Book Synopsis Root Zone Salinity Management Using Fractional Skimming Wells With Pressurized Irrigation: Farmers' skimming well technologies: Practices, problems, perceptions and prospects by : Muhammad Mazhar Saeed
Download or read book Root Zone Salinity Management Using Fractional Skimming Wells With Pressurized Irrigation: Farmers' skimming well technologies: Practices, problems, perceptions and prospects written by Muhammad Mazhar Saeed and published by IWMI. This book was released on 2001 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the short water supply environment of Pakistan, farmers try to minimize the gap between demand and supply of canal water extracting groundwater for irrigation purposes. However, saline groundwater upconing may occur in response to fresh groundwater withdrawals from unconfined aquifer underlain by salty groundwater. Skimming well technology can help controlling this upconing phenomenon. However, in most cases, the small discharges of such wells cannot be efficiently applied on surface irrigated croplands. Pressurized irrigation application systems use small discharge effectively, but the cost and availability of equipment in the local market is a significant constraint. Root zone salinity is also expected to increase if this skimmed groundwater is used for irrigation purposes, particularly in the absence of proper salinity management practices. To address these issues, International Water Management Institute (IWMI), and Water Resource Research Institute (WRRI) of National Agricultural Research Centre (NARC), Mona Reclamation Experimental Project (MREP) of Water and Power Development Authority (WAPDA) are collaborating to undertake an applied research under the Project, Root Zone Salinity Management Using Fractional Skimming Wells with Pressurized Irrigation.

Root zone salinity management using fractional skimming wells with pressurized Irrigation: proceedings of the Project-End Workshop 2003 written by Asghar, Muhammad Nadeem and published by IWMI. This book was released on 2003-03-03 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detailed hydro-geological investigations were carried out while implementing SCARPs in the Chaj Doab. These investigations yielded a data set of groundwater quality at different depths of the aquifers (spatial) especially in the SCARP-II saline zone. In MREP area, 138 public tubewells, having strainers from 30-35 m till 60-75 m depth of the aquifer, were installed during the 1970s to help meet the irrigation water demand at farm level. The MREP, who was made responsible for operation and maintenance of these deep tubewells, continuously monitored the performance of these tubewells as well. Therefore, the pumped groundwater quality data (temporal) of these spatially distributed tubewells was also available. This data availability served as a basis for site selection using GIS analysis.The GIS analysis, which was used in classifying different groundwater quality zones, helped in selecting fifteen villages (thirteen in MREP area and two in SCARP-II saline zone) that have hydro-geological potential for installing and operating skimming wells. In these selected villages, preliminary survey was carried out to get information on the farmers' willingness to use skimming well technology. Based on the GIS analysiS and preliminary survey, different sites in six villages (two in SCARP-II saline zone, and four in SCARP-II non-saline zone) were selected to carry out the Diagnostic AnalysiS (DA) for investigating the hydro-salinity and hydro-geological conditions of the aquifer. Based on the DA results, four villages for the Participatory Rural Appraisal (PRA) to assess farmers' practices and perceptions in opting for skimming well technologies.

Book excerpt: Microbe Mediated Remediation of Environmental Contaminants presents recent scientific progress in applying microbes for environmental management. The book explores the current existing practical applications and provides information to help readers develop new practices and applications. Edited by recognized leaders in the field, this penetrating assessment of our progress to date in deploying microorganisms to the advantage of environmental management and biotechnology will be widely welcomed by those working in soil contamination management, agriculture, environment management, soil microbiology, and waste management. The polluting effects on the world around us of soil erosion, the unwanted migration of sediments, chemical fertilizers and pesticides, and the improper treatment of human and animal wastes have resulted in serious environmental and social problems around the world, problems which require us to look for solutions elsewhere than established physical and chemical technologies. Often the answer lies in hybrid applications in which microbial methods are combined with physical and chemical ones. When we remember that these highly effective microorganisms, cultured for a variety of applications, are but a tiny fraction of those to be found in the world around us, we realize the vastness of the untapped and beneficial potential of microorganisms. Explores microbial application redressing for soil and water contamination challenges Includes information on microbial synthesized nanomaterials for remediation of contaminated soils Presents a uniquely hybrid approach, combining microbial interactions with other chemical and physical methods
Book Synopsis Soil Salinity under Irrigation by : I. Shainberg
Download or read book Soil Salinity under Irrigation written by I. Shainberg and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of irrigation in the world's agriculture is rapidly increasing. Although it is practised on a large scale mainly in arid and semi-arid zones, supplementary irrigation is becoming popular in semi-humid regions as well. The record of irrigation speaks for itself in terms of increased crop production. However, the question remains as to how permanent the achievement may be. Judging from history, it seems that irrigation eventually failed in many regions because the knowledge and technology available to society at the time were incapable of coping with the problems created. Undoubtedly soil salinity is the most prevalent and widespread problem limiting crop productivity in irrigated agriculture. It has, therefore, attracted the attention of the scientific community since the advent of modern agronomic research. Through the past six to seven decades a considerable body of information has been accumulated, which has promoted the understanding of the principles involved and helped to develop the technology for coping with the problems. Our present knowledge, if judiciously applied, is adequate for coping with many of the salinity problems resulting from mismanagement of irrigation and drainage. But for this knowledge to be used, it has to be generally known and understood and be re-examined from time to time.
