What percentage of Nitrous Oxide is emitted by using Nitrogen Fertilizers in Agriculture?
Has anyone quantified the amount of Nitrous Oxide emission by using fertilizers Like urea and if so in which location and on what crop has this research been carried Out?
The relevance of this question Under "Global Warming" is that Nitrous Oxide is indeed emitted due to fertilizers and it is 300 times More harmful than CO2 in adding to the Heat
Can't give you a figure specifically for the Use of fertilisers but as a whole argiculture is responsible for just under 15% of the Total greenhouse Gas emissions that contribute to global warming.
Nitrous oxide accounts for 46% of that 15% and can be divided into Two - 6% From Manure and 40% from soils and Soil additives.
40% of 15% is 6% so the total contribution to global warming from soils and additives is 6%.
The above figures are Carbon equivelances. Nitrous oxide is almost 300 times as potent as CO2 so the contribution by Volume is Very Small - about 0.02%.
