Swedish Researchers develop ‘electronic soil’ that speeds up plant growth

Researchers from Linköping University in Sweden developed a ‘bioelectronic soil’ that can speed up the growth of plants in hydroponic spaces, or farms that grow plants without soil in environments made up of mostly water and a place for roots to attach. After integrating the engineered ‘eSoil’ into the framework where seedlings grow, researchers discovered that sending electrical signals through the soil made plants grow 50 percent more on average.
