Phosphorus resources and fractions in peat-muck soils

sequential fractioning of phosphorus compounds was applied for the phosphorus speciation study – initially used in the research of bottom sediments and modified for the purpose of the research of organic sediments [ Jordan et al. 2007 ]. Sequential extraction made it possible to define the following operational fractions ( forms) of soil phosphorus: F1: (1 M NH 4 Cl), labile forms, loosely bound or absorbed, easily accessible; F2: (0.1 M Na 2 S 2 O 4 -NaHCO 3 ), forms bound on the surface of hydrated iron oxides (III) and hydrated manganese oxides (IV), released in
