Drip emitter for periodic, volumetrically-timed, irrigation and drip irrigation laterals comprising such emitters, wherein the drip emitter implement a water-accumulation chamber as a hydro-mechanical timer and comprises in addition, a first no-drain valve positioned on the downstream side of the irrigation water inlet to the drip emitter, a second valve located on the downstream side of the irrigation water flow path in the drip emitter, and a water drain that connects to the flow of irrigation water from one side of an elastic member in the emitter's water-accumulation chamber to the second valve, in a manner that helps to close it.

This emitter has an emitter main body comprising a first face, a second face disposed on the opposite side from the first face, and a side face connecting the first face and the second face; a water intake unit for taking in irrigation liquid disposed on the first face side; a discharge unit for discharging irrigation liquid disposed on the second face side; a flow path that connects the water intake unit and the discharge unit and allows the irrigation liquid to pass therethrough; and a protrusion disposed on the side face.

This emitter has an emitter body and a pedestal. The emitter body includes: a water intake part for introducing irrigation liquid; a pressure reducing flow passage groove which is for forming a pressure reducing flow passage which communicates with the water intake part and allows the irrigation liquid to flow out while reducing the pressure of the irrigation liquid; an accommodation part which communicates with the pressure reducing flow passage groove and into which the irrigation liquid flows while the pedestal is accommodated therein; and a flexible diaphragm part which approaches the pedestal upon receiving the pressure of the irrigation liquid inside a tube while the pedestal is accommodated in the accommodation part. The pedestal has through-holes for discharging the irrigation liquid that flowed into the accommodation part. The emitter body and the pedestal are connected through a hinge part.

A pressure compensation member, an irrigation drip emitter, drip lines and methods relating to same, are provided for delivering irrigation water from a supply tube to an emitter outlet at a reduced and relatively constant flow rate. The pressure compensation member being suitable for use in conventional emitters or alternate emitters being provided having either a uniform elastomeric emitter body configuration or a poly-material emitter body utilizing an elastomeric pressure compensation member. Various methods are also disclosed herein relating to the pressure compensation member, emitters and/or drip line using such pressure compensating members and/or emitters.

A drip emitter sized for insertion into a liquid supply tube and positioned adjacent to a dripping aperture in the tube comprises an emitter body having a convex side configured to internally and adjacently fit the tube and an opposite flat side comprising a regulator, wherein the convex side comprises an outlet chamber configured to be fluidically connected to the dripping aperture; a membrane covering at least the regulator; a cover provided with a liquid intake having a filter, wherein the cover is configured to envelop the emitter body except of most of said convex side; and a locking mechanism connecting the flat side and an inner surface of the cover that is adjacent to the flat side so as to join the cover to the emitter body, wherein the membrane is retained therebetween.

A discrete flat dripper of the non-pressure regulated type of drippers or of the pressure compensatedflow rate regulated type of drippers, suited for being integrally installed within a hose, that comprises a body component whose configuration is essentially rectangular, wherein on its one side that is suited to being affixed to an internal wall of the hose, formed with an exit pool that it is elongated in its dimensions and substantially extends along the entire length of the body component, and with a flow passage circumferentially surrounding a substantial part of the elongated exit pool, and an integral dripper line wherein there are integrated at least one of such discrete flat dripper.

A pocket structure for receiving containerized plants is sloped and hung from a wire of a wire basket. The pocket structure includes hooks, an irrigation fitting and corresponding drip channel to transmit water toward the rear of the pocket, and slots in the walls. The mesh units include braces and are sized for shipping. An earth wall is formed of the mesh units and pockets, and includes irrigation tubing. The components may be formed into a palletized kit.

The present invention relates generally to a system and method for detecting and adjusting the position of an irrigation span. More particularly, the present invention provides a system and method for detecting and removing deflection stresses from irrigation spans caused by corner arm positioning.

The present invention relates to a tree watering apparatus that can be used to irrigate the base of a tree and to protect the roots thereof. The present invention comprises a semi-circular ring having a bottom half that serves as a root barrier and a top half that serves as a barrier to retain water around a tree while the water percolates to the root system of the tree. A distribution tubing is attached to a water supply and directs water around a tree which is then retained on the ground around the tree by the top half of the present invention while it percolates into the ground. Water that percolates into the ground is then directed to the root system of the tree by the bottom half of the present invention that is buried.

A modular hydroponic tower array fixture system for the growth of organisms such as plants and fungi on arrays of hydroponic towers, allowing for the insertion and removal of individual towers from the array, is provided. Methods for the production of organisms such as plants and fungi using a modular hydroponic tower array fixture system are also provided herein.
