The sansouire

The sansouire is characterized by the high salt content of a non-irrigated soil whose silt is bleached by the rise of salt. Only halophilic plants resist: salicornia, saladella, Obione and soda. The combustion of soda produces crystals formerly used for the manufacture of Marseille soaps or in the manufacture of glass. From the 13th to the 19th century, this plant is harvested and marketed by Camarguais, then it is replaced by chemical soda.
