"Self-watering soil could transform farming" Topic

"The team's atmospheric water irrigation system, details of which have been published in the journal ACS Materials Letters, uses super moisture-absorbent gels to capture water from the air. When the soil is heated to a certain temperature, the gels release the water, making it available to plants. When the soil distributes water, some of it goes back into the air, increasing humidity and making it easier to continue the harvesting cycle.

"Enabling free-standing agriculture in areas where it's hard to build up irrigation and power systems is crucial to liberating crop farming from the complex water supply chain as resources become increasingly scarce," said Guihua Yu, associate professor of materials science in the Walker Department of Mechanical Engineering…"
