What is the difference between gravity and pressurized irrigation?
There are two main types of irrigation systems: gravity and pressurized irrigation. Gravity irrigation uses the force of gravity and field borders or furrows to distribute water across a field. Open ditches or pipe systems along with siphon tubes, ditch gates, pipe valves or orifices deliver the water to the field. Pressurized irrigation, on the other hand, delivers water to the field under pressure in lateral, hand-move, and center-pivot pipe systems with attached sprinklers. It may also use drip/trickle tubes and micro-spray systems with drip emitters or micro-spray nozzles to distribute water.
