Abstract
An irrigation system for a field, wherein a circular central portion of the field is irrigated by a center pivot irrigation machine, comprising a buried primary water line which extends from a source of water to the vicinity of the field area to be irrigated. At least one, and normally several, header water lines are in fluid communication with the primary water line and extend therefrom with a three-way pulse valve being imposed in each of the header water lines. A plurality of distribution water lines are in fluid communication with each of the header water lines and extend therefrom downstream of the pulse valve. A plurality of spaced-apart, in-line pulse emitter valves are imposed in each of the water distribution lines and have a water discharge orifice associated therewith for discharging water outwardly from the water distribution line to the area immediately adjacent thereto.
