Ammonia Emission Reducing and the Problem of the Nitrogen Management in Nowadays

Abstract

Ammonia (NH3) is derived from nitrogen-containing organic compounds, primarily from biological degradation of urea and proteins. Agricultural emissions can originate directly and indirectly from the animal's digestive tract, from the manure storage and from the soil. Emissions from livestock farms are affected by animal species, feed (N-effect), building characteristics (floor, ventilation, temperature) and manure storage (outside temperature, material used for coverage). The Directive on National Emission Ceilings, which is still in force today, sets the relevant limit values for emissions of certain air pollutants from 2010 onwards. This directive requires, among other things, Hungary (sulfur dioxide, nitrogen oxide) to reduce emissions of ammonia, which is the most significant for the agricultural sector. The required limits are 10% by 2020 and 32% by 2030 compared to 2005 values. In summary, reducing ammonia mitigation is a global problem. With my research, I intend to create a comprehensive picture of the current emission reduction regulations at national and international level. The publication is intended to provide an overview of international scientific discussions on ammonia emission reduction.
