Ec81-760 How To Adjust Vertical Turbine Pumps For Maximum Efficiency, Thomas W. Dorn, Mark A. Schroeder, Paul E. Fischbach

University of Nebraska-Lincoln Extension: Historical Materials

The Agricultural Engineering Department has tested more than 500 pumping plants in the past 25 years. The average performance indicates that about 30 percent of the energy used for irrigation could be saved if all pumping plants operated at the Nebraska Performance Criteria.

There were many causes for poor pumping plant performance. Major causes were poor power unit performance, and poor pump performance often caused by improper pump adjustment.

This circular discusses proper pump adjustment to attain maximum efficiency.

G81-562 Guidelines For Using Pipewick And Other Selective Applicators, William E. Lueschen, Alex R. Martin, John D. Furrer

University of Nebraska-Lincoln Extension: Historical Materials

The use of selective applicators is being rapidly adopted by farmers to supplement their weed control programs. A low-cost method of removing tall, escaped weeds from short stature crops, selective application is also environmentally appealing since the herbicide is applied only to the target weeds and thus only small amounts of herbicides are used.

There are three basic types of applicators available: ropewicks, recirculating sprayers (RCS), and carpeted rollers. This NebGuide discusses each applicator and how it can be used on the farm.
