Potential measures for ammonia reduction in agriculture.

The Federal Environment Agency has examined the effects of measures to reduce ammonia in the agricultural sector. Potentials of individual measures as well as packages of measures for cattle and pig farming and fertilisation of agricultural soils were estimated. For cattle and pig farming, these packages include selected measures relating to feeding, slurry storage, slurry processing and manure application. Nitrogen fertilisation was analysed as part of a separate package of measures. In a Maximum Feasible scenario, selected measures were linked and modelled for the agricultural sector. In addition, the proposed measures were examined with regard to the calculation model of the Austrian Air Pollution Inventory.
