Utilization of Regional Natural Brines for the Indoor Cultivation of <i>Salicornia europaea</i>

Scaling agriculture to the globally rising population demands new approaches for future crop production such as multilayer and multitrophic indoor farming. Moreover, there is a current trend towards sustainable local solutions for aquaculture and saline agriculture. In this context, halophytes are b...
