Book Description
Plants take up only 50 percent of the nitrogen fertilizer applied to agricultural land. Part of this inefficiency is a result of emissions of ammonia (NH3 ), nitrous oxide (N2O) and nitric oxide (NO). Quantifying these emisions is important, both as part of an attempt to improve fertilizer use efficiency and because of their influence on ecosystems, atmospheric pollution and the so-called greenhouse effect. This report provides a comprehensive review of the literature about emissions of NH3, N2O and NO, and examines the regulating factors, measurement techniques and models. It draws these data together and generates global emission estimates that can serve as a basis for further addressing the issues of efficiency and environmental impact.

Book Description
The National Emission Model for Agriculture (NEMA) is used to calculate emissions to air from agricultural activities in the Netherlands on a national scale. Emissions of ammonia (NH3) and other N compounds (NOx and N2O) are calculated for animal housing, manure storage, manure application and grazing using a flow model for total ammoniacal nitrogen (TAN). Emissions from the application of inorganic N fertilizer, compost and sewage sludge, cultivation of organic soils, crop residues, and ripening of crops are calculated as well. The NEMA is also used to estimate emissions of methane (CH4) from enteric fermentation and manure management, nonmethane volatile organic compounds (NMVOC) and particulate matter (PM) from manure management and agricultural soils, as well as for carbon dioxide (CO2) from liming. Emissions are calculated in accordance with the criteria of international guidelines and reported in an annual Informative Inventory Report (IIR; for air pollutants) and National Inventory Report (NIR; for greenhouse gases). This methodology report provides an outline of and describes the background to the calculation of emissions according to the NEMA.

Book Description
Synthesizing 40 years of ongoing ecological research, this book examines the structure, function, and dynamics of the Lamto humid savanna. From the history of the Lamto ecology station, to an overview of enivronmental conditions of the site, and examining the integrative view of energy and nutrient fluxes relative to the dynamics of the region's vegetation, this exacting work is as unique and treasured as Lamto itself.
