In some crops the quantity of absorbed salts proved to be strongly influenced by concentration in substrate, in other crops much less so. Ca proportion of total absorbed cations limited absorption, whereas salt uptake was favoured by higher temperatures.
The possibility of limiting absorption was less, the higher the proportion of Ca (or the relation divalent/monovalent cations) in the plant. Salt tolerance of crops seemed to be related to the relation Ca/other cations in the plant.
