%X Nitrous oxide(N 2O) is one of the important greenhouse gases. Althoug h it contributes only 5% global warming potential, great attention has been give n to it due to its depletion of ozone layer of stratosphere. It is estimated tha t soil contributes to 70% of anthropogenic N 2O sources. Nitrification and deni trifcation dominated by soil microorganisms are two main sources for emission of soil N 2O. Therefore, all soil physical, chemical and biological properties af fecting microbial activities will i...
