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.

Identifying, interpreting, and managing soil constraints are major challenges, especially when multiple constraints occur in the same soil at various depth zones. Although amelioration tools and strategies are available to manage some of these constraints, field adoption of these technologies is a major challenge to the farming community. Soil Constraints and Productivity helps in identifying and understanding soil constraints, focusing on management practices to alleviate problems associated with these restrictions, and their impacts on crop productivity. Soil Constraints and Productivity aims to: Describe various strategies suitable for mitigating soil constraints Provide data on cost-benefit analysis of managing soil constraints Provide case studies of managing soil constraints to increase productivity Soil is essential for the doubling of major grain production proposed to be necessary to avoid major food security collapses in the future. This book will be a key resource for soil and environmental scientists, farmers, students majoring in agricultural and environmental sciences, and crop consultants.

This is the first of two volumes that together provide a global overview of the impact of agriculture on soil degradation, tracing the most critical drivers like the use and abuse of agrochemicals, mechanization, overgrazing, irrigation, slash and burn agriculture, and the use of plastics. This book covers the main effects of agriculture practices on soil degradation in several countries from Africa, America, Asia, and Oceania, and it elucidates the impact of chemical agents on soil quality, namely, the use of fertilizers, herbicides, pesticides, soil acidification and microplastics pollution. In these continents, a large number of the population depend on agriculture, which sets an enormous pressure on the ecosystems. Divided into 13 chapters, the book offers authoritative contributions about the fundamental soil degradation problems in countries such as Argentina, Australia, Peru and Bolivia, Brazil, Chile, China, Colombia, India, Israel, Kenya, Mexico, South Africa, the United States of America. As soil degradation issues are often linked with biodiversity loss and poverty, readers will also find in this book an important discussion of the different social, economic, political, and environmental aspects contributing to soil quality and sustainable management. Given the breadth and depth of its coverage, the book offers an invaluable source of information for researchers, students, environmental managers and policymakers alike.

This updated and revised second edition brings geopedology issues into the current context. This new edition extends the work on popular topics such as digital soil mapping, GIS and landscape mapping, and it also gives valuable insight with up-to-date theoretical discussions and new application with relevant case studies. This textbook offers a proven approach for reliable mapping of soil-landscape relationships to derive information for policy, planning and management at scales ranging from local to regional. Filled with didactic elements such as case studies, visual aids (maps, charts and figures), questions and answers, the book is of interest to geohazard studies, land use conflict analysis, land use planning, land degradation assessment, and land suitability analysis. Soil is a vital resource for society at large and an important determinant of the economic status of nations. The intensification of natural disasters and the increased land use competition for food and energy have raised awareness of the relevant role the pedosphere plays in natural and anthropogenic environments. Recent papers and global initiatives show a renewed interest in soil research and its applications for improved planning and management of this fragile and finite resource.

This book reviews the potential mechanisms in arbuscular mycorrhizas (AMs), in the hope that this can help arbuscular mycorrhizal fungi (AMF) to be more used efficiently as a biostimulant to enhance stress tolerance in the host plants. AMF, as well as plants, are often exposed to all or many of the abiotic and biotic stresses, including extreme temperatures, pH, drought, water-logging, toxic metals and soil pathogens. Studies have indicated a quick response to these stresses involving several mechanisms, such as root morphological modification, reactive oxygen species change, osmotic adjustment, direct absorption of water by extraradical hyphae, up-regulated expression of relevant stressed genes, glomalin-related soil protein release, etc. The underlying complex, multi-dimensional strategy is involved in morphological, physiological, biochemical, and molecular processes. The AMF responses are often associated with homeostatic regulation of the internal and external environment, and are therefore critical for plant health, survival and restoration in native ecosystems and good soil structure.
