New Delhi,(PTI) Scientists have developed an electrically conductive “soil” which they say can lead to 50 per cent more growth of barley seedlings on average in 15 days.
This soilless cultivation method, known as hydroponics, uses a root system that is stimulated electrically through a new cultivation substrate.
“The world population is increasing, and we also have climate change. So it’s clear that we won’t be able to cover the food demands of the planet with only the already existing agricultural methods,” said Eleni Stavrinidou, an associate professor at the Linkoping University in Sweden.
