Download or read book Managing Organic Matter in Tropical Soils Scope and Limitations written by Christopher Martius and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Sustainable Management of Soil and Environment written by Ram Swaroop Meena and published by Springer Nature. This book was released on 2019-10-02 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Recarbonizing global soils A technical manual of recommended management practices written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2021-09-07 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decades, soil organic carbon (SOC) attracted the attention of a much wider array of specialists beyond agriculture and soil science, as it was proven to be one of the most crucial components of the earth’s climate system, which has a great potential to be managed by humans. Soils as a carbon pool are one of the key factors in several Sustainable Development Goals, in particular Goal 15, “Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification and halt and reverse land degradation and halt biodiversity loss” with the SOC stock being explicitly cited in Indicator 15.3.1. This technical manual is the first attempt to gather, in a standardized format, the existing data on the impacts of the main soil management practices on SOC content in a wide array of environments, including the advantages, drawbacks, and constraints. This manual presents different sustainable soil management (SSM) practices at different scales and in different contexts, supported by case studies that have been shown with quantitative data to have a positive effect on SOC stocks and successful experiences of SOC sequestration in practical field applications. Volume 2 includes a description of hot spots of SOC stocks. This manual defines hot spots of SOC as areas that represent a proportionally little of the global land surface but on which SOC storage is highly effective; bright spots as large land areas with low SOC stocks per km2 that represent a potential for further carbon sequestration.

Download or read book World Soil Resources and Food Security written by Rattan Lal and published by CRC Press. This book was released on 2011-09-13 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
