Download or read book Genesis and Management of Sodic Alkali Soils written by S.K. Gupta and published by Scientific Publishers. This book was released on 2017-10-01 with total page 332 pages. 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 Salinity Tolerance in Plants Methods Mechanisms and Management 2nd Ed written by B. K. Garg and published by Scientific Publishers. This book was released on 2019-03-01 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salinity tolerance in plants is a complex problem encompassing numerous morphological, physiological and biochemical processes and adaptations at the cellular, sub-cellular and whole plant levels. The book comprising eleven chapters deals with diverse aspects of salt tolerance including plant response to salinity and sodicity, crop tolerance at different growth stages and criteria for evaluating the same. The mechanism of salt injury viz. osmotic, ionic and nutrient imbalance has been dealt with, adopting an integrated appraoch. Likewise, the recent information on photosynthesis, respiration, carbohydrate, nitrogen and protein metabolism, enzyme dynamics and plant hormones, as well as nodulation and symbiotic nitrogen fixation in legumes has been elaborated comprehensively. Special attention has been given to the interaction between essential nutrients and salinity as it is vital for alleviation of adverse effects of salt stress. The synthesis of knowledge on different mechanisms of salt resistance, including osmoregulation with organic and inorganic solutes has also been presented. Various methods of introducing salt tolerance in plants such as breeding, genetic variations, physiological approaches, tissue culture, somaclonal variation, somatic hybridation and recombinat DNA technology have been discussed. The nature and properties of salt affected soils and groundwaters and principles for amelioration and management of these critical problems have been included in this book. Furthermore, Afforestation and Agroforestry techniques for salt affected soils with emphasis on salt tolerant tree species and suitable tree crop combinations also find their much needed due space in the present book.

Download or read book Eucalypt Ecology written by Jann Elizabeth Williams and published by Cambridge University Press. This book was released on 1997-11-13 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dominant trees of Australia, eucalypts make up a remarkable genus. This authoritative volume provides current reviews by active researchers of many disciplines, including evolutionary history, genetics, distribution and modelling, the relationship of eucalypts to fire and nutrients, ecophysiology, pollination and reproductive ecology, interactions between eucalypts and other co-existing biota (including fungi, invertebrates and vertebrates), and conservation and management. Together these reviews shed light on the reasons for the great success of eucalypts in Australian environments, and provide a comprehensive summary for comparison with the ecology of major woody plant genera in other continents. This volume is of particular relevance to Australian ecologists, but also provides a stimulating perspective to students of vegetation ecology in all continents.

This book was released on 2016-02-11 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Land degradation caused by salinity and waterlogging is a global problem afflicting about one billion hectares and endangering the food security of at least 75 countries. Since the social, economic and environmental costs of on and/off-farm reclamation techniques are high, agroforestry is now emerging as a potential tool, not only for arresting salinity and waterlogging, but also for other environmental services like mitigating climate change, sequestering carbon and restoring biodiversity. This publication addresses the vital issues, principles and practices related to rehabilitation using agroforestry and includes many site-specific case studies from a number of the world’s typical catchments. Written by leading researchers, the book is a must, not only for scientists whose research interests lie in soil salinity, waterlogging and poor-quality waters, but also policy makers, environmentalists, students, and educationists alike. More importantly, it contributes to reversing the salinity trends and ensuring the livelihoods of resource-poor farming families living in these harsh agro-ecosystems.

Available in PDF, EPUB and Kindle. Book excerpt: Artificial drainage is essential to sustain irrigated agriculture, in order to control the water table and avoid waterlogging and salinisation. Biodrainage systems rely on vegetation rather than mechanical means to remove excess water, and can provide a cost-effective and environmentally friendly drainage option. This publication presents a range of formally published and unpublished literature on the current level of knowledge of biodrainage, in order to inform further research and promote pilot testing schemes.
