This book, first published in 1990 and reprinted here, is a comprehensive, state-of-the art reference on the design principles and management techniques of two primary agricultural irrigation methods. The book presents a systematic approach to the optimal design, management and operation of these two systems. Focusing on the synthesis of the entire design process, the authors present the chapters in the sequence used to design systems with the analytical material presented and demonstrated in a concise manner. For the first time in any book, Sprinkle and Trickle Irrigation offers complete design strategies and presentations for all of the major types of sprinkle and trickle systems: - Periodic-move - Center-pivot - Traveling sprinkler - Linear-moving - Set sprinkler - Drip, spray and line-source Sequential sample calculations that involve the steps in the design of typical irrigation systems are used extensively. As the book progresses, these calculations become more comprehensive and are linked together to form complete design packages for the various types of pressurized systems. The book also presents a section on selecting pressurized irrigation systems, a review of soil-plant-water relationships, unique insight into pipeline hydraulics and economics, design specifications for fertilization and frost control, a glossary and an annotated bibliography of ASAE Standards for Pressurized Irrigation Systems. Sprinkle and Trickle Irrigation is an important practical reference for agricultural engineers, irrigation system designers and agricultural managers, as well as a vital text for professors and researchers in agricultural engineering. "Sprinkle and Trickle Irrigation presents beginning-to-end coverage of the processes and computations needed in the planning and design of sprinkle and trickle irrigation systems. The textbook is created for the thinking person who desires more than cookie-cutter recipes or simple, routine "rule-of-thumb" designs. Rather, the authors of Sprinkle and Trickle Irrigation present concise rationale and philosophy behind each computation formula, figure and table. They decouple "recommended" design parameters into underlying components that can be recoupled at the time of the design to apply to specific cases and situations. In the process, the reader gains visualization skills that allow him/her to peer "inside" an irrigation system, both hydraulically, economically, and operationally. Sprinkle and Trickle Irrigation is a classic design text and reference that should be on every practitioner's desk. The chapters on center-pivot, linear-move and travelling sprinklers go well beyond other current texts. Solid and encompassing economics are infused into all design topics, including application, distribution, and pumping systems. I have lectured out of Sprinkle and Trickle Irrigation for twelve years at the university-senior level. I am confident that all students who completed this design course know not only how to design efficient and effective pressurized irrigation systems, but also know why they use the procedures that they use."

This textbook is a comprehensive volume on sprinklers and drip irrigation and covers all the basic and fundamentals concepts related to these topics. It is the first book to consider relative-flow-ratio as an evaluation criterion for both sprinkler and drip irrigation designs. It also discusses various types of sprinklers (used for irrigation), their complex layouts, design methodologies, selection criteria explained with practical examples, and their operations and maintenance under different conditions. In addition to operation and maintenance of drip irrigation components, the book also explains the drip irrigation hydraulics and various design aspects and the effect of the same on their performance. It also has one important chapter on Rhizosphere modelling which introduces the state-of-the-art technologies in optimal irrigation and fertigation scheduling. Worked out examples and solved problems in the chapters would aid to learning and understanding of the topic among the students. Given the contents, the book will be extremely useful for the undergraduate and postgraduate students of agriculture engineering, irrigation engineering and civil engineering. This textbook will also be useful for researchers, engineers and professionals working in these areas.

This manual gives a practical, in-depth look at sprinkle irrigation in California as used on vegetable crops. 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.

This report is a view of irrigation technologies for smallholders in the context of improving rural livelihoods, especially in regard to the prospects for sub-Saharan Africa. The role of traditional technologies is evaluated and modern water distribution technologies, such as sprinkler and trickle irrigation, are reviewed. A broad classification has been made based on climate and the traditional agricultural background of the local people, which links technology options to specific places--to agricultural regions and to countries.

The aim of this book is quite ambitious: here, we attempt to bridge the gap between soH physicists, agronomists, horticulturists, hydraulic engineers, de signers, manufacturers and users of drip irrigation systems. We believe that progress in drip irrigation hinges on the contributions of professionals made in all related disciplines and their cooperation. The last decade has seen great development in the field of drip irrigation, al though the drip-irrigated area has not increased at the same rate as in the pre vious decade. However, our understanding of the processes involved in water and solute distribution and in plant response has increased vastly. The tools for op timal design of drip systems have improved tremendously. The main progress has been in the development and in the manufacture of sophisticated equipment; not only improved types of emitters and laterals, but also auxiliary equipment such as new filtration systems, controllers and sensors. In this book we highlight the need to maintain a proper balance between the hydraulic design of drip systems and aspects of their management and maintenance. Drip irrigation has a potential for high water use efficiency, but many well-designed systems suffer from bad management. We are indebted to the late Eshel Bresler for his contribution to our under standing of water and solute movement under drip irrigation and its appli cation to system design.

Historically, scientists and laymen have regarded salinity as a hazar dous, detrimental phenomenon. This negative view was a principal reason for the lack of agricultural development of most arid and semi arid zones of the world where the major sources of water for biological production are saline. The late Hugo Boyko was probably the first scientist in recent times to challenge this commonly held, pessimistic view of salinity. His research in Israel indicated that many plants can be irrigated with saline water, even at seawater strength, if they are in sandy soil - a technique that could open much barren land to agriculture. This new, even radical, approach to salinity was clearly enunciated in the book he edited and most appropriately entitled 'Salinity and Aridity: New Approaches to Old Problems' (1966). A decade later, three members of the United States National Science Foundation (NSF), Lewis Mayfield, James Aller and Oskar Zaborsky, formulated the 'Biosaline Concept'; namely, that poor soils, high solar insolation and saline water, which prevail in arid lands, should be viewed as useful resources rather than as disadvantages, and that these resources can be used for non-traditional production of food, fuels and chemicals. The First International Workshop on Biosaline Research was con vened at Kiawah Island, South Carolina, in 1977 by A. San Pietro.
