Drip irrigation or trickle irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface.
Micro-irrigation, also called Micro-spray,localized, low-volume, low-flow, or trickle irrigation, is an irrigation method with lower water pressure and flow than a traditional sprinkler system. Low-volume irrigation is used in agriculture for row crops , orchards , and vineyards .
Drip irrigation – a dripper in action. Micro-irrigation, sometimes called localized irrigation, low volume irrigation, or trickle irrigation is a system where water is distributed under low pressure through a piped network, in a pre-determined pattern, and applied as a small discharge to each plant or adjacent to it. Traditional drip ...
The first experimental system of this type was established in 1959. In the early 1960s, Blass developed and patented this method and the new dripper was the first practical surface drip irrigation emitter. During the years 1960 to 1965 Blass developed the drip-irrigation systems and sold them inside Israel and abroad.
Illustration of a pulse drip irrigation system. Magnets hold the valve closed while water comes in through the inlet and drip flow controller to charge the reservoir. When the building pressure finally overcomes the attractive force of the magnets the top set of magnets are forced upward to open the valve.
Surge Irrigation is a variant of furrow irrigation where the water supply is pulsed on and off in planned time periods (e.g. on for 1 hour off for 1½ hour). The wetting and drying cycles reduce infiltration rates resulting in faster advance rates and higher uniformity [ 4 ] than continuous flow.
