In the original publication of the article, Table 4 and Fig. 4 were incorrectly published. The correct version is given in this correction.
The equations now given in Fig. 4 have implications for the text in Abstract. Hence, the following sentence “Soluble phosphorus (P) increased with sludge application rate, but represented only around 2% of the expected residual P according to P-balance calculations.” should be read as “Soluble phosphorus (P) increased with sludge application rate, but represented around 20% of the expected residual P according to P-balance calculations.”
In Results section under “Phosphorus” heading, the following sentence “This comparison showed that P recovered in the P-AL extract corresponded to 2.6 and 2.2% of net P deposits at Igelösa and Petersborg, respectively (Fig. 4).” should be read as “This comparison showed that P recovered in the P-AL extract corresponded to 26 and 22% of net P deposits at Igelösa and Petersborg, respectively (Fig. 4).”
In Discussion section under “Phosphorus” heading, the first sentence should have 20% instead of 2%. The second sentence “However, it is consistent with recent findings in Denmark, where the fertiliser value of SS treated with iron was found to be zero (Müller-Stöver et al. 2018).” should be removed.
