This paper describes a method of irrigation called measured irrigation (MI). MI is a gravity-feed irrigation system that directly controls the volume of water emitted from each emitter nozzle in each sector during the irrigation event without the need to control the flow rate or the duration of the irrigation event. Three implementations of MI are described: unpowered single-sector MI, solar-powered single-sector MI and solar-powered multi-sector MI. For solar-powered MI, the irrigation frequency is proportional to the evaporation rate minus the precipitation rate. MI does not require access to electricity grid power or to an urban water supply. Trials compare the accuracy and uniformity of MI with pressure-compensating drip irrigation products.
