Abstract:
1. A system for efficiently delivering a solution to a plant comprising: a microporous solution-channeling device comprising a hydrophilic material at least at a delivery portion thereof, the solution-channeling device positionable adjacent a root system of a plant, the solution-channeling device having a lumen for channeling a solution therethrough from an inlet to the delivery portion, the solution-channeling device further having a porosity at least at the delivery portion adapted for permitting a flow of a solution therethrough when acted upon by at least one of a surfactant root exudate and negative root pressure; and a pressure-regulating device positionable in fluid communication at an upstream portion with a source of the solution and at a downstream portion with the inlet, for providing at least a minimum pressure value to permit solution to flow through the solution-channeling device and at most a maximum pressure value above which solution would flow through the solution-channeling device even in an absence of the at least one of the surfactant root exudate and negative root pressure.
