In 1952 Frank Zybach patented what would become
the center pivot irrigation system and revolutionized
irrigation and thus agriculture all over the world.
"The July 22, 1952 patent...marked the birth of a revolution in irrigation technology."
David Howe, The Groundwater Foundation
"...the center pivot, in less than fifty years, has
revolutionized irrigation as a part of agriculture production."
