Ralph Parshall's venturi flume is in use world wide.		Variable Chemical Application Cooperation with industry partners has resulted in a pivot attached spray system capable of variable chemical application.
	Irrigation Management Center pivot irrigation scheduling programs use weather data to recommend time and amount of irrigation.		Weed Models Use of bioeconomic weed models reduced herbicide use by 6% and increased profit by $11.60 per acre.
	Remote Sensing Crop growth stage and need for nitrogen can be detected in near real time.		Water Quality Water management studies addressed problems from animal waste control to agriculture salinity.
	Surface Irrigation Automation Automatic controls reduced the labor required to change irrigation sets.		Pivot Hydraulics Equations for expressing the uniformity of center pivots are incorporated into international standards.
	Crop Water Use Early evaporation tank studies evolved into evapotranspiration equations and a state wide weather station network.
