Abstract:
1. A system for efficiently delivering water and nutrients to plants comprising: a microporous tubing comprising a hydrophilic polymer, a distal portion of the tubing positionable adjacent a root system of a plant, the tubing having a lumen therethrough for channeling an aqueous solution from an inlet to the distal portion, the tubing having a porosity adapted for permitting a flow of the aqueous solution therethrough when acted upon by a surfactant root exudate; and a reservoir adapted for holding the aqueous solution therein, the reservoir in fluid communication with the tubing inlet, wherein the reservoir comprises: a container having an interior space for holding the aqueous solution therein, the container movable between an expanded state when containing solution and a retracted state when solution has been removed; a filling inlet in fluid communication with the container interior space for adding solution thereto; and a distribution tube in fluid communication with the container interior space and with the tubing inlet, for providing solution to the hydrophilic means lumen.
