  • Irrigation system and method for controlling liquid flow in adjacent field zones
    Patent number: 11337384
    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.

  • Irrigation system and method having control heads outside of a matrix of irrigation zones
    Patent number: 10849286
    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.

    Publication number: 20180359963
    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.
