现场lysimetry和孔隙水采样允许研究人员评估施用到土壤和植被建立化学品的命运。本协议的目的是演示如何安装所需的仪表和过程集成领域lysimetry和孔隙水采样实验收集样本，进行化学分析。

该程序的总体目标是展示田间对称性和土壤倒注水采样技术，用于分析应用于土壤和已建立植被的化学品的命运。这是通过首先将溶度计安装到坡度很小或没有坡度的区域的土壤中来实现的。第二步是将倒入水采样器安装到溶度计内的所需深度。

接下来，在两周的适应期后进行化学应用。最后一步是对贫水、土壤和树叶进行采样，以确定处理后特定评估日期的化学分布。最终，田间百合的综合对称性和不良的水采样为确定环境中化学物质的分布和潜在风险提供了有价值的工具。
