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