Book Description
Excerpt from Automation of Surface Irrigation: 15 Years of Usda Research and Development at Fort Collins, Colo Figure 1. Usda pneumatic valve showing ease of installation on standard, alfalfa valve (b). To install, lid (c) is first removed from threaded (d) spider. The threaded stem is inserted through center bushing (e) and then replaced in threaded spider. Normally open valve provides built-ih fail-safe feature in event of air pressure failure.

Book Description
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.

Book Description
Precision agriculture is a reality in agriculture and is playing a key role as the industry comes to terms with the environment, market forces, quality requirements, traceability, vehicle guidance and crop management. These proceedings contain reviewed papers presented at the 12th European Conference on Precision Agriculture. The papers reflect the wide range of disciplines that impinge on precision agriculture - technology, crop science, soil science, agronomy, information technology, decision support, remote sensing and others.

Book Description
With a roster of international contributors, this volume offers an abundance of solutions to address agricultural water management challenges in today’s water-scarce areas of the world. The authors present studies on farmer-friendly irrigation scheduling methods, model-based analysis of crop water requirements, ways to optimize surface irrigation systems, and hydraulic design and management of surface water systems. The book goes on to highlight ways to improve soil properties by taking into account spatial, temporal, and spectral variability in soil properties. The volume also covers various innovative research studies on soil and water productivity of vegetable cultivation under water-stressed areas, application of coir geotextiles, and the role of biofertilizers in controlling soil degradation and maintaining fertile topsoil. Crop management strategies to enhance the efficient use of marginal and saline lands for nonconventional crops are also discussed. The book is divided into four sections, covering: engineering interventions in irrigation management technological interventions in management of soil properties technological inventions for soil and water conservation crop management for non-conventional use This volume will serve as an invaluable resource for academicians, researchers, engineers, agronomists, extension officers, students, and farmers in the broad discipline of agricultural and biological engineering.
