Ec88-729 Irrigation Pumping Plant Alternatives, Richard T. Clark, Norman L. Klocke

University of Nebraska-Lincoln Extension: Historical Materials

Irrigation pumping costs depend on the requirements of the individual pumping plant. Energy use is the major component of pump operating costs. Pumping efficiency, pumping lift, water pressure and the amount of water delivered all influence the energy required to operate the pumping plant.

This extension circular contains information for irrigators on how to use a computerized spreadsheet developed in 1988 to calculate irrigation pumping costs and savings.

G88-873 Growing Shrubs From Seed, Richard J. Lodes, Mike Kuhns

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide is about gathering and growing seeds for shrubs.

Growing shrubs from seed is educational and fun. Many shrub species are not available commercially, so gathering seed and growing your own plants may be the only way to get them. Interesting or unusual shrubs from a neighbor's yard or from the wild can be propagated from seed. Shrubs started from seed also may be less expensive than commercially produced seedlings.

G88-888 Flow Control Devices For Center Pivot Irrigation Systems, William L. Kranz

University of Nebraska-Lincoln Extension: Historical Materials

Several factors contribute to the need for sprinkler flow rate regulators. This NebGuide discusses them.

Many center pivot irrigation systems operate on undulating terrain. Systems operated on undulating terrain experience large pressure differences in the pivot pipeline. Since water distributed by each sprinkler is determined by the pressure in the pipeline, water applied by these systems can be non-uniform.

Pressure regulating devices that equalize the flow of water from individual sprinklers have become more common since uniform water application may save water and increase overall crop production. When installing a sprinkler package on a new system or replacing sprinklers on …
