Abstract (in english)
   The effects of atmospheric deposition on N cycling in acidified soil were studied at three spruce and one beech forested sites in the Czech Rrepublic. Nitrogen content and 15 N were monitored in bulk and throughfall precipitation, needles, leaves, soils and soil solutions. Changes in soil NO3- production, effect of admixing of atmospheric N in spruce forest and N consumption in deciduous forest are described using changes in 15N fractionation of mineralized N in soil. Admixing of atmospheric NH4+ can be identified at low concentrations of exchangeable NH4+. The 15N ration of atmospheric NO3- input is on average by 2% less negative than the 15n ratio of atmospheric NO3- input is on average by 2% less negative than 5N ratio in soil water; admixing changes the 15N of soil NO3- detected in lysimeters
