This book was released on 2015-03-16 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greenhouse gases (CO2 and N2O) play an important role in the atmospheric chemistry and in the global warming. According to the emissions inventories that governments submit to the UNFCCC, agriculture accounts for about 15 % of global GHGs. Agriculture contributes about half of the global emissions of two of the most potent non-carbon dioxide greenhouse gases nitrous oxide and methane. Nitrous oxide emissions from soils, fertilizers application and manures).Agricultural soils are considered sources of carbon dioxide emissions and nitrous oxide. The nitrogen fertilizer is the most important sources of nitrous oxide emissions.Clay soil fertilized with urea gave the largest amount of emissions of carbon dioxide and were15607 ppm, while in the control chambers were 9228 ppm (The proportion of clay soils contribute in the total emission amounted to 59.1% and was the carbon dioxide emitted by the urea ratio of 40.9%). Sandy soil fertilized with urea gave the highest emissions of nitrous oxide, where 6.07 ppm.In the first experiment we observe that the largest difference in temperature was 1.5 oC.In the second experiment also note that the largest difference in temperature was 1.73 oC .

This book was released on 2014-07-24 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present work evaluated the effect of mineral nitrogen (N) fertilizer application during crop production on the potential risk of gaseous N loss in the form of nitrous oxide (N2O). Nitrous oxide (N2O) is an environmentally important atmospheric trace gas and contributes to the anthropogenic greenhouse effect. In addition, it is a precursor to photochemical nitric oxide (NO) production in the stratosphere which leads to stratospheric ozone depletion. Agriculture is considered to be the main source of anthropogenic N2O, with agricultural soils representing the single largest source due to nitrogen fertilizer applications during crop production. The purpose of this study was to examine the effects of mineral N fertilizers (N form, amount, mode of application) on N2O emissions from fertilized croplands in north-west Germany. Therefore several field trials, one greenhouse pot experiment and two incubation experiments were conducted. Nitrous oxide fluxes were measured by means of the closed chamber method. The length of the experimental period varied between experiments from several weeks (42 days) up to one-year measurement campaigns. The amount of N2O emitted during the crop growth period depended on the N form applied as well as on the mode of application, and a linear relationship between cumulative N2O emissions and total N fertilizer amount applied was found.

Download or read book Agriculture and the Nitrogen Cycle written by Arvin Mosier and published by Island Press. This book was released on 2013-04-10 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is an essential element for plant growth and development and a key agricultural input-but in excess it can lead to a host of problems for human and ecological health. Across the globe, distribution of fertilizer nitrogen is very uneven, with some areas subject to nitrogen pollution and others suffering from reduced soil fertility, diminished crop production, and other consequences of inadequate supply. Agriculture and the Nitrogen Cycle provides a global assessment of the role of nitrogen fertilizer in the nitrogen cycle. The focus of the book is regional, emphasizing the need to maintain food and fiber production while minimizing environmental impacts where fertilizer is abundant, and the need to enhance fertilizer utilization in systems where nitrogen is limited. The book is derived from a workshop held by the Scientific Committee on Problems of the Environment (SCOPE) in Kampala, Uganda, that brought together the world's leading scientists to examine and discuss the nitrogen cycle and related problems. It contains an overview chapter that summarizes the group's findings, four chapters on cross-cutting issues, and thirteen background chapters. The book offers a unique synthesis and provides an up-to-date, broad perspective on the issues of nitrogen fertilizer in food production and the interaction of nitrogen and the environment.
