Agricultural Salinity review and administration, moment variation, considers all over the world salinity and hint point administration in irrigated agriculture and water offers. This up to date version presents a connection with aid maintain irrigated agriculture and integrates modern techniques and administration practices. It covers technical and clinical features of agricultural salinity mangement, in addition to environmental, monetary, and felony matters. subject matters contain: nature and quantity of agricultural salinity; analysis of salinity difficulties and choice of keep an eye on practices; soil reaction to saline and sodic stipulations; plant responses to saline and sodic stipulations; long term regional-scale modeling of soil salinity; case research of San Joaquin Valley, California; institutional and salinity concerns at the higher Rio Grande; and viability of irrigated agriculture with increasing area and time. the second one version of MOP seventy one is efficacious to water execs, engineers, scientists, practitioners, and educators attracted to constructing and handling ever extra limited water provides world wide

Example text

By the fall of 2008, all the chapters had been submitted. They were technically reviewed by the Task Committee (each chapter was reviewed by a member of the Committee) and revised by the authors. The draft document, finalized by the Committee, was given to ASCE for review. The Irrigation and Drainage Council appointed a Review Committee of three members of ASCE, comprising a balance of interests, with expertise in the subject matter. They were independent from the Task Committee and were not authors.

Available data on relative crop tolerances to salinity and specific ions and elements are compiled in Chapter 13 (Tables 13-1 through 13-5). Such 30 AGRICULTURAL SALINITY ASSESSMENT AND MANAGEMENT salt-tolerance data cannot provide accurate, quantitative values of crop yield losses from salinity for every situation. Actual response to salinity varies with many factors, including climate, soil conditions, agronomic practices, irrigation management, crop variety, stage of growth, and salt composition.

Historical records for the past 6,000 years reveal that numerous societies based on irrigated agriculture have failed. One of the most highly publicized is ancient Mesopotamia, now Iraq. C. C. This problem (Jacobsen and Adams 1958) stemmed from a dispute between two Sumerian cities, Umma and Girsu, over land and water NATURE AND EXTENT OF AGRICULTURAL SALINITY AND SODICITY 13 FIGURE 1-8.
