An atmospheric water irrigation system based on super moisture absorbent gels (SMAG) is developed for sustainable agriculture technology. The SMAG-soil can harvest water from the air and provide water to the plants upon solar heating regardless of the local accessibility to liquid water resources. As a benefit of this solar-powered atmospheric water irrigation system, agriculture can become geographically and hydrologically independent. Thus, crop planting in underdeveloped and drought areas can be liberated from the long-distance water and power supplies.
