The Suchirr SmartR irrigation system uses gravity flow without electricity to distribute water through a modular system of 500 feeder units connected to a feed tank. The simple and low-cost system replaces emitters with patented subsoil dribblers that feed water underground to plant roots, providing fully automatic irrigation without pumps or filters. Individual feeder units store measured amounts of water near each plant to transfer water via subsoil dribblers over 2-8 hours as needed.
