Nitrogen Oxide Soil Emission Measurements Using Passive Samplers and Static Chamber Method

Abstract

Nitrogen oxides play a major role in atmospheric chemistry, like primary pollutants, in the formation of secondary air pollutants or greenhouse gases (GHGs). This research study was conducted in the Western Pannonian sub-region of Croatia with the aim to determine the suitability of our internally developed passive sampler and static chamber method for N-NO₂ concentration measurement. The aim was also to determine the impact of mineral soil fertilization on the N-NO₂ flux during triticale vegetation. The research showed that the method used was suitable. Average daily N-NO₂ flux ranged from 2.78 to 5.09 mg ha^–1 day^–1 depending on phenophase and treatment. Statistically significant differences in N-NO₂ flux between two monitored treatments (300 kg N ha^–1 and 0 kg N ha^–1) were not observed, nor between two investigated phenophases.
