This manual provides practical information on the design, management, and maintenance of the sprinkle irrigation methods commonly used in California for irrigating field and row crops, with a focus on hand-move, wheel line, and portable solid-set systems. Other systems, not commonly used in California are also discussed.
Inside you'll find discussion of management considerations such as when to irrigate, how much water to apply, and how to monitor soil moisture. You’ll also find an overview of uniformity and efficiency, sprinkle lateral design considerations, calculating pressure losses along laterals, factors affecting uniformity, effect of pressure spacing, and wind on catch can uniformity, as well as evaluating and improving sprinkle irrigation systems.
A chapter on energy considerations covers pump selection, factors that affect pumping plant performance, pump performance tests, variable speed drives for pumping plants, and measures to consider to reduce energy use.
Handy tables clearly illustrate key concepts to help you with decision making and trouble-shooting. Contains 46 illustrations and 28 tables, as well as 8 appendices of selected cover-crop coefficient relationships.
* Presents a detailed explanation of system design, operation, and management specific to various types of MI systems
* Analyzes proper use of irrigation technology and its effect to increase efficiency
* Provides an understanding to the basic science needed to comprehend operation and management
* Over 150 figures of designs and charts of systems including, surface drip, subsurface drip, spray/microsprinkler, and more
Alternative methods of irrigation are presented, emphasising the characteristics of each that may make them suitable (or unsuitable) for particular situations. The range of crops under irrigation is very wide, and so too is the range of methods available to get water to them. Horticultural crops are included as well as broadacre crops. This section is followed by technical information of the various components that make up an irrigation system, and their installation.
Irrigation is concerned with providing the optimum soil moisture conditions for plant growth. So to is drainage, in that too much water in the soil will retard growth. Many of the concepts surrounding irrigation are applicable to a consideration of drainage, so the book discusses that technology as well.
