often been discussed and studied. But despite intensive research and many projects,
only a few organisms have been found that can be grown with seawater. Thus
the question was asked: How can we grow plants with seawater? (Breckle 2009).
Full-strength seawater can be used to sustainably irrigate only a few special plants,
e.g. Sesuvium, Aster, Salicornia (Ventura and Sagi 2013) – maybe now that
Salicornia salad is becoming quite popular – and Spartina along sandy seashores,
without impairing soil quality provided that sufficient drainage exists. Intensive
agriculture with seawater with high production per surface area is utopian. It was
