ABSTRACT
The function of a shelterbelt as a biogeochemical barrier located on two different kinds of soil: mineral and mineral-organic, was investigated on the background of changes in the total nitrogen content, average yearly concentration of ammonia, nitrate ions, activity or urease, and structure of humic acids. Transformation of different nitrogen forms in the soil under the shelterbelt was strongly connected with the humification processes and molecular structure of humic acids.

Przedstawiono funkcjonowanie pasa zadrzewień jako bariery biogeochemicznej zlokalizowanej na dwóch typach gleb: mineralnej i mineralno-organicznej na podstawie zmian azotu ogólnego, średniego rocznego stężenia jonów amonowych, jonów azotanowych, aktywności ureazy, pH oraz badań struktury kwasów huminowych (HA). Stwierdzono zależność transformacji różnych form azotu w glebie pod pasem zadrzewień od procesu humifikacji oraz molekularnej struktury HA.
