Book Description
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.

Engineering Practices for Management of Soil Salinity

Engineering Practices for Management of Soil Salinity PDF Author: S. K. Gupta
Publisher: CRC Press
ISBN: 1351171070
Category : Science
Languages : en
Pages : 462

Book Description
Abiotic stresses are known to adversely impact agricultural productivity on millions of hectares globally, and it is projected that these problems are likely to increase, primarily due to anthropogenic interventions as well as climatic changes. Understanding abiotic stresses—especially salt stress on soil—calls for an interdisciplinary approach because salt-stressed soils need hydro-technical, chemical, and agronomic interventions as well as an understanding of plant response when exposed to these stresses. This volume explores and conveys the latest information on emerging technologies in the management of abiotic salt stress and their field applications. It brings together experts from various fields (academia, technology, and engineering) to provide the latest information and knowledge on this important challenge.

Category : Technology & Engineering
Languages : en
Pages : 158

Book Description
Soil science is a specialized branch of agriculture which associated with the different areas of soil pedology, soil physics, soil chemistry, soil biology, soil fertility, plant nutrition etc. It is, therefore, worthwhile to understand the nature and behavior of natural resources for sustainable agricultural production. Fundamentals of Soil Science assembles and summatizes pertinent available information for the students of agriculture in general and soil science in particular. This text book is a comprehensive more and will meet the growing need of soil science of graduate and post graduate students at university level agricultural education. This book covers the course contents of competitive examinations like IAS, IFS, PCS, ARS, banking services, B.Sc./M.Sc./Ph D. (Ag) admission, states and national levels of different competitive examinations in agriculture. The entire book is prepared in most simple, clear, talking language, comprehensive and short descriptive type of questions so that the concept could be easily understand by the readers in short times.

Publisher: Scientific Publishers
ISBN: 9388812298
Category : Technology & Engineering
Languages : en
Pages : 247

Book Description
The term "alkali soil"is employed to refer to soils that have a high exchangeable-sodium-percentage; and "saline soil" is used in connection with soils having a high value for the electrical conductivity of the saturation extract. This handbook was first issued in multilithed form in 1947, and it has been widely distributed in this country and abroad. The handbook is intended primarily as a practical guide for those who are confroted with soil, plant, and water problems involving salinity and alkali The first five chapters provide a basis for the evaluation and interpretaion of measure-ments The procedures and measuring methods given in chapters 6,7, and 8 are those with which the Laboratory has had experience, and they are believed to have general applicability in the diagnosis and improvement of saline and alkali soils. This handbook is the result of the combined efforts of the entire staff of the salinity Laboratry.

ISBN: 9387991547
Category : Science
Languages : en
Pages : 150

Book Description
Rapidly shrinking biodiversity resources now have vital linkages to sustainability of climate and habitable environment; unsustainability of agriculture and decline in socio-economics of human values. This book considers the history of Planet Earth, formation of the continents, origin, and evolution of Life from the beginning till the present. The present status of management of agricultural production systems, Integrated Pest Management, genetically modified crops and organic agriculture besides the future role of pesticide industry in promoting holistic agriculture and conservation of natural biodiversity resources have also been discussed. Social impact of shrinkage of biodiversity resources beyond the biological means of their renewal together with the neglect of basic human rights to food, nutrition and health security have been discussed. A new beginning and agenda for future development of biodiversity resources have been proposed.

Soil Analysis: Recent Trends and Applications

Soil Analysis: Recent Trends and Applications PDF Author: Amitava Rakshit
Publisher: Springer Nature
ISBN: 9811520399
Category : Technology & Engineering
Languages : en
Pages : 340

Book Description
Soil analysis is critically important in the management of soil-based production systems. In the absence of efficient methods of soil analysis our understanding of soil is pure guesswork. Ideally the pro-active use of laboratory analysis leads to more sustainable soil productivity. Unfortunately, most of the world’s agriculture is still reactionary, waiting for obvious yield declines to occur before taking action to identify the reasons. The modern soil laboratory is pivotal to informing soil managers what adaptive practices are needed to address chemical and physical imbalances before they occur, and the intelligent adaptive use of laboratory data not only greatly speeds up and reduces the cost of empirical soil study, but can even render it unnecessary. This book provides a synopsis of the analytical procedures used for soil analysis, discussing the common physical, chemical and biological analytical methods used in agriculture and horticulture. Written by experienced experts from institutions and laboratories around the globe, it provides insights for a range of users, including those with limited laboratory facilities, and helps students, teachers, soil scientists and laboratory technicians increase their knowledge and skills and select appropriate methods for soil analysis.
