Carbon and Nitrogen Pools in Terrestrial Ecosystems -- Carbon and Nitrogen Cycles in Terrestrial Ecosystems -- Soil Organic Matter Characterization -- Organic Matter and Soil Quality -- Carbon and Nitrogen Transformations in Soils -- Anthropogenic Activities and Soil Carbon and Nitrogen -- Leaching Losses and Groundwater Pollution -- Bidirectional Biosphere-Atmosphere Interactions -- Modeling Carbon and Nitrogen Dynamics in the Soil-Plant-Atmosphere System. Carbon and Nitrogen in the Terrestrial Environment is a comprehensive, interdisciplinary description of C and N fluxes between the atmosphere and the terrestrial biosphere; issues related to C and N management in different ecosystems and their implications for the environment and global climate change; and the approaches to mitigate emission of greenhouse gases. Drawing upon the most up-to-date books, journals, bulletins, reports, symposia proceedings and internet sources documenting interrelationships between different aspects of C and N cycling in the terrestrial environment, Carbon and Nitrogen in the Terrestrial Environment fills the gap left by most of the currently available books on C and N cycling. They either deal with a single element of an ecosystem, or are related to one or a few selected aspects like soil organic matter (SOM) and agricultural or forest management, emission of greenhouse gases, global climate change or modeling of SOM dynamics.
