How does gravity irrigation work?
Gravity irrigation systems use on-field furrows or basins to advance water across the field surface through gravity-means only. Pressurized systems apply water under pressure through pipes or other tubing directly to crops. Pressurized irrigation includes acres irrigated by sprinkler and micro/drip irrigation systems. Under many field conditions, pressurized irrigation systems are generally more water-use efficient than gravity systems as less water is lost to evaporation, deep percolation and field runoff. Over the last 30 years the conversion of gravity to pressurized irrigation systems has increased. In 1984, 37 percent of all irrigated cropland acres in the western U.S. used pressurized irrigation systems, as compared with 72 percent in 2018.
