Which green house gas other than methane is produced by agricultural fields?
Nitrous oxide
Sulphur Dioxide
Ammonia
Arsenic
Nitrous oxide
Nitrous oxide is a powerful greenhouse gas produced by soil cultivation practices, especially the use of commercial organic fertilizers (including manure), biomass burning etc, This is done by a process of nitrification which converts the nitrogen in fertilizer to the production of nitrous oxide. The excessive use of the fertilizers thereby results in an increase in the nitrous oxide production.
