Field study on the suitability of Fe-rich water treatment residuals for reducing internal P loading in peaty freshwater systems

The data of sequential phosphorus and iron extractions, solid phase and porewater analysis and sediment core incubation experiments performed on peaty freshwater sediments, and sequential iron extraction and solid phase analysis performed on iron-rich water treatment residuals used for Fe amendment, presented in Münch et al. (2025) submitted to Biogeochemistry. Details on the samples and methods can be found in the manuscript and the Electronic Supplementary Information.
