The paper presents the results of long-term research to determine the content of phosphorus in drained peat soils and the influence of agro-meliorative techniques on its dynamics. The objects of research were medium-power peat soils on the typical genesis for subtaiga (Yernyakul bog located on the watershed of Tobol and Vagai rivers; Usalskoe bog – on the second floodplain terrace of Tobol river) and forest steppe (Tarmanskoe bog, Reshetnikovo object located on the second floodplain terrace of Tura river) of Northern Trans-Ural region. It has been revealed that the gross phosphorus content in drained peat soils is 0.1–0.3 %. The main part (83.8–95.2 %) of phosphorus in peat soil is in the form of organic compounds. The ratio of mobile phosphorus to its gross content corresponds to 4.8–16.2 %. The mobility of phosphorus during the 40-summer period increases insignificantly and only in the arable layer. The increase in the content of phosphorus is achieved by the use of phosphorus fertilizers and, to a lesser extent, the strengthening of the processes of mineralization of peat. Poor mobility and good availability of phosphorus plants on peat soils allows to put it in stock for 5 years.
