Abstract

In 1989 there were 4 million ha of cropland under center pivot irrigation in the 17 western states
(irrigation Journal 1990). The largest areas under center pivot are in the High Plains with soils
ranging from sands to clay loams, and the Pacific Northwest with predominately silt loam soils. Most
center pivot systems in the semi-arid areas are designed with gross capacities near the peak
seasonal evapotranspiration rate, or approximately 10 mm/d. The length of a typical center pivot
lateral ls about 400 m, which evolved from standard field sizes in the western U. S. Application rates
are highest near the outer end of the lateral and are determined by the system capacity, length of
lateral, and the width of the water application pattern.
