Patent abstract
A system and method for efficiently delivering an aqueous solution to plants includes a hydrophilic delivery device, for example, tubing, that has a distal portion positionable adjacent a root system of a plant and a lumen for channeling an aqueous solution from an inlet to the distal portion. At least a portion of the device's wall along the distal portion has a porosity adapted for permitting a flow of the aqueous solution therethrough when acted upon by a surfactant root exudate and/or negative pressure generated by the roots due to water stress. A reservoir is adapted for holding the aqueous solution therein and is situated in fluid communication with the hydrophilic device's inlet.
