Abstract:
1. A system for efficiently delivering an aqueous solution to plants comprising: a hydrophobic tube at least a portion of a surface of which is coated with a substantially water-insoluble hydrophilic polymer, the portion at least along a distal portion, the distal portion positionable adjacent a root system of a plant, the hydrophilic means having a lumen therethrough for channeling an aqueous solution from an inlet to the distal portion, the hydrophilic means further having a wall encompassing the lumen, at least a portion of the wall along the distal portion 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 hydrophilic means inlet.
