Ammonia and nitrous oxide emissions from agriculture due to the fertilizer applications

The forming and releasing procedures for both gases, NH_3 and N_2O, from agriculture due to fertilizer application are discussed in this paper. N_2O is one of the important greenhouse gases, while volatilization of NH_3 from agriculture shows not only loss of fertilizers(including manure), known as a waste of resources, but also environmental issues.Control of above-mentioned gas emmission will be responsibility for fertilizer industry in future.
