NH3 Emissions Abatement Practices

Applies to: Silage Production


This indicator refers to the prevention of NH3 emissions from silage production. NH3 contributes to acid deposition and eutrophication, which in turn, can lead to potential changes occurring in soil and water quality. Common abatement measures include balanced fertilisation, efficient application method (e.g. incorporation of fertilisers, injection of fertilisers, band spreading of slurry), timing of application (avoiding winter application, synchronization with crops’ needs), dilution of slurry by at least 50%, application of fertilisers with irrigation water, use of urease inhibitors, application of slow release fertilisers, irrigation immediately following fertilizer application, substitution of urea with ammonium nitrate, use of nitrification inhibitors etc.
