Source- This post is based on the article “What is eSoil and how does it work? Here’s everything you need to know about this electrically conductive substrate” published in “Hindustan Times” on 26th December 2023.
Why in the News?
A recent study by Linköping University’s on ‘electronic soil’ (eSoil) and hydroponics (soil-less cultivation) presents hope for sustainable urban agriculture and food security.
What is eSoil?
1) eSoil serves as a low-power bioelectronic growth substrate capable of electrically stimulating both the root system and the growth environment of plants.
2) This innovative substrate has been derived from cellulose and the conductive polymer PEDOT.
3) Its active material is an organic mixed-ionic electronic conductor.
4) Advantages:
a. It is environmentally friendly.
b. It provides a safe alternative to previous methods that relied on high voltage and non-biodegradable materials.
c. eSoil employs minimal energy and reduces resource consumption.
What is the Significance of eSoil?
1) The finding holds significance for hydroponics cultivation and will promote its associated benefits such as vertical farming.
2) It will ensure the viability of urban agriculture and ensure food security.
3) It’s low energy consumption offers a sustainable solution for growing food needs.
