or soil surface where it evaporates and laves an accumulation of salt what are the most common salts in prairie soils? sulphate salts of calcium, magnesium andddd sodium and chloride salts of sodium and magnesium what are the 3 conditions required to create a soil salinity problem? soluble salts in subsoil, groundwater or both, high water tables, plants susceptible to soil salinity how do high water tables contribute to salinity? they carry soluble salts into root zone by capillary action (
