A system, device and method for delivering CO2 or other gases to plants in fields, orchards, vineyards and the like. A stake with a windbreak structure and gaseous emitters on the upwind side creates a leeward wind eddy surrounding a plant, such as an orchards sapling. This establishes and maintains a gaseous microclimate beneficial to the plant. The device delivers CO.sub.2 gas to a plant in an agricultural field, orchard, grove, orchard of the like. The device includes an elongated base adapted to be adjustably placed on the ground a predetermined distance from the plant, upwind of the plant. A wind foil is adjustably connected to the base along its elongated length. The wind foil has a curvilinear geometry with a first face having a generally convex configuration, and a second face having a generally concave configuration. An emitter assembly is disposed on the second face of the wind foil. A gas supply conduit is communicatively connected to the emitter and adapted to be connected to a gas supply. A system including multiple devices and a method of making and using the device and system are also disclosed.

A fluid delivery system utilizes Bernoulli pressure differentials and kinetic forces is provided. The system includes a pressurized channel in fluid communication with a flexible pressurized line for translating pressurized fluids to a mixing chamber. The mixing chamber is also in fluid communication with a source channel receiving fluids from a flexible source line. The mixing chamber is configured for entraining the source fluids with the pressurized fluids 26 using Bernoulli principles. Kinetic valves may be used in conjunction with, or in lieu of, the Bernoulli siphoning.

Example implementations of a synthetic turf system comprise a turf tray and a turf element. The turf tray is rigid and planar, and has a lattice structure extending within the lateral perimeter. The turf element includes a backing portion and a blade portion. The blade portion is defined by a plurality of blades of artificial grass affixed to the backing portion, the backing portion is placed secured engagement with the upper side by way of, for example, adhesive or screws. The turf trays may include perimeter and auxiliary adhesive tracks, and an array of screw retention bosses. The system may include a sprinkler assembly mountable in the turf trays for washing down the turf elements. The sprinkler assembly may include mounting flanges configurable to accommodate mounting of various sprinklers. The system may include height-adjustable pedestals or joists to support the turf trays at a distance above the local horizonal surface.

An irrigation spraying device includes: a tee joint, a ground picket, a spraying head and two quick connectors. The spraying head is disposed at a top portion of the tee joint; the two quick connectors are disposed on two sides of the tee joint respectively; and a top portion of the ground picket is provided with an engaging portion, which includes two clips matched with two ends of the tee joint respectively. The device can achieve spray irrigation through hanging, can adapt to various irrigation scenes, improves its adaptability, and is simple in structure, convenient to operate, and suitable for popularization and application. A setting of the clips enables a rotation of the tee joint to realize angle adjustment of the spraying head, thereby adjusting the angle of the spraying head during ground irrigation, further improving the adaptability of the device to meet needs of various irrigation scenes.
