A method and system for use therein for providing O.sub.2 and H.sub.2 gases directly to the soil proximal to the roots of plants via electrolysis is described. The method employs at least one electrolyzer disposed adjacent to, or inline with, the irrigation waterline of the plant grow operation to facilitate the introduction of the gases to the soil. A power source is used to provide the electrolytic conversion, and gases remain in a micro-bubbled form to flow through the waterline more easily to the plants where they are needed the most. A venturi is used to channel the dissolved gases in the waterline from the electrolyzer in embodiments having an external HyGrO unit. The inline embodiment electrolyzes the water without need of a venturi to reintroduce the gases to the waterline.

A subsurface drip irrigation (SDI) pipe including a polymer water conduit with drippers spaced along a length of its wall and one or more essential oils (EO) adsorbed to a nanoclay (NC) /polymer structure so that EO is delivered to soil surrounding the SDI pipe.

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.

Embodiments are directed to a fluid-emission device. An example fluid-emission device includes a tubular body, a fluid-source coupler, and a tip member disposed opposite the tubular body from the fluid-source coupler. A fluid-transmission lumen in the tubular body fluidly couples the tip member to the fluid-source coupler. The tip member includes a plate having a plurality of fluid-emission lumens that fluidly couple the fluid-transmission lumen to an environment outside the tubular body. The tip member includes a spearhead disposed opposite the plate from the fluid-transmission lumen. The tip member has a spacer disposed between the plate and the spearhead to separate the spearhead from the fluid-emission lumens. The fluid-emission device can be used by inserting the tip member into material and delivering fluid to a target, such as delivering water or fertilizer to plant roots or the like.

The disclosure includes various embodiments of an irrigation mat. In some embodiments, the mat is generally installed so that plants meet the layer of moisture formed by a nonwoven textile web in a relatively short time due to growth of roots. Some embodiments include a web where the roots of plants can grow into the web and thus those plants can be supplied with moisture.

A drip emitter is provided for delivering irrigation water from a supply tube to an emitter outlet at a reduced and relatively constant flow rate. Water enters the emitter through a first inlet and proceeds into a first chamber. When the water pressure is above a predetermined level, a one-directional valve opens to allow fluid flow past the first chamber, through a tortuous path flow channel, and through an emitter outlet. A second inlet is used to compensate for water pressure fluctuations in the supply tube to maintain output flow at a relatively constant rate. Water enters the second inlet and presses a flexible diaphragm toward a water metering surface to provide pressure-dependent control of the output flow. A copper member is mounted to the emitter over the emitter outlet to prevent plant root intrusion into the emitter outlet.
