Descrição: The study aimed at the evaluation of the accumulation and vertical distribution of different forms of phosphorus (P) in reference to phosphorus sorption properties subject to mineral (NPK), mineral-organic (NPK + M), and organic (M) fertilisation. It was carried out in a long-term experimental field in Skierniewice (Central Poland) conducted since 1923 under rye monoculture. Total P content in the M and NPK soil profile was similar and lower than in the NPK + M soil. The content of organic P in Ap and Eet horizons of both manured soils was similar and higher than in the NPK soil. The Langmuir P sorption maximum (Smax) in the studied soils ranged from 39.7 to 90 mg P/kg, while the Freundlich P sorption coefficient aF ranged from 6.9 to 41.9 mg P/kg. Higher variability of parameters related to the binding energy from the Lanqmuir (k) and Freundlich (aF) equations was determined between soil horizons than between the fertilisation systems. Nonetheless, in M and NPK + M soils, sorption parameters aF and Smax and binding energy (k, bF) were considerably lower than in the NPK soil. The content of water extracted P in manured soils was higher than in the NPK soil.
