The oxygen isotopic composition of phosphate (δ18OP) has been increasingly used as an effective tracer for the biogeochemical cycling of phosphorus (P) in soils and other environments. However, diverse pretreatment methods (e.g. storage, preparation and extraction) are being used for soil samples. For the uniformity of methods as well as for the comparison of results, it is important to understand if specific treatment methods can compromise original δ18OPvalues. Here, Ag3PO4and KH2PO4were used to test whether a modified Hedley sequential extraction and purification procedure can a...
