Assessment of the relationship between atmospheric deposition of mineral nitrogen and vegetation in forest ecosystems

Resumo

This paper studies the composition and spatial distribution of the atmospheric deposition of mineral nitrogen (N_min) in forest ecosystems of Moscow, Vologda, and Kostroma regions. The composition of N_min depositions was shown to be affected by the nature of emissions and specialization of industrial enterprises, as well as the proximity of large highways. It was ascertained that forest stands significantly increased the concentration of N_min (ammonium and nitrate) in snowmelt. It was shown that the atmospheric depositions of N_min were not correlated with the distribution of nitrophilous species in the ground cover of the forests studied.
