There’s a debate going on about the mandatory use of nitrogen inhibitors for urea fertilisers. Last year, AHDB reviewed the literature to reveal the science behind them and how they could be used to reduce emissions. CPM investigates. Nitrogen losses from solid urea application can range from 10-58%. By Lucy de la Pasture Many things in politics are uncertain, but it’s a sure thing that life will soon change as farming is shaped by the new Agriculture Bill. With clean air and clean water very much a focus of the government’s 25-year environment plan, ensuring efficient use of organic and inorganic fertilisers will likely be a key priority. The way change will be implemented is yet to be fully revealed, but there will be a focus on a greener environment, says AHDB resource management scientist, Dr Sajjad Awan. “Approximately 88% of ammonia (NH3) emissions in the UK are from agriculture, so farming practices that mitigate these losses will be necessary.” The arable sector loses nitrogen gases from its soils to the atmosphere – as NH3, nitrous oxide and other nitrogenous oxides (produced through nitrification/denitrification processes) – as well as losing nitrates into water through leaching. “Nitrogenous…
