Abstract

The reactive compounds of nitrogen adversely affect different forms of life on Earth. Around 86% of NH3 and 70% of N2O emissions in the Netherlands come from agricultural activities. Thus, new strategies need to be applied in order to overcome the problem of nitrogen. Therefore, the main goal of this research was to find methods that can be effective in reducing the nitrogen emissions from dairy farms; for this purpose, a number of scenarios have been researched that could potentially emit less reactive nitrogen compounds. Two scenarios with lowest amount of emissions have been introduced in the report. The method that can reduce the emissions of NH3 and N2O with minimal controversy among different sources is artificial covering of the manure storage which should be applied in all facilities of dairy farms. However, it should also be noted that anaerobic digestion will increase the emissions of both nitrogen compounds and should not be used individually without a subsequent mitigating strategy. Furthermore, the amount of reduction achieved by some of these methods vary very greatly. The characteristics of soil, i.e. pH and moisture and the surrounding environment conditions such as wind speed, temperature, precipitation and humidity are some of the parameters that affect the amount of emissions and the effectiveness of mitigating strategies. Therefore, more research in this field is required to definitively indicate correct measures fitting different cases.
