Correction to: Biogeochemistry https://doi.org/10.1007/s10533-021-00855-y

The original version of this article unfortunately contained a typesetting mistake in Eq. (1).

The correct Equation is given below:

$$\updelta^{15}\text{N}({\permil }) =\frac{{^{15}\text{N}}_{sample}/{^{14}N}_{sample}-{^{15}\text{N}}_{reference}/{^{14}N}_{reference}}{{^{15}\text{N}}_{reference}/{^{14}N}_{reference}}\times 1000$$
(1)

The original article has been corrected.
