Book Description
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.

Book Description
This book presents a newly designed dynamic fluidic sprinkler (DFS) to improve hydraulic performance of the existing complete fluidic sprinkler (CFS) under low-pressure conditions. Sprinkler irrigation has high prospects for improving water management in crop production. In recent years, low-pressure water-saving has become an important research content in the field of sprinkler irrigation. It introduces the effect of riser height on rotation uniformity and application rate of the dynamic fluidic sprinkler. It also discusses the intelligent sprinkler irrigation technologies for autonomous and remote sensing system. This book will be a useful reference for researchers and professionals in the field of agriculture and irrigation.

Book Description
This book contains previously unpublished & practical design & management information on all forms of drip & microirrigation for agricultural crops. This book benefits from over 30 years of drip/micro design & management experience by the authors in addition to information gleaned from dozens of recent visits to growers using the latest versions of drip/micro. This book is not a repeat or conglomeration of published research. It is meant to satisfy questions by students, designers, & growers who must make hard decisions in the field. Major sections deal with benefits & problems associated with various forms of buried drip. Complete design examples are given for 3 irrigation systems, & new design criteria are provided for pipe sizing of buried drip systems. This book is a must for anyone contemplating practical drip/micro design & management. To order, contact; Irrigation Training & Research Center, Cal Poly, San Luis Obispo, CA 93407; 805-756-2434.

Book Description
Sprinkler irrigation is not new, but its use on other than special crops and on the whole of family-size farms has spread widely in recent yars. Two general types of sprinkler equipment are in general use and are covered in the report, namely, perforated pipe and rotary sprinklers. Pipe lines supplying water to sprinklers may be either fixed or portable. the former are often buried. The latter are made of galvanized sheet or aluminum; usually the latter because of its light weight. Portable lines have quick-acting couplings. Sprinklers are used on large areas west of the Cascade mountains and Sierra Nevada in Oregon, Washington, and California, chiefly on vegetables, fruits and pastures; anorchards in eastern Oregon and Washington; on vegetables and fruitsin the lower Rio Grande Valley of Texas and on the Atlantic seaboard; and on scattered farms throughout the country. They are used successfully on all kinds of crops in one or more sections of the country. The use of sprinklers brings two categories of land into irrigated crop production which otherwise cannot be so used. these are land on which surface methods of applying water are impossible or extremely difficult and land on irrigated farms which is taken up by irrigation channelsif surface methods are used. The use of sprinklers on sandy or steeply sloping heavy soils will result in water savings, often of considerable magnitude. In so far as the general water supply is concerned, these savings, however, are sometimes more apparent than real...

Book Description
This report contains a collection of papers from a workshopâ€"Strengthening Science-Based Decision-Making for Sustainable Management of Scarce Water Resources for Agricultural Production, held in Tunisia. Participants, including scientists, decision makers, representatives of non-profit organizations, and a farmer, came from the United States and several countries in North Africa and the Middle East. The papers examined constraints to agricultural production as it relates to water scarcity; focusing on 1) the state of the science regarding water management for agricultural purposes in the Middle East and North Africa 2) how science can be applied to better manage existing water supplies to optimize the domestic production of food and fiber. The cross-cutting themes of the workshop were the elements or principles of science-based decision making, the role of the scientific community in ensuring that science is an integral part of the decision making process, and ways to improve communications between scientists and decision makers.
