Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Modeling Carbon and Nitrogen Dynamics for Soil Management written by M J Shaffer and published by CRC Press. This book was released on 2019-08-30 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Carbon, Nitrogen and Phosphorus Cycling in Forest Soils written by Robert G. Qualls and published by MDPI. This book was released on 2019-06-21 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: The majority of carbon stored in the soils of the world is stored in forests. The refractory nature of some portions of forest soil organic matter also provides the slow, gradual release of organic nitrogen and phosphorus to sustain long term forest productivity. Contemporary and future disturbances, such as climatic warming, deforestation, short rotation sylviculture, the invasion of exotic species, and fire, all place strains on the integrity of this homeostatic system of C, N, and P cycling. On the other hand, the CO2 fertilization effect may partially offset losses of soil organic matter, but many have questioned the ability of N and P stocks to sustain the CO2 fertilization effect. Despite many advances in the understanding of C, N, and P cycling in forest soils, many questions remain. For example, no complete inventory of the myriad structural formulae of soil organic N and P has ever been made. The factors that cause the resistance of soil organic matter to mineralization are still hotly debated. Is it possible to “engineer” forest soil organic matter so that it sequesters even more C? The role of microbial species diversity in forest C, N, and P cycling is poorly understood. The difficulty in measuring the contribution of roots to soil organic C, N, and P makes its contribution uncertain. Finally, global differences in climate, soils, and species make the extrapolation of any one important study difficult to extrapolate to forest soils worldwide.

Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book Changes in Soil Carbon and Nitrogen Storage After Conversion from Tussock Grassland to Pine Plantation, Glendhu Catchment, Otago, New Zealand written by Minzi Liu and published by . This book was released on 2016 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Globally, soil and surface litter store 2 to 3 times more organic carbon than vegetation and 3 times more carbon than the atmosphere. The soil organic stock at a soil depth of 1 m is globally about 1500 to 1600 Pg (Pg = 1015 g). The amount of carbon and nitrogen stored in the soil is influenced by many factors. An important factor affecting soil properties, carbon and nitrogen storage is land use and land cover change (LULCC). Conversion of grasslands into tree plantations is common with the aim of increasing aboveground carbon stocks to mitigate climate change. This study investigated the changes that happened in the soil in the Glendhu catchment (Otago, New Zealand) after conversion of tussock grassland to pine plantation 36 years ago. The objectives of this study were to l Quantify the soil carbon and nitrogen stocks to 1 m soil depth l Determine the physical parameters of soil l Investigate the relationships between soil parameters, soil depths and land use types l Investigate the relationships between tussock density and soil carbon density A total of 72 mineral soil cores (to 1 m depth, five depth increments, in total 360 mineral soil samples) and 72 organic layer samples from tussock grassland, and 244 mineral soil samples from pine plantation were collected and analysed for pH, total carbon and nitrogen concentration, dry bulk density (BD), and soil texture. The median soil pH values (0-10 cm depths) was 4.00 in tussock grassland and 3.91 in pine plantation, respectively. The pH values and bulk densities under both land use types increased with soil depth while carbon and nitrogen concentration decreased with depth. The texture of tussock grassland and pine plantation investigated in this study were dominated by sand (>50%). Carbon stocks in the organic layer were significantly different between land use types. 1.14 kg C/m2 in tussock grassland and 6.78 kg C/m2 in pine plantation. The median of soil organic carbon stock (SOC, 0-100 cm) in tussock and pine plantation was 21.36 kg C/m2 and 20.93 kg C/m2, respectively. The differences in SOC stock between these two land types were not significantly different. However, the SOC stock at 0-10 cm was significantly higher under tussock grassland (5.4 kg C/m2) than that under pine plantation (4.8 kg C/m2). Nitrogen stock was significantly higher in the pine plantation than that in tussock grassland. A significant negative correlation was found between SOC stock and soil pH in tussock grassland. This study suggests that pine plantation can store similar level of SOC as tussock grassland in mineral soils in the depth of 0-100 cm in Glendhu catchments, South Island, New Zealand.
