Advances in Surface Irrigation

Ten years ago about 81 percent of the irrigated land in the United States was surface irrigated. Surface irrigated area has increased gradually, but sprinkler irrigated area has increased faster so as to gain about 1 percent of the total area each year. Of all irrigated land in 1975, surface irrigated areas comprised about 75 percent; in 1979, only 68 percent.
