  • Patent number: 9848543
    Abstract: A method for subsurface irrigation having the steps of; providing one or more hydrophobic porous uncoated tubes having a hydro head (HH), locating the tubes with at least a portion of their length within the rhizosphere of plants to be irrigated, and passing an aqueous irrigation liquid into the tubes during the growth phase of the plants to be irrigated at an applied pressure at or below HH. The tubes may be located in the proximity of seeds which become the plants to be irrigated following their germination. In this embodiment, aqueous irrigation fluid is passed into the tubes during a germination phase of the seeds at an applied pressure that is at least 10% higher than the applied pressure during the growth phase of the plants.
