Flows of nitrate ions NO3- and amonnium ions NH4+ in biologically active layers of soil were measured, using ionexes, at forest stands in northern -- eastern regions of Czech republic, between May and September, 2010. Seasonal amounts, expressed in mg.(m2)-1, were analysed, focused on its relations with tree species compositon, impact of tree rhisosphere (location of ionexes close to the tree stems, or in a few meters distance), and forest altitudinal vegetation zones. NO3- showed significantly higher values, as compared to NH4+, and its values were more influenced by tree species composition. Norway spruce (Picea Abies [L.] Karst.), European birch (Betula pendula Roth.) and European beech (Fagus sylvatica L.) were recognised as a tree species with significantly low seasonal amounts of nitrogen ions NO3-. Sycamore maple (Acer pseudoplatanus L.) was recognised as a tree species with the significantly wide range of NH4+seasonal amounts values. Impacts of forest altitudinal vegetation zones, and tree rhisosphere, were recognised as insignificant, respectively inconclusive
