The Center Pivot - The First Irrigation Machine
SAE Technical Paper Series, 1979<div class="htmlview paragraph">The commercial development of the center pivot irrigation machine has brought the technology of machine design into an area formerly dominated by hydraulics and hydrology. The major attributes of these systems--accommodations to sandy soils and rolling terrain, efficiency in application of water, automation and ...

Water and energy conservation using irrigation scheduling with center-pivot irrigation systems
Agricultural Water Management, 1992Abstract An extension project covering portions of two counties in north central Nebraska, USA, demonstrated that irrigation scheduling and pumping plant adjustment practices reduced energy costs for center-pivot irrigated corn ( Zea mays L.). Data were collected for 51 center-pivot systems; 19 employed irrigation scheduling techniques (Schedule ...

Energy Savings and Irrigation Performance of a Modified Center Pivot Irrigation System
Applied Engineering in Agriculture, 1994The demand for power by a center pivot irrigation system changes with the operating point of the system-pump curve during the opening and closing of the end gun sprinkler. The purpose of this research was to determine the possible energy savings of a “modified” center pivot irrigation system in which the operating point of the system-pump curve is held

A Renewable Solution Approach for Center Pivot Irrigation System
2018 IEEE Rural Electric Power Conference (REPC), 2018In this present study a hybrid renewable energy system is proposed to optimize the load demand for Center Pivot Irrigation System for remote cultivation areas in Lubbock, Texas. The energy resources included in the study are solar photovoltaic and wind energy. For the ease of study, a 120-acre cultivable land area is considered as model. Simulation and

Environmental Benefits and Concerns of Center-Pivot Irrigation
2017Center-pivot irrigation systems started in the United States in the mid-20th century as an irrigation method which surpassed the traditional surface irrigation methods. At that time, they had the potential to bring about higher irrigation efficiencies with less water consumption although their requirements in energy were higher too.

Economic Feasibility of Converting Center Pivot Irrigation to Subsurface Drip Irrigation
2016Advancements in irrigation technology have increased water use efficiency. However, producers can be reluctant to convert to a more efficient irrigation system when the initial investment costs are high. This study examines the economic feasibility of replacing low energy precision application (LEPA) center pivot sprinkler irrigation with subsurface ...

Characterizing center pivot irrigation with fixed spray plate sprinklers
Science China Technological Sciences, 2010An indoor experiment with a fixed spray plate sprinkler (FSPS) of 36-grooved plate D3000 was conducted to evaluate the discharge-pressure relationship, wetted diameter, effective width, and water application rate in this research. In addition, a field experiment with a center pivot system equipped with the same measured FSPS was carried out to ...

Infiltration Model for Center Pivot Irrigation on Bare Soil
2012 Dallas, Texas, July 29 - August 1, 2012, 2012The marked reduction in infiltration rate caused by formation of a soil surface seal due to water droplet impact on bare soil is a well known phenomenon but is rarely considered in infiltration models, especially under center pivot irrigation. The objective of this study was to develop a soil infiltration model for center pivot sprinkler irrigation ...
