Nitrogen Deposition

Effects and implications

Sphagnum species will be vulnerable to N both through direct N induced toxicity and indirectly from shading by increased vascular plants growth. The extent to which shading occurs will reflect the capacity of the vascular plants to use the addition N to increase C assimilation. Molinia caerulea , despite having a relatively low Ellenberg N score appears to be a nitrophile in the presence of high NH₄⁺ concentrations (van den Berg pers comm.).
