标准范围

本文件规定了一种使用pH 7缓冲的摩尔乙酸铵溶液作为萃取剂测定土壤中潜在阳离子交换容量（CEC）和可交换阳离子（Ca、K、Mg、Na）含量的方法。本文件适用于根据ISO 11464制备的所有类型的风干土壤样品。

This document specifies a method for the determination of potential cation exchange capacity (CEC) and the content of exchangeable cations (Ca, K, Mg, Na) in soils using a molar ammonium acetate solution buffered at pH 7 as extractant.

This document is applicable to all types of air-dry soil samples which have been prepared, for example, according to ISO 11464.
