o:4634 Phosphorus retention in peat amended with iron-containing clinoptilolite en Abstract: Although phosphorus (P) is a crucial plant nutrient, it is associated with environmental problems such as eutrophication. The effect of Fe(III)-containing natural clinoptilolite (FeCLI) on P retention in peat soil, an acidic soil typically high in organic matter, was studied by a batch method. The effect was investigated both in pure peat and lime-amended peat. The peat amount and the rate of lime influenced the retention efficiency of FeCLI. The acidity of both pure peat and peat that have been amended with lime was decreased in the presence of FeCLI. All obtained results suggested that FeCLI can be considered as a beneficial soil supplement to support both soil fertility and water preservation. natural zeolite, iron–clinoptilolite, peat, organic soil, phosphorus 1552100 978-961-96672-0-0 2024-05-27T11:46:21.750Z 44 no 46 Jelena Pavlović Institute of Soil Science 0000-0001-9424-1080 46 Tore Krogstad Faculty of Environmental Science and Natural Resource Management, Norwegian University of Life Sciences, N-1432 Aas, Norway 46 Nevenka Rajić The University “UNION – Nikola Tesla”, Cara Dušana 62–64, 11158 Belgrade, Serbia application/pdf 1388924 https://unilib.phaidrabg.rs/o:4634 no yes 1 70 92000004 71A05 10 Slovenian-Serbian-Croatian Symposium on Zeolites 2024
