Most of the cultivated plants come from the halophyte family. These plants can be irrigated with salt water. The ProTerra uses the water from the fish tanks as it is already enriched with organic matter. Additional fertilization is not required.
But not only salt water is needed. At least for the employees freshwater is needed. This is produced by means of a desalination plant. The used water is used for irrigation.
Via a drip irrigation system, e.g. Moringa trees, Andreas bread trees, sea buckthorn hedges and quinoa fields irrigated.
