Download or read book Saline and Alkaline Soils in Latin America written by Edith Taleisnik and published by Springer Nature. This book was released on 2020-09-26 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the first comprehensive overview of saline and alkaline soils in Latin America, known for having one of the most extensive surface of salt-affected soils in the world. It is organized along two main axes: soils and vegetation. The book discusses the occurrence of such soils in the region, focusing mainly in management strategies for their sustainable use, and it presents accounts of natural vegetation and crops in the various environments of the region. Social impacts of such conditions and ongoing projects to overcome them are considered. Likewise, the book highlights physiological mechanisms that are responsible for the negative effects these soils exert on crops and forest resources and determine vegetation distribution in them. Plant breeding challenges and new perspectives for such environments are discussed. Technologies such as irrigation and drainage are included. The readership includes soil and plant scientists, as well as policy makers.
Download or read book Handbook of Saline and Alkali Soils Diagnosis Reclamation and Management written by S.K. Gupta and published by Scientific Publishers. This book was released on 2019-05-11 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
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.
