Adjustable Magnetic Coupler, Charles M. Burt

BioResource and Agricultural Engineering

Efficiency in terms of power consumption is vital and continues to be increasingly important. The use of adjustable speed pumps can reduce energy consumption and improve controllability of pressure or flows. One such technology, the MagnaDrive coupler, has been developed for service in a variety of applications.

Pumped Storage: Simple Changes, Big Savings, Charles M. Burt

BioResource and Agricultural Engineering

Several California irrigation districts achieved savings on electrical energy charges by implementing various types of pumped storage systems. Pumped storage uses some type of reservoir to store pumped water at a higher elevation than the original water supply. During times of peak statewide electricity demand, pumping is reduced while water is withdrawn from the reservoir which acts as a buffer.

Load Monitoring System, Charles M. Burt

BioResource and Agricultural Engineering

Arvin-Edison Water Storage District received a loan - from the CEC's loan program for the development of new energy conservation technology - in 1995 to develop a program with variable frequency drives. This report discusses the design of the "Load Monitoring System", cost, the need for such a system, initial start-up challenges, configuration options, and benefits.

Evaluation Of Retrievable Drip Tape Irrigation Systems, Charles M. Burt, Jess T. Barreras

BioResource and Agricultural Engineering

California growers of lettuce, broccoli, celery, and cauliflower have long been leaders in drip tape applications. Starting in the early 1990s, large acreages of buried, subsurface drip irrigation (SDI) were installed with the intent of leaving the tape in the ground for up to 10 years (Burt and Styles, 1999). Tape burial depths were typically 20 - 25 cm below the soil surface. Although yields and irrigation efficiencies typically increased, there were numerous challenges with SDI. Since the tape was buried, such issues occurred as gopher damage, problems with root intrusion, soil back-siphonage when the system was shut off, damage …

Improving Irrigation For Ord Sugar Cane, Jim Engelke, Joe Sherrard, Gae Plunkett, Tim Triglone

Journal of the Department of Agriculture, Western Australia, Series 4

Major changes are underway in irrigation practices for the Ord sugar industry as it moves to implement recent findings on improving irrigation efficiency and managing rising groundwater. Significant improvement in efficiency is expected by more accurately matching water application with crop water requirements and by minimising drainage losses through improved water application techniques.

Based on findings from this work, drying off may not be an appropriate strategy for the ORIA as a means of improving crop sucrose content, but could allow for some reduction in water use towards the end of the crop cycle without adversely impacting on sucrose yield. …
