   Stable isotope systematics of C, N and S were studied in soils of 5 European forest ecosystems. In Picea stands, the behavior of C, N and S isotopes was similar in 3 aspects: (1) assimilation favored the lighter isotopes C-12, N-14 and S-32; (2) mineralization in the soil profile left in situ residues enriched in the heavier isotopes C-13, N-15 and S-34; and (3) NO3-N as well as SO4-S in soil solution was isotopically lighter compared to the same species in the atmospheric input. Stable isotope systematics of Jezeri soil S (mean of 2.5parts per thousand in the O + A horizon, 4.8parts per thousand in the B horizon, and 5.8parts per thousand in the bedrock) suggests that most of the soil-derived S in discharge must come from the isotopically light organic S present in the upper soil horizon, and that mineralized organically-cycled S is mainly flushed out during the spring snowmelt.
