Excerpt from Pneumatic Valves for Automation of Irrigation Systems
Competition for water among domestic, industrial, recreational, and agricultural users in the Western United States is increasing at an alarming rate. Some authorities believe that irri gated agriculture, one of the low efficiency users of Water, could be forced to yield part of its water rights for other purposes unless conservation practices are adopted.
A major cause for inefficient use of water, particularly with surface irrigation systems, is the high labor cost. Coupled with inexpensive water. Farmers are reluctant to use additional labor just to conserve water. Rather, the farmer often adjusts water application time to 'labor patterns dictated by general farm operations. The 12-hour irrigation set used by many farmers often results in excessive percolation and runoff losses, particularly where soils are coarser' textured and intake rates are high. Furthermore, excessive use of water usually leads to drain age and salinity problems that are costly to alleviate.

Paperback. Zustand: New. Print on Demand. This book examines the development and application of pneumatic valves for automated irrigation systems. The author documents the increasing competition for water resources in the Western U.S. and presents a history of automated irrigation systems. The text continues with a detailed description of the structure, function, and laboratory and field testing of several models of pneumatic valves for use in both underground pipelines and open ditches, including their durability, time to open and close, and the varying amounts of air pressure required to close them at various depths. The book concludes with recommendations for future research, particularly portable pneumatic checks and valves with fail-safe features. These innovations have the potential to revolutionize irrigation, saving farmers time, labor, and water, while increasing efficiency and reducing environmental impact.
