Abstract: An irrigation system is provided for irrigating a field divided into irrigation zones. The irrigation zones are arranged in columns extending alongside each other. The system has irrigation strips and a control head at an upstream end of each irrigation strip. Each irrigation strip provides irrigation substances to a column of zones. All control heads are located alongside a boundary of the field outside of the irrigation zones. This permits maintenance of the control heads without the need to enter the irrigation zones.

Abstract: A fiber optic beam splitter includes housing, a single first optical fiber and a pair of second optical fibers which meet and abut the single first optical fiber at inside the housing. An optical communication module includes a light-emitting diode (LED); a photodiode; and two such fiber optic beam splitters. In each beam splitter, a tip of a first of the pair of second optical fibers is connected outside of the housing to the LED, and a tip of a second of the pair of second optical fibers is connected outside of the housing to the photodiode; and a tip of the single first optical fiber which is outside of the housing, is in optical communication with an exterior of the module. An optical communication network includes two or more such optical communication modules. An irrigation system configured to support a field of crops includes such an optical communication network.

Abstract: An irrigation column for a drip irrigation system has a fluid conducting line for receiving fluid from a fluid source upstream. The irrigation column further includes a plurality of drip line segments extending alongside the fluid conducting line, a plurality of zone valves located along the fluid conducting line, and a plurality of control tubes extending alongside the fluid conducting line. And each control tube is in fluid communication with a respective one of the zone valves for actuating the zone valve.
