What is eSoil?

About eSoil:

• In hydroponic environments, eSoil is a low-power bioelectronic growth substrate that can electrically stimulate the root system and growth environment of plants.
• This novel substrate is not only environmentally friendly, being derived from cellulose and a conductive polymer called PEDOT.
• It offers a low energy, safe alternative to previous methods that required high voltage and non-biodegradable materials.
• It uses low energy and minimises resource consumption.
• Its active material is an organic mixed-ionic electronic conductor.

How does eSoil work?

• When the roots of barley seedlings were electrically stimulated for 15 days, they showed a 50% increase in growth using eSoil.
• This research promotes more effective and sustainable development while increasing the variety of crops that can be grown hydroponically.
• In hydroponics, plants are grown without soil, requiring only water, nutrients and a substrate – something for their roots to attach to.
• This closed system allows water to be recirculated, ensuring that each seedling receives exactly the nutrients it needs.
• As a result, very little wateris used and all the nutrients remain in the system – something that is not possible with conventional farming.
• Benefit: It can help in areas with little arable land and harsh environmental conditions.

Q1:What is an electrical conductor?

It is a substance or material that allows electricity to flow through it. In a conductor, electrical charge carriers, usually electrons or ions, move easily from atom to atom when voltage is applied.
