Nitrous oxide is greenhouse gas which causes the global warming.
Nitrous oxide can be produced microbiologically during nitrification as a by-product and during denitrification as an intermediate. Nitrous oxide production from unit process of denitrification and nitrification Nitrous oxide production in denitrification. Organic carbon to nitrate-n ratio is very important factor governing the production of nitrous oxide. NO3-N ratio can cause the nitrous oxide production. Nitrous oxide production in nitrification.
