Context: Researchers introduced a ground-breaking study on “electronic soil” (eSoil) in hydroponics, offering the potential for sustainable urban agriculture and food security.
- eSoil is an electrically conductive growth substrate derived from cellulose and a conductive polymer (PEDOT).
- It stimulates plant roots and the growth environment with low power, providing a safer and environmentally friendly alternative to traditional methods.
- eSoil works by electrically stimulating plant roots.
- This promotes effective and sustainable development, expanding the range of crops that can be grown hydroponically—without soil, using only water, nutrients, and a substrate.
The benefits of eSoil include low energy consumption, safety, and its compatibility with hydroponics, enabling urban agriculture to meet the challenges of a growing population and climate change.
