What accounts for the global warming emissions associated with synthetic fertilizers?

All of the above-synthetic fertilizers require a lot of energy to manufacture, package, and transportwhich generates a significant amount of global warming pollution. in addition, the overuse of fertilizerseven organic ones like compost or animal manurecan create additional global warming pollution in the form of nitrous oxide. nitrous oxide, while far less prevalent in the atmosphere than carbon dioxide, is 320 times more potent as a heat-trapping gas. on average, crops in the united states absorb less than half of the nitrogen fertilizer applied to them. some of the excess runs off into rivers and other bodies of surface water, some seeps into groundwater, and some is converted into nitrous oxide. according to the environmental protection agency, agricultural soil management accounts for two-thirds of the nations human-induced nitrous oxide emissions.
