The present invention provides a system and method for maintaining desired pressure levels in an irrigation system when the flow rate available to the irrigation system is reduced below the system's required flow rate. According to a first preferred embodiment, the present invention teaches a method which includes the steps of: receiving and storing irrigation system information including sprinkler specifications, flow rates and pressure requirements; receiving and storing an irrigation plan to be executed including the target amount of an applicant to be applied to a target area; determining an available flow rate to the irrigation system; determining a required flow rate of the irrigation machine; comparing the available flow rate to the required flow rate to determine whether the available flow is sufficient for the system based on the sprinkler specifications; adjusting the pulse rate of the sprinklers to reduce the require flow rate to at least the available flow rate; and calculating and selecting a lower ground speed required to apply the target amount of applicant to the target area based on the selected pulse rate for the sprinklers.

A plant grow rack that includes a base portion having semi-circular bracket and a plurality of stakes and support hooks attached thereto and is adapted to be placed around an existing plant, be pushed into the ground, and hold a semi-circular water supply line above the ground and around the plant to thereby water said plant.

The invention relates to a device for conducting water in a ground surface, comprising a nonwoven layer introduced into the ground (6), which nonwoven layer has at least one conduit strand (4) provided with passage openings (5) for conducting water. In order to create advantageous construction conditions, it is proposed that the nonwoven layer forms a grid (1) made of intersecting arrays of grid strands and comprises a nonwoven web (3) extending along the conduit strand (4), and that at least one array of grid strands formed of nonwoven strips (2) adjoins the nonwoven web (3).

A sprinkler apparatus, a flow rate control valve assembly, and a sprinkler irrigation system for providing an even distribution of water across an asymmetrically shaped water receiving area. The sprinkler apparatus comprises a pop-up sprinkler head with a base housing for confiningly receiving a pressurized water flow that actuates a nozzle housing slidingly and rotationally cooperating with the base housing to pop-up into an operating position for discharge of water through at least one pair of nozzle assemblies. The pair of nozzle assemblies comprise an upper nozzle assembly and a lower nozzle assembly near the top end of the nozzle housing. The upper nozzle assembly controllably projects the pressurized water flow for a precisely set distance, while the lower nozzle assembly comprises a vertical slit-shaped aperture through which water is discharged in a curtain effect. Together, the pair of nozzle assemblies achieve a substantially uniform elliptical linear spray pattern with a bias to outermost end. A flow rate control valve assembly is further described and comprises a flow control valve assembly that can be fluidly coupled to a pop-up sprinkler head to controllably supply the pressurized water flow, the flow control valve assembly comprising a water inlet fluidly coupled to a water supply and a water outlet fluidly coupled to the pop-up sprinkler head, the water outlet cooperatively engaging with a rotary disc valve having a tapered passage wherein sliding rotation of the rotary disc valve incrementally adjusts the valve between an opened position and a closed position to control the pressurized water flow through the water outlet.
