What’s the link between fertiliser use and climate change?
Fertiliser is a small contributor to climate change through the creation of greenhouse gases. These come mainly from nitrogen. Fertiliser nitrogen produces nitrous oxide emissions as a result of the natural biological soil processes of nitrification and denitrification.
Only about 10% of all agricultural nitrous oxide emissions are generated directly from fertiliser. In fact, the majority of nitrous oxide emissions from agriculture come from livestock dung and urine patches. This source of greenhouse gas is being addressed by The Fertiliser Associations' member companies developing nitrification inhibitor products which reduce nitrous oxide emissions.
