Sódio e cloro em Braun-Blanquet (1932)

The edaphically limited saline soils owe their origin chiefly to the world’s salt-storage basin of the seas. Consequently they are strongly influenced by the chemical composition of the sea water, and they are rich in sodium and chlorine. Of the salts dissolved in seawater about 80 per cent is sodium chloride. (Braun-Blanquet 1932:191)

Determination of Chloride Content.—According to Lagatu and Sicard (1911), the fluctuations of the chlorine content of the soil calculated on the basis of 100 parts of air-dried or moist soil give consistent results. Calculated on the basis of dry or moist earth, the sodium chloride content of the lagoon soils near Montpellier increases constantly down to a depth of 2.5 m., as is shown in the accompanying figure (107).
