Urban farming

Researchers from Linköping University have made a significant breakthrough in hydroponics by introducing a novel cultivation substrate that enhances the growth of barley seedlings. According to a study featured in the journal PNAS, the innovation lies in an electrically conductive "soil" designed specifically for soilless cultivation. The study reveals that when the root system of barley seedlings is electrically stimulated through this pioneering substrate, the growth is boosted by an impressive 50%, highlighting the potential of this advancement in agricultural practices.
