Nitrogen enrichments not only influence microbial
community composition but also can strongly impact
microbial C dynamics – though not in ways that would
be predicted from traditional limitation theory
(Vitousek & Howarth, 1991) as N enrichments typically
decrease microbial activity. Strong reductions in soil
microbial activities have been documented in both field
and lab-based studies with the magnitude of the reduction
in soil respiration and microbial biomass strongl
