Center pivot on agricultural production robot

摘要

Travelers looking out airplane windows while flying across the United States may wonder what creates those giant green circles so visible from 30,000 feet. The circles are crops irrigated with a self-propelled sprinkler irrigation system that rotatesaround a central point commonly called a "center pivot system" or "center pivot." "Without the center pivot, there would be very little irrigation in North Dakota," said Tom Scherer, North Dakota State University Extension Service agricultural engineer."The economic impact of irrigated high-value crops, such as potatoes and other vegetables, would not exist."
