Book Synopsis Evaluation of Soil Organic Matter Models by : David S. Powlson
Download or read book Evaluation of Soil Organic Matter Models written by David S. Powlson and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil organic matter (SOM) represents a major pool of carbon within the biosphere, roughly twice than in atmospheric CO2. SOM models embody our best understanding of soil carbon dynamics and are needed to predict how global environmental change will influence soil carbon stocks. These models are also required for evaluating the likely effectiveness of different mitigation options. The first important step towards systematically evaluating the suitability of SOM models for these purposes is to test their simulations against real data. Since changes in SOM occur slowly, long-term datasets are required. This volume brings together leading SOM model developers and experimentalists to test SOM models using long-term datasets from diverse ecosystems, land uses and climatic zones within the temperate region.

Book Synopsis Soil Processes and the Carbon Cycle by : Rattan Lal
Download or read book Soil Processes and the Carbon Cycle written by Rattan Lal and published by CRC Press. This book was released on 2018-02-06 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: World soils contain about 1500 gigatons of organic carbon. This large carbon reserve can increase atmospheric concentrations of CO2 by soil misuse or mismanagement, or it can reverse the 'greenhouse' effect by judicious land use and proper soil management. Soil Processes and the Carbon Cycle describes soil processes and their effects on the global carbon cycle while relating soil properties to soil quality and potential and actual carbon reserves in the soil. In addition, this book deals with modeling the carbon cycle in soil, and with methods of soil carbon determinations.

Book Synopsis Soil Carbon Storage by : Brajesh Singh
Download or read book Soil Carbon Storage written by Brajesh Singh and published by Academic Press. This book was released on 2018-04-12 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil Carbon Storage: Modulators, Mechanisms and Modeling takes a novel approach to the issue of soil carbon storage by considering soil C sequestration as a function of the interaction between biotic (e.g. microbes and plants) and abiotic (climate, soil types, management practices) modulators as a key driver of soil C. These modulators are central to C balance through their processing of C from both plant inputs and native soil organic matter. This book considers this concept in the light of state-of-the-art methodologies that elucidate these interactions and increase our understanding of a vitally important, but poorly characterized component of the global C cycle. The book provides soil scientists with a comprehensive, mechanistic, quantitative and predictive understanding of soil carbon storage. It presents a new framework that can be included in predictive models and management practices for better prediction and enhanced C storage in soils. - Identifies management practices to enhance storage of soil C under different agro-ecosystems, soil types and climatic conditions - Provides novel conceptual frameworks of biotic (especially microbial) and abiotic data to improve prediction of simulation model at plot to global scale - Advances the conceptual framework needed to support robust predictive models and sustainable land management practices

Book Synopsis Modeling Carbon and Nitrogen Dynamics for Soil Management by : M.J. Shaffer
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 2001-05-07 with total page 674 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.
