Atmosphere Fertilizer

global methane concentrations (surface , atmospheric) 2005; note distinct plumes

through increasing use of nitrogen fertilizer, used @ rate of 110 million tons (of n) per year in 2012, adding existing amount of reactive nitrogen, nitrous oxide (n2o) has become third important greenhouse gas after carbon dioxide , methane. has global warming potential 296 times larger equal mass of carbon dioxide , contributes stratospheric ozone depletion. changing processes , procedures, possible mitigate some, not all, of these effects on anthropogenic climate change.

methane emissions crop fields (notably rice paddy fields) increased application of ammonium-based fertilizers. these emissions contribute global climate change methane potent greenhouse gas.
