Szukana fraza: [Abstract = "In presented paper the results of phosphorus content in the post\-mining grounds from the Łęknica locality, analyzed with the Egner\-Riehm method, in 0,1M HCl extract and subtotal form have been described. The content of appointed phosphorus forms, with except of top horizons, was very low. Phosphorus form content, appointed in the Egner\-Riehm extract has been especially low. Causes of this were exceptionally unfavourable proprieties of soils, in large measure caused by the pyrite presence in them, strongly acidifying dumped material."]
