4.1 Source reduction

• The most elegant approach to minimizing nitrous oxide emissions is to drastically reduce their production at source.

  In the case of diffuse emissions generated by agricultural soils, N ₂ O production is the direct consequence of nitrogen transformations by soil bacteria (ie, nitrification and denitrification). To produce less N ₂ O, soils should be treated less with nitrogen fertilizers. This solution is only conceivable if nitrogen fertilization of...
