A dairy cattle farming is an important source of ammonia emissions, particularly in
Latvia. Models using a wide range in level of detail have been developed to represent or predict
these emissions. Besides, models are useful for improving the understanding of various farm
processes and their interacting effects on ammonia emissions. The model for ammonia emissions’
assessing or representing, predicting and comparing for manure management chain of dairy cattle
was created. The model provides a tool for evaluating mitigation and management strategies,
abatement measures and techniques to reduce of ammonia emissions and improve the
sustainability of dairy production systems both on the dairy farm and at the national level. It could
be used as a supplement tool for officials and experts. The model estimates those ammonia
abatement measures and techniques that have the highest emission reduction potential and
opportunities for implementation on Latvia’s dairy farms. The simulation model assesses the
ammonia emissions into each stage of the farming: animal housing, manure management -
manure handling and storage, and manure application. An important stage in reducing ammonia
emissions is manure storage. It should be noted that the main task of the model was to compare
the impact of the ammonia emission reduction options. When entering the number of animals,
the average nitrogen quantity per animal, the percentage distribution of manure quantities, the
first three levels of the program can be used to estimate the amount of nitrogen to be incorporated
into the soil and, as the difference; and the amount of ammonia emissions.
