Herbicide movement and persistence in Macquarie Island soils

This data set describes the persistence and movement of herbicides in 2 soil types from Macquarie Island. The soil characterization spreadsheet provides physical and chemical analyses of several Macquarie Island soils. A column leaching experiment was then used to assess the leaching and persistence in two Macquarie Island soils. Details of this experimental set up, and collection of leachate samples is provided in the Core leaching data spreadsheet. These samples were then analysed using LCMS to determine the concentration of glyphosate and AMPA in the leachate (Leachate samples_analysis)

本数据集记录了麦夸里岛（Macquarie Island）两种土壤类型中除草剂的持留与迁移特性。土壤特性表征电子表格提供了多份麦夸里岛土壤的理化分析数据。后续通过柱淋溶实验，对麦夸里岛两种土壤中的除草剂淋溶行为与持留特性进行了评估。本实验的装置细节及渗滤液样品的采集方案，详见核心淋溶数据电子表格。随后采用液相色谱-质谱联用（Liquid Chromatography-Mass Spectrometry, LCMS）对上述样品开展分析，以测定渗滤液中草甘膦（glyphosate）与氨基甲基膦酸（AMPA）的浓度，相关分析结果收录于《渗滤液样品分析》（Leachate samples_analysis）数据表中。
