Erratum to: Biogeochemistry (2017) 132:213–231 DOI 10.1007/s10533-017-0299-8

In the PDF and printed version of this article Eq. (1) on p. 219 contains an error: the terms of the denominator appear twice. Eq. (1) should read as follows:

$$ ^{15} {\text{N}}_{\text{rec}} = {{\left[ {m_{\text{pool}} \left( {{\text{at}}.\,\%^{15} {\text{N}}_{\text{pool}} -{\text{at}}.\,\% \,^{15} {\text{N}}_{\text{ref}} } \right)} \right]} \mathord{\left/ {\vphantom {{\left[ {m_{\text{pool}} \left( {{\text{at}}.\,\%^{15} {\text{N}}_{\text{pool}} {-}{\text{at}}.\,\% \,^{15} {\text{N}}_{\text{ref}} } \right)} \right]} {\left( {{\text{at}}.\,\%^{15} {\text{N}}_{\text{tracer}} {-}{\text{at}}.\,\% \,^{15} {\text{N}}_{\text{ref}} } \right)}}} \right. \kern-0pt} {\left( {{\text{at}}.\,\%^{15} {\text{N}}_{\text{tracer}} -{\text{at}}.\,\% \,^{15} {\text{N}}_{\text{ref}} } \right)}} $$

The online version of the article is correct.

The publishers apologize for the inconvenience caused.
