Self-Watering SMAG-Soil Pulls Moisture From the Air
5th November 2020
Generally speaking, you don’t see a wide variety of crops being grown in arid regions – especially when irrigation isn’t practical and/or affordable. That could be about to change, though, with the development of what’s being described as “self-watering soil.”
Created by engineers from The University of Texas at Austin, the material consists of a 1:3 weight-ratio combination of hydrophilic (water-attracting) hydrogels and natural sandy soil. It’s known as SMAG-soil, with SMAG standing for “super moisture absorbent gels.”
