An oscillating sprinkler assembly includes a body including an inlet configured for connection to a water supply; a riser movably mounted in the body and movable from a retracted position to an extended position; a nozzle housing rotatably mounted on a top of the riser; a pressure regulating assembly mounted at an inlet of the riser and operable to control pressure of water into the riser based on an downstream pressure; a water turbine mounted downstream of the pressure regulating assembly such that water from the pressure regulating assembly passes through the water turbine to rotated one or more blades thereof, wherein the one or more blades are operatively connected to the nozzle housing and drive rotation of the nozzle housing; and a bypass valve, provided between the pressure regulating assembly and the water turbine and operable to control water flow to the water turbine.

Embodiments of the present invention are directed to methods and systems for treating irrigation water by introducing a propagating electromagnetic field into the irrigation water as it flows through an irrigation system. The treatments described herein may have a variety of beneficial effects when applied to hydrophobic soils, including a significant increase in the percentage of the water that is maintained in the root zone of a given crop as plant-available water and the essential mineral, e.g. calcium and/or magnesium, uptake of that crop. The treatments described herein may also have beneficial effects when applied to hydrophilic soils, and particularly high salinity, hydrophilic soils, including a reduction in the soil salinity, including the amount of chlorates, within a root zone of a crop.

The present invention belongs to the technical field of landscape garden engineering, and specifically discloses a salt-isolated rain garden structure. The salt-isolated rain garden structure includes a depression surrounded by side slopes, where a 10 cm thick drainage layer, a 10-30 cm thick filler layer, a 5 cm thick transition layer, a 20-30 cm thick planting layer, a 0.2-0.5 cm thick mulch layer and a 15-20 cm thick ponding layer are stacked in order from the bottom of the depression to up; a salt barrier is disposed between the planting layer and the transition layer and/or between the drainage layer and a saline layer; a vertical overflow pipe and a horizontal drainage pipe are disposed at the bottom of the depression; the overflow pipe and drainage pipe are connected; the salt barrier is filled with river sand, zeolite or ceramsite and is 10-20 cm in thickness.

A portable sprinkler device is disclosed herein. The portable sprinkler device is configured to deliver a personalized combination of water, weed killer, lawn fertilizer, and insect control serum. The device may include a wireless control unit capable of communicating with a user interface. The wireless control unit may be configured as a Bluetooth-ready device. The user interface may further include a base station or other portable electronic device. The device is useful for delivering a combined liquid-based lawn treatment solution in a user-friendly manner.

A liquid cleaning and watering system for living plants rests on a surface covered by a non-porous material. A plate layer covering the non-porous layer has two or more layers, each layer having runners arranged in a grid. The grid of each successive layer is offset at an angle with respect to the grid of a previous layer. An upper layer covers the plate layer and has a plurality of holes for the passage of liquids into the liquid cleaning system. As the living plants are watered or cleaned, excess liquids containing water and oils that were excreted by the living plants enter the liquid cleaning system through the holes, the liquid traverses the grid layers, flowing towards a drain. Contaminants within the liquid collect within the grid of the layers of the plate layer for later disposal.
