N2O, N2 and NH3 emissions following different slurry and digestate application techniques

  • In Germany, about 95% of ammonia (NH3) emissions originate from agriculture 40% from the application of slurry and digestate.


  •  In Germany, agriculture accounts for about 7% of total greenhouse gas (GHG) emissions 50% are
    produced in agricultural soils in the form of nitrous oxide (N2O).


  • With the amendment of the Fertilizer Ordinance 2017,
    the application of slurry and digestate in autumn on
    arable land is strongly restricted.


  • The application of slurry and digestate will therefore increasingly take place in the spring into growing crops with near-ground application techniques and without
    the possibility of direct incorporation into the soil, which may enhance emissions.
