Several textbooks and edited volumes are currently available on general soil fertility but‚ to date‚ none have been dedicated to the study of “Sustainable Carbon and Nitrogen Cycling in Soil.” Yet this aspect is extremely important, considering the fact that the soil, as the ‘epidermis of the Earth’ (geodermis)‚ is a major component of the terrestrial biosphere. This book addresses virtually every aspect of C and N cycling, including: general concepts on the diversity of microorganisms and management practices for soil, the function of soil’s structure-function-ecosystem, the evolving role of C and N, cutting-edge methods used in soil microbial ecological studies, rhizosphere microflora, the role of organic matter (OM) in agricultural productivity, C and N transformation in soil, biological nitrogen fixation (BNF) and its genetics, plant-growth-promoting rhizobacteria (PGPRs), PGPRs and their role in sustainable agriculture, organic agriculture, etc. The book’s main objectives are: (1) to explain in detail the role of C and N cycling in sustaining agricultural productivity and its importance to sustainable soil management; (2) to show readers how to restore soil health with C and N; and (3) to help them understand the matching of C and N cycling rules from a climatic perspective. Given its scope, the book offers a valuable resource for educators, researchers, and policymakers, as well as undergraduate and graduate students of soil science, soil microbiology, agronomy, ecology, and the environmental sciences. Gathering cutting-edge contributions from internationally respected researchers, it offers authoritative content on a broad range of topics, which is supplemented by a wealth of data, tables, figures, and photographs. Moreover, it provides a roadmap for sustainable approaches to food and nutritional security, and to soil sustainability in agricultural systems, based on C and N cycling in soil systems.

Soil Management and Climate Change: Effects on Organic Carbon, Nitrogen Dynamics, and Greenhouse Gas Emissions provides a state of the art overview of recent findings and future research challenges regarding physical, chemical and biological processes controlling soil carbon, nitrogen dynamic and greenhouse gas emissions from soils. This book is for students and academics in soil science and environmental science, land managers, public administrators and legislators, and will increase understanding of organic matter preservation in soil and mitigation of greenhouse gas emissions. Given the central role soil plays on the global carbon (C) and nitrogen (N) cycles and its impact on greenhouse gas emissions, there is an urgent need to increase our common understanding about sources, mechanisms and processes that regulate organic matter mineralization and stabilization, and to identify those management practices and processes which mitigate greenhouse gas emissions, helping increase organic matter stabilization with suitable supplies of available N. Provides the latest findings about soil organic matter stabilization and greenhouse gas emissions Covers the effect of practices and management on soil organic matter stabilization Includes information for readers to select the most suitable management practices to increase soil organic matter stabilization

Good management practices for carbon and nitrogen are vital to crop productivity and soil sustainability, as well as to the reduction of global greenhouse gases and environmental pollution. Since the 1950's, mathematical models have advanced our understanding of carbon and nitrogen cycling at both the micro- and macro-scales. However, many of the models are scattered in the literature, undergo constant modification, and similar models can have different names. Modeling Carbon and Nitrogen Dynamics for Soil Management clarifies the confusion by presenting a systematic summary of the various models available. It provides information about strengths and weaknesses, level of complexity, easiness of use, and application range of each model. In nineteen chapters, internationally known model developers and users update you on the current status and future direction of carbon and nitrogen modeling. The book's coverage ranges from theoretical comparison of models to application of models to soil management problems, from laboratory applications to field and watershed scale applications, from short-term simulation to long-term prediction, and from DOS-based computer programs to Object-Oriented and Graphical Interface designs. With this broad scope, Modeling Carbon and Nitrogen Dynamics for Soil Management provides the tools to manage complex carbon/nitrogen processes effectively.

Soil fertility is one of the most important factors regulating yield and productivity in both the agricultural and natural ecosystems of the tropics, and maintaining soil fertility has become a key challenge to sustainable development in this region. This book presents the ecological processes and management practices which affect soil fertility and then looks at ways to integrate this knowledge to develop economically feasible solutions. Based on a symposium held at the University of Zimbabwe in May 1996, the volume is partly the result of ten years of research by the Soil Biology and Fertility Project in Zimbabwe and includes contributions from researchers in Africa, Asia, Europe and North America. The book is divided into five sections covering nutrient dynamics in soil, decomposition of crop residues, tree-soil-crop interactions in agroforestry and in ecosystem dynamics, and prospects for the future. Essential reading for agronomists, soil scientists and ecologists studying the tropics, this volume is also an important reference for decision-makers in land use and development in tropical countries.

Food insecurity is a fundamental challenge to human welfare and economic growth in Africa. Low agricultural production leads to low incomes, poor nutrition, vulnerability to risk and threat and lack of empowerment. This book offers a comprehensive synthesis of agricultural research and development experiences from sub-Saharan Africa. The text highlights practical lessons from the sub-Saharan Africa region.
