Drip irrigation systems distribute water through a network of valves, pipes, tubing, and emitters. Depending on how well designed, installed, maintained, and operated it is, a drip irrigation system can be more efficient than other types of irrigation systems, such as surface irrigation or sprinkler irrigation.
Drip irrigation, also known as microirrigation or trickle irrigation, functions as its name suggests. In this system, water is delivered at or near the root zone of plants, one drop at a time. This method can be the most water-efficient method of irrigation, [ 26 ] if managed properly; evaporation and runoff are minimized.
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.
The invention of drip irrigation by Simcha Blass has led to a large expansion of agriculture in arid regions, and in many places drip irrigation is the de facto irrigation technique utilized. Studies have consistently shown large water use reduction with drip irrigation or fertigation , with one study returning an 80% decrease in water use and ...
Drip irrigation – Less wasteful than sprinklers. It is not only more efficient for fertilizer usage, but can also be for maximizing nutrient uptake in plants like cotton. [3] Drip irrigation using fertigation can also increase yield and quality of fruit and flowers, especially in subsurface drip systems rather than above surface drip tape. [4]
Farmers in the valley say the shrinking water levels and competing interests over river usage will badly impact the nation’s food supply. "A lot of people say that the Colorado River and the ...
