E-Soil

Researchers have developed a new electronics soil that was found to increase the growth of barley seedlings by 50%.

It is a novel method of soilless gardening or hydroponics using an electrically conductive growing medium.

In hydroponic environments, eSoil is a low-power bioelectronics growth substrate that can electrically stimulate the root system and growth environment of plants.
This novel substrate is not only environmentally friendly, but also offers a low energy, safe alternative to previous methods that required high voltage and non-biodegradable materials.

eSoil is being derived from cellulose and a conductive polymer called PEDOT.

Working - When the roots of barley seedlings were electrically stimulated for 15 days, they showed a 50% increase in growth using eSoil.
In hydroponics, plants are grown without soil, requiring only water, nutrients and a substrate, something for their roots to attach to.

Hydroponics is the technique of growing plants using a water-based nutrient solution rather than soil, and can include an aggregate substrate, or growing media, such as vermiculite, coconut coir, or perlite.

This closed system allows water to be recirculated, ensuring that each seedling receives exactly the nutrients it needs.
As a result, very little water is used and all the nutrients remain in the system, something that is not possible with conventional farming.
