Erratum: Ecologically implausible carbon response?

Strong gradients in nitrogen and carbon stocks at temperate forest edges

“…The potential C fixation response to N deposition is restricted by the C:N stoichiometry of the forest ecosystem pools . The results of Magnani et al (2007) imply that deposited N would solely lead to an increase in stem wood, which is the only C sink with a C:N ratio around 500 (de Vries et al, 2008). However, 15 N-labelled tracer experiments in temperate forests indicated that most N retention occurs in soil (Nadelhoffer et al, 1999).…”

“…According to Sleutel et al (2009) the leaching losses of dissolved organic N can be substantial (9-28% of the total amount of N leached). The C sequestration response to N deposition lay in the range reported by de Vries et al (2008), except for two low values in Qr2 and Pn1 (Table 4). The edge of Qr2 and interior plots of Pn2 were characterized by high N leaching values, which could be linked to the vicinity of a ditch, facilitating losses of dissolved N. Our soil C sequestration values were higher at the edge, explaining the higher C stocks.…”
