Zróżnicowanie zawartości różnych frakcji fosforu w glebach łąk porolnych w sąsiedztwie składowiska nawozów mineralnych w Tarnawie Wyżnej (Bieszczady)
Diversity of different fractions of phosphorus in grassland soils of agricultural lands in the vicinity of a fertilizer stockpile in Tarnawa Wyżna (We

Summary/Abstract: The paper presents a study on the diversity of different fractions of phosphorus in former agricultural (grassland) soils around a stockpile of mineral fertilizers in Tarnawa Wyżna (Bieszczady National Park). The main properties taken into consideration include basic soil analyses and extractions of phosphorus forms (Porg, Plab, P-Al, P-Fe, P-Ca). The total phosphorus content is calculated as the sum of organic and mineral phosphorus. The main aim of the study is to present the content of different forms of phosphorus in the profiles of typical grassland soils in Tarnawa Wyżna as well as to the spatial diversity of these forms in the uppermost soil horizons in relation to the basic properties of the soil. The results indicate that the analyzed soils are characterized by a distribution of phosphorus and its various fractions typical of slightly acidic Cambisols and grassland soils used for agricultural purposes.
