Nitrogen deposition effects on soil organic matter chemistry are linked to variation in enzymes, ecosystems and size fractions Recent research has dramatically advanced our understanding of soil organic matter chemistry and the role of N in some organic matter transformations, but the effects of N deposition on soil C dynamics remain difficult to anticipate. We examined soil organic matter chemistry and enzyme kinetics in three size fractions (>250 Î&frac14;m, 63–250 Î&frac14;m, and <63 Î&frac14;m) following 6 years of simulated atmospheric N deposition in two ecosystems with contrasting litter biochemistry (sugar maple, Acer saccharum—basswood, Tilia americana and black oak, Quercus velutina—white oak, Q. alba). Ambient and simulated (80-kg NO3 −–N ha−1 year−1) atmospheric N deposition were studied in three replicate stands...
