The objective of this project is to develop new agricultural inputs with seaweed discards produced in the food industry, and test their effectiveness to be used both in organic farming, as well as in reconversion and also for sustainable conventional agriculture. For this, both well-known and simple techniques will be used -dehydration and grinding-, as well as other more sophisticated ones such as the elaboration of natural extracts, with the aim of improving the conditions of organically grown orchard, potato and vine crops.
