Abstract. This study compared the soil air composition in structural and conventional tree soils used for roadside plantings in the City of
Helsinki, Finland. Soil air samples, collected from three depths during the growing seasons of 2012 and 2013, were analyzed for oxygen
concentrations. The effect of soil cover on the soil–atmosphere gas flux was evaluated using relative gas diffusion coefficients as estimated
from in situ measurements of CO2 fluxes and CO2 concentrations in soil air. The average O2 concentrations were higher in structural than
in conventional soil air in both years. No obvious depth profile for the O2 concentration was detected. Structural soil aeration appears
more favorable for root growth than aeration in conventional tree soil. However, soil aeration was also sufficient for healthy tree growth in
the conventional soil. Cobblestone paving did not severely impair ground ventilation as compared with a cast-iron grate.
