ABSTRACT
The investigations were carried out in 2001. The direction of the transformation of nitrogen compounds in soils under a forest island as a biogeochemical barrier located on muckous soils was presented. It was confirmed that increase of yearly mean concentrations of nitrates, ammonium, total nitrogen, total amount of bound amino acids in humic acids (HA), urease activity, dissolved organic carbon were similar to the flow of ground water under the forest island. Increase in urease activity is connected with the changes of mineral and organic forms of nitrogen.

W pracy przedstawiono kierunek przemian związków azotu w glebach murszastych na przykładzie wyspy leśnej pełniącej funkcję bariery biogeochemicznej. Wykazano w badanych glebach zwiększenie średnich sezonowych zawartości jonów amonowych i azotanowych oraz azotu ogólnego i sumarycznej zawartości aminokwasów związanych w kwasach huminowych (HA) w kierunku zgodnym z przepływem wody gruntowej. To samo zjawisko zaobserwowano dla zmian aktywności ureazy i rozpuszczonego węgla organicznego.
