A hand tool for inserting a large variety of connector components into narrow plastic irrigation piping is disclosed. This tool is an improved and progressive development of my previous Israeli patent no: 152089 in that it is designed to work with a large variety of connector components and is designed to accommodate both sizes of narrow spaghetti piping, whereas the previous patent could accommodate only a single size of narrow piping. The tool as shown in FIG. 2 has a body onto which all the elements are connected and the body is configured to sit comfortably in the palm of the hand. When pressing down on the handle, the grips secure the narrow piping and cause a connector component, deployed in appropriate recess provided in the tool to be easily inserted into the narrow piping.

Methods and systems control an irrigation system that includes an irrigation controller, a valve actuator, and at least one irrigation sensor connected by a communication circuit. A sensor charging pulse having a temporal duration less than a solenoid actuation time threshold for a solenoid is provided over the communication circuit. The sensor charging pulse charges a charge storage device in at least one irrigation sensor. A series of addressing pulses is also generated over the communication circuit, which indicate a device identifier of at least one irrigation sensor. The series of addressing pulses activate at least one irrigation sensor having the device identifier indicated by the series of addressing pulses such that the activated irrigation sensor provides a sensor signal indicative of an irrigation condition to the irrigation controller via the communication network.

The invention is a centralized server-based system containing a database with relevant information regarding features, parameters, and characteristics of a particular irrigation system, which utilizes proprietary irrigation software to control a plurality of field modules, at one or more remote locations, via a network bridge adapter.

The steps of the irrigation method include: flowing a stream of water having input and output and intermediate location; interposing a feeding device into the stream of water at the intermediate location, the feeding device having input and output ends; inserting a quantity of nutrient fertilizer into the feeding device; converting the nutrient fertilizer from the viscous state to the less viscous state through the flow of water through the feeding device; and intermixing the viscous nutrient fertilizer with the water entering the feeding device whereby the water leaving the device to plants and soil will include a fertilizer.

An irrigation device comprising a moisture responsive barrier is provided. At least a portion of the barrier has perforations, at least some of the perforations are associated with a water swellable material. The perforations are configured to open as the water swellable material loses moisture and dries out and are configured to close as said water swellable material is exposed to and absorbs water, such as during a watering step. According to another aspect the irrigation method includes the steps of positioning a perforated barrier between a source of irrigation water and an area to be irrigated, wherein the perforations are associated with a water swellable material; exposing the water swellable material to water to cause the water swellable material to swell to close the perforations; and permitting the water swellable material to dry, to open the perforations, whereby the opening and closing of the perforations regulates the amount of irrigation water being applied across the barrier in the irrigation method.

Some embodiments provide irrigation valve control apparatuses comprising: a solenoid configured to cooperate with a plunger; an input stimulus source coupled with the solenoid and configured to apply an input stimulus while a plunger drive signal is not being applied and that is sufficiently small to not cause the plunger to move; sampling circuitry configured to measure one or more voltage measurements corresponding to one or more voltages across the solenoid, wherein the one or more voltage measurements are dependent upon the current position of the plunger relative to the solenoid; and control circuitry cooperated with the sampling circuitry to receive the one or more voltage measurements from the sampling circuitry, wherein the control circuitry is configured to determine whether the plunger is in one of the open and closed positions based on the one or more voltage measurements.

A rover includes a base having wheels and a propulsion system coupled to the wheels to propel the rover around a field. A tower is coupled to the base and extends over the base. Sensors are set on the tower and the base and are configured to sense environmental conditions around the rover at different elevations. A computing system includes a processor and memory. The memory is configured to receive measured data from the sensors and determine an amount and manner of water to be dispensed on plant life in the field.

(California Court of Appeal) - Held that local water districts were not entitled to be reimbursed by the state for the cost of complying with unfunded state mandates to improve water service. The water districts argued that reimbursement was necessary because the passage of Proposition 218 had limited their authority to levy fees. Disagreeing, the California Third Appellate District concluded that their authority to levy fees had not changed. The panel affirmed the trial court.

(California Court of Appeal) - In a writ proceeding to challenge the trial court's conclusion that plaintiff was not a 'municipal corporation' for purpose of Public Utilities Code section 10251, which authorizes municipal corporations to recover all damages from any person who injures any facility or equipment of the municipal corporation through want of care, the petition is denied where the term 'municipal corporation' used in section 10251 does not include irrigation districts.

(United States Ninth Circuit) - Granted a petition for review of a Federal Energy Regulatory Commission decision. Two irrigation districts contended that FERC should not have denied their complaint alleging that an electric utility company breached certain agreements with them. Concluding that FERC's orders were arbitrary and capricious, the Ninth Circuit granted the petition for review.

The amount of farmland around the world that will need to be irrigated in order to feed an estimated global population of 9 billion people by 2050 could be up to several billion acres, far higher than scientists currently project, according to new research. The result would be a far greater strain on aquifers, as well as the likely expansion of agriculture into natural ecosystems as farmers search for water.
