Communications in Soil Science and Plant Analysis, 41(3), 290-300.0010-3624https://doi.org/10.1080/00103620903460807https://www.tandfonline.com/doi/full/10.1080/00103620903460807http://hdl.handle.net/11452/27736This study was conducted to compare the most appropriate method for the evaluation of available iron (Fe) status of calcareous soils by using nine different chemical extraction methods. Leaf and soil samples were collected from nine peach (Prunus persica L.) orchards, each of which included green, slightly chlorotic, and severely chlorotic peach trees. According to the chlorosis degrees of the leaves, total and active Fe contents and some soil properties were determined. Relationships between these parameters and Fe amounts obtained from the methods were correlated. Among the methods tested, method 3 (M3) [0.05 N hydrochloric acid (HCl) + 0.025 N sulfuric acid (H(2)SO(4))] and method 8 (M8) 0.05 M ethylenediaminetetraacetic acid (EDTA) (pH 7.0) were the most suitable methods to indicate the available Fe status of the soils.eninfo:eu-repo/semantics/closedAccessAvailable ironExtraction methodsPeachSoilMicro-nutrientsPeach-treesChlorosisLeavesMacroDeficiencyCopperCitrusZincAgriculturePlant sciencesChemistryPrunusPrunus persicaAcetic acidCalcareous soilComparative studyDicotyledonExtraction methodHydrochloric acidIronSoil testSulfuric acidArticle0002742866000062-s2.0-77949336270290300413AgronomyPlant sciencesChemistry, analyticalSoil sciencePhytosiderophores; Chlorosis; Graminaceous Plant
