Crops are a significant source of GHG emissions and arable systems offer many opportunities to use new techniques to help reduce carbon footprints and benefit the bottom line. The most significant GHG emission from arable cropping in the UK is associated with the use of artificial nitrogen fertilisers. The other significant operation is cultivations (frequency, intensity and depth) and the effect that has on Soil Organic Matter and consequent GHG emissions.

Focussing on where emissions are found in arable production systems and what we can do about them.
A significant (50%) proportion of the GHG emissions associated with Nitrogen fertilisers come from production.
How the other 50% of GHG emissions associated with fertilisers occur are more under direct farm management control.
