Anything that humans use to can bring water into the soil is referred to as irrigation. It can be a pipe to water plants, or more complex, like canals designed to provide moisture to a desert.
If rainfall is not enough to provide water for crop, irrigation may be applied. It is estimated that 50% of the world’s population is irrigated. Irrigation has been used since the beginning of time.
Flood (furrow) or drip and spray are some of the most common types of water filtration.
Flood irrigation refers to when irrigation water is introduced into fields in order to let it flow over all the soil. Drip irrigation is when water is sent across a pipe that has holes. It uses 25 percent lesser water than flooding irrigation. Spray irrigation is the process of pumping water through pipes and at high pressure via an sprayer. It requires electricity. The process also consumes lots of water. As a result, spray irrigation isn’t nearly as popular as other methods. Overall, it uses a lot of water.
