The paper contains the results of the research on the content of phosphorus and its speciation in the soils formed from postmining lands after over thirty years of their reclamation. Experimental factors included two crop rotations: frumentaceousrapeseed and fodder-frumentaceous, and three fertilization levels: 0NPK, 1NPK and 2NPK. Fractioning was conducted with Hedley’s method. Total content of phosphorus oscillated between 397,2 and 935,8 mg P · kg-1of soil. The content of all the analysed forms of phosphorus increased along with the growth of fertilization level and was between 6,27 and 24,6 mg P · kg-1 of soil - for water-soluble phosphorus, 5,5 and 50,8 mg P · kg-1 of soil for 0,5 mole · dm-3 NaHCO3 extracted phosphorus, 5,2 and 44,4 mg P · kg-1of soil for 0,1 mole · dm-3 NaOH extracted phosphorus, 227,0 and 649,2 mg P · kg-1of soil for 1 mole · dm-3 HCl phosphorus and 60,9 and113,5 mg P · kg-1of soil for residual phosphorus. Statistically important differences have arisen between the same combinations of mineral fertilization implemented in the analysed crop rotations. Higher content of phosphorus both in total and the majority of analysed fractions, was found in the samples collected from the fields with fodder-frumentaceous crop rotation.
