The present invention is a system for treating land, either to reclaim or optimize the land. Embedded subsurface pipes deliver water to the land. The water may be loaded with soil-treating additives. As water streams from the pipes, it treats the land before passing into a drainage ditch around the periphery of the land. The water is removed from the ditch and recycled, removing contaminants (in reclamation operations) or adding more additives (in optimization operations), before returning to the pipes for another round of treatment, if necessary.

A system and method employ a pair of conventional water barrier panels connected to my tree-watering device. The tree-watering device and panels have interactive connectors configured to enable connection together. In a vertical orientation the barrier panels are sunk into the ground in which a tree is planted and below the ground surface, positioning the panels nearby each other to at least partially encompass roots of the tree. In a vertical orientation sinking the tree-watering device into the ground. A top end of my device is at or near the ground surface. A lower portion of my device has one or more openings therein facing the tree and being at least 12 inches below the ground surface. Lastly, introducing pressurized water into the interior of the tubular member so waters flows out the sidewall of the tubular member through the openings therein towards the tree.

A clog resistant in-line irrigation emitter or nozzle assembly having an emitter structure designed to be inserted into an extruded tube as part of a drip irrigation system. The nozzle assemblies take the high pressure and flow inside the tube and produce a desired flowrate (selectable depending on the requirements of the environment). The emitter of the present disclosure has a higher efficiency than traditional pivot or sprinkler systems or known emitter devices. The emitters not only provide the appropriate pressure attenuation; they resist clogging from the grit and debris in available ground water. The clog resistant in-line irrigation emitter gives a greater pressure attenuation for its physical dimensions than comparable devices and provides an optimal design of a pressure compensating device that improves diaphragm performance. The instant disclosure does allow for the pressure compensation device to be used with various embodiments of a pressure reducing components.

A subterranean irrigation system (100) has a plurality of fluid conduit (130) for applying a liquid from a source to an area of ground, to which said liquid is to applied while avoiding interference with the above-ground use of such area, wherein the fluid conduits (130) are connected (140; 500) relative to one another and wherein the plurality of fluid conduits (130) comprise a plurality of outlets to effect the distribution of the liquid to the ground area, wherein the plurality of outlets (600;621, 622, 623; 800; 821, 822, 823) are provided at an underside (602, 802) of a nose-shaped spout attachment (600, 800), wherein the spout attachment (600; 800) is attached at the side in the upper half of the fluid conduit (130; 230; 720) and wherein the underside (602; 802) comprises a rounded surface starting tangentially from the outer diameter of the fluid conduit (130; 230; 720) and ends in the nose-shaped free end of the spout attachment (600; 800).

A self-feeding watering device comprises a water storage unit, a regulating component and a long nozzle cover, and a water guide string extending out of the water storage unit. The regulating component is engaged to the water storage unit. The cover comprises a top cover for connecting with an external container and a long nozzle tube penetrating through the top cover and communicating with the top cover. The long nozzle tube further penetrates through the regulating component and extends towards a bottom of the water storage unit. The string is partially placed at the bottom of the water storage unit, and partially extends out of the water storage unit. The string allow water to penetrate into outside of the unit, and further guiding the water into the soil for automatic irrigation. The device has a compact structural body, can adjust a watering flow rate by a simplified means.

Aeration and drying of subsurface soils with a subsurface irrigation system. An air inlet and bypass pressure regulator allow pressurized gas to be introduced into a zone of the system to aerate and dry a field. Pressurized gas or aerosolized agrochemicals are delivered through emitters integrated into the driplines within the system. Emitters integrated into the driplines allow aeration and drying of subsurface soils during times of season when high amounts of precipitation or localized flooding interfere with the systems use for irrigation.
