This form of irrigation provides water efficiently. It works in a pressurized form similar to natural rainfall. Spray heads at the terminals distribute the water over the entire soil surface. It is then separated through sprinklers so that it splits up into tiny water drops that fall to the ground. Under sprinkler irrigation, water flow passes around through a system of pipes mainly by pumping. Possible damage of system components due to animals, etc.,. Saving in labour and field preparation cost. Easy method of fertigation and chemigation. The water flows through emitters moves with no barrier at the desired pace. The emitters can be placed either on the ground or also planted deep in the soil. These emitters optimize and distribute the water pressure from the water source using vents, twisters, and convoluted or long flow paths, which allows only a limited amount of water to pass through. In drip irrigation system, emitters directly deliver water to the plant root into the soil. It is the most widely form of Micro Irrigation System. Drip Irrigation system is also known as Trickle Irrigation. For our purpose, however, we will restrict our discussion to drip irrigation and sprinkler irrigation that are important for UPSC exam. They are Drip irrigation, Sprinkler irrigation Spray irrigation, Subsurface irrigation, and Bubbler irrigation. There are majorly 5 types of micro irrigation system. Micro-irrigation system has become popular these days for its low cost and water-efficiency. In, this method water is irrigated through drippers, sprinklers, foggers and by other emitters on surface or subsurface of the land. Micro-irrigation system is a modern method of irrigation. 
Micro irrigation topic is very important for UPSC exam and the aspirants must understand the micro irrigation topic comprehensively.
We will also discuss the types of micro irrigation like drip irrigation and sprinkler irrigation. In this article, we will discuss about micro irrigation is also called pressurized irrigation. In the last article, we have discussed about irrigation and types of surface irrigation.
