DESCRIPTION
ISO/TS 22171:2023
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.
