标准摘要
[中文适用范围]： 本文件规定了测定土壤氧化还原电位（Eh）的现场方法。 注：只有当相关土壤层具有根据附录 D 中的类别定义为新鲜或湿润的湿度状态时，才可以进行本文件中描述的氧化还原电位的电化学测量。 [外文原描述]： This document specifies a field method for the determination of soil redox potential ( E h). NOTE The electrochemical measurement of redox potential described in this document is possible only if the relevant soil horizon has a moisture status defined as fresh or wetter according to the classes presented in Annex D.
