Book Description
Soil organic matter is a reservoir for plant nutrients, provides water-holding capacity, stabilizes soil structure against compaction and erosion, and thus determines soil productivity. All agriculture to some degree depends on soil organic matter. It has long been known that soil organic matter declines when land is taken into cultivation, and that the productivity of new agricultural land is governed by fertility contributions from decomposing natural organic matter. The expansion of agriculture to ever new and more fragile lands, particularly in tropical and developing regions, causes environmental degradation with local effects on soil quality, regional effects on landscape integrity and water quality, and global effects on carbon cycles and the atmosphere. This book summarizes current knowledge of the properties and dynamics of soil organic matter in the tropics, its role in determining soil quality, its stability and turnover, and the options for management in the context of tropical landuse systems, for a readership of resource scientists, economists and advanced students. Maintenance of organic matter is critical for preventing land degradation. Case studies and practical applications are therefore an important part of the book, as are the exploration of future directions in research and management.

Book Description
Fertilizers have been used extensively around the globe since the Green Revolution, due to the high subsidies. However, extensive fertilizer use exacerbates soil degradation and causes yield stagnation, and as a result threatens food security and soil sustainability, especially in developing countries. This means that sustainable soil and environmental management are vital to provide food and nutritional security for present and future generations. This has led to the International Union of Soil Science (IUSS) declaring 2015-2024 the International Decade of Soils. This book focuses on the impact of sustainable management of soil and environment on improving the functioning of soil-ecosystems and agronomic productivity, and also discusses food security, nutrient cycling, recent advances in INM technologies, eco-friendly cultivation, agricultural practices to reduce greenhouse gas (GHG) emissions, as well as conservation agriculture and its effects, and strategies for soil sustainability. Offering a comprehensive overview of management in the context of the sustainability of soil and the agroecosystems that it supports, it demonstrates the options available and provides insights into restoring soil health and matching soil nutrient supply with crop demand to ensure nutritional security in an eco-friendly environment.

Book Description
Soil Fertility Improvement and Integrated Nutrient Management: A Global Perspective presents 15 invited chapters written by leading soil fertility experts. The book is organized around three themes. The first theme is Soil Mapping and Soil Fertility Testing, describing spatial heterogeneity in soil nutrients within natural and managed ecosystems, as well as up-to-date soil testing methods and information on how soil fertility indicators respond to agricultural practices. The second theme, Organic and Inorganic Amendments for Soil Fertility Improvement, describes fertilizing materials that provide important amounts of essential nutrients for plants.The third theme, Integrated Nutrient Management Planning: Case Studies From Central Europe, South America, and Africa, highlights the principles of integrated nutrient management. Additionally, it gives case studies explaining how this approach has been implemented successfully across large geographic regions, and at local scales, to improve the productivity of staple crops and forages.

Book Description
Soil—The Basis of All Terrestrial Life Ancient civilizations and cultures—Mayan, Aztec, Mesopotamian, Indus, and Yangtze—were built on good soils, surviving only as long as soils had the capacity to support them. In the twenty-first century, productive soil is still the engine of economic development and essential to human well-being. The quality of our soil resources, however, is threatened by human-induced and natural perturbations. World Soil Resources and Food Security takes an in-depth look at the availability and status of soil resources in the context of the growing demands of an increasing world population and rising expectations of living standards. This timely reference presents current information on the soil resources available for food production. Presenting innovative strategies for soil and water management, it discusses how to maintain or improve the world’s soil resources in order to increase food production. With the majority of the world’s 1.02 billion food-insecure people concentrated in South Asia and sub-Saharan Africa, several chapters focus on soil resources in these regions. Contributions from renowned scientists deal with topics including: Global food situations World soil resources Soil resources of humid Asia and their acidification Soil resources of South Asia Properties and management of Vertisols Use of radioisotopic techniques in soil management The potential of rain-fed agriculture in the semiarid tropics The status of land degradation Nutrient balance in sub-Saharan Africa The book concludes by outlining the need for further research to generate credible data on soil resources and degradation. This volume is a useful resource for those interested in the state of the soils of the world in relation to food security and environmental quality.

Book Description
This book brings together the essential evidence and policy opportunities regarding the global importance of soil carbon for sustaining Earth's life support system for humanity. Covering the science and policy background for this important natural resource, it describes land management options that improve soil carbon status and therefore increase the benefits that humans derive from the environment. Written by renowned global experts, it is the principal output from a SCOPE rapid assessment process project.
