This study is focused on a comparative analysis of atmospheric N-NO3- and N-NH4+ deposition in the open field and under the forest canopy of the Republic of Moldova, which are included in a systematic transnational grid (16x16 km) of forest monitoring throughout Europe. Also, it was appreciated the role of the canopy to reduce the variability of the pH of the precipitation. Monitoring the flux of pollutant ions was performed according to the methodology recommended by International Co-operative Programme on Assessment and Monitoring of Air Pollution Effects on Forests (ICP Forests) (ICP Forests, 2010). The N-NO3- and N-NH4+ deposition under forest canopy have tended lower in vegetative rest period. The N-NH4+ flux is 1.7-3.8 times more than the N-NO3- flux, which clearly demonstrates the dominance of ammonium ion to nitrate ion in atmospheric deposition of Republic of Moldova. |
