Available in PDF, EPUB and Kindle. Book excerpt: Land and water, the two crucial natural resources for agriculture, are decreasing as a result of burgeoning population of the country. At the same time, various forms of degradation are taking a toll on the productivity of these resources so much so that large areas have been taken out of plough. Current assessment reveal that already 6.73 million ha area has gone out of cultivation because of excessive salts or high sodicity and this area is likely to expand to 20 million ha by 2050 because of the faulty irrigation and drainage water management practices being adopted in irrigation commands. Of the current affected area, more than 50% is sodic in nature, which requires some kind of chemical amendment for reclamation. While our knowledge and understanding of the causes, nature and harmful effects of sodic soils have tremendously increased, availability of gypsum on account of environmental problems on its mining has caused concerns. Apparently, there is a need to push for other amendments especially the industrial wastes and publish the information in practical terms for various stakeholders. This book is an attempt in this direction. Taking into account the widely varying needs of the clients, the chapters of this book have been organized to include history, origin and genesis of sodic lands, basic principles of diagnosis, nature and properties of sodic lands, amendments, reclamation package and alternate land management. Since sodic water irrigation is one of the factors in the formation of sodic lands, a separate chapter deals with this issue highlighting the extent and distribution, chemical characteristic and management options for the use of sodic water. The economic analysis procedures and socio-economic issues of sodic land reclamation are included in a separate chapter with appropriate case studies. Since latest scientific information on new technologies with case studies is included, we believe that this book is an improvement over the existing books and is a useful addition to the literature on this subject. In our view the information contained in this book would be handy to field practitioners in the Government Departments and NGOs to plan and undertake large sodic land reclamation projects. Since the basic principles and practices have been very well elucidated, the book can be used as a text book in agricultural and engineering colleges. It can also be used as a source material in training programs being organized by various scientific organizations. We believe that the book would prove to be a handy reference resource to all those interested in sustainable irrigated agriculture for the food and nutritional security of the nation.

Download or read book Crop Production in Salt Affected Soils written by I.C. Gupta and published by Scientific Publishers. This book was released on 2019-04-01 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: The course work for various degree programs are constantly revised and or new courses added so that the future teachers, researches and planners are able to face the new emerging challenges. The environmental concerns of irrigated agriculture in the form of water logging and soil salinity are expanding and impacting food grains production. These challenges are commonly articulated at various forums. Thus, reclamation, management and crop production practices of waterlogged salt affected soils have been introduced as a subject in agricultural and agricultural engineering colleges. Since there is a general lack of a good textbook on this subject, authors have attempted to fill this gap through the current publication titled `Crop Production in Salt Affected Soils´. It comprehensively deals with the fundamentals of land reclamation principles and crop production practices. It has been divided into 16 Chapters. The book begins with general introduction comprising of categorization of salt affected soils, extent and distribution and nature and physical, chemical and biological properties. Other chapters includes basic information on on-farm land development, hydrology, irrigation practices, drainage methods, leaching, soil salinization, chemical amendments, and new innovative techniques including agronomic and cultural practices related to land reclamation. Crop production practices for select cereal, oil seeds, sugar, fiber and forage, green manure crops, grasses and forest plantations are also included. Chapter sixteen covers the economic evaluation and social issues involved in land reclamation programs. A Glossary of terms has been added for quick overview of the terms used in the book. The textbook designed and developed for the undergraduate/post graduate students of agricultural/agricultural engineering has been profusely illustrated so that students are able to visualize the processes and phenomena being dealt with. Besides serving as a text book, it will prove to be a handy resource book to conduct specialized training programs on land reclamation. We believe that the book will find its due place in the shelves of students and teachers, field functionaries and college libraries of state agricultural universities and civil engineering colleges.
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.

Download or read book Salt affected Soils and Marginal Waters written by Ranbir Chhabra and published by Springer Nature. This book was released on 2022-01-01 with total page 729 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents systematic scientific appraisal, classification, genesis and viable technologies for reclamation and management of salt-affected soils and marginal quality waters across India and several other countries. Nature, solubility and geo-chemical mobility of salts have been provided as basis for the development of alkali and saline soils and groundwaters under specific agro-hydro-ecological regions. Chemical amendment (gypsum) based reclamation technology of alkali soils and related pre and post-reclamation water, nutrient and crop management interventions, including re-sodification issues have been comprehensively addressed. Features and operational guidelines of surface, subsurface, vertical and bio-drainage systems have been thoroughly discussed; likewise, amelioration of irrigation induced saline soils in inland and coastal regions and preventive measures for control of salinity and waterlogging along with environmental trade-offs. Practical approaches for amelioration and judicious use of saline, alkali, high SAR- saline and waste waters have been synthesized for different cropping and agro- forestry systems. Emerging issues on use of industrial by-products as amendments for alkali soils, physiological aspects of salt resistance, anatomical and biochemical mechanism of submergence tolerance, specific ion effects of poor quality waters, crop diversification, groundwater recharge, rejuvenation of tsunami affected coastal soils, safety against occurrence of poisonous gas in tube well pits, paddy straw burning and others have been adequately deliberated upon. Combining scientific principles with field experiences, the book is expected to serve as a useful knowledge base for research workers, teachers and students of soil science, agronomy, plant breeding, forestry, irrigation engineering, extension workers, environmentalists and planners associated with reclamation and management of salt affected soils and waters on sustainable basis in developing and developed countries.
